This replaces simple boolean \"approximate: true/false\" with richer modeling.\n**UNCERTAINTY LEVELS**:\n| Level | Label | Description | Example | |-------|-------|-------------|---------| | EXACT | Exact | Known with certainty | \"1880-03-15\" | | APPROXIMATE | Approximate | Close but not exact | \"circa 1880\" | | ESTIMATED | Estimated | Calculated/inferred | \"estimated 1875-1885\" | | UNCERTAIN | Uncertain | Significant doubt | \"possibly 19th century\" | | UNKNOWN | Unknown | Cannot be determined | \"date unknown\" |\n**CIDOC-CRM ALIGNMENT**:\nCIDOC-CRM models time-span precision through E52_Time-Span with fuzzy boundaries. ApproximationStatus provides a complementary vocabulary for expressing certainty levels.\n**USE CASES**:\n1. **Date Uncertainty**:\

     description: "Archive preserving materials for future use but with NO CURRENT ACCESS.\n\n**Wikidata**: Q112796578 (Dark Archive)\n\n**DEFINITION**:\n\nDark Archive is a preservation repository where materials are stored with \nNO ACCESS provided to users. The primary purpose is long-term preservation\nrather than current use. Access may be triggered by specific future events.\n\n**ACCESS SPECTRUM** (Light/Dim/Dark classification):\n\n| Type | Access Level | Purpose |\n|------|--------------|---------|\n| Light Archive (Q112815447) | Broadly accessible | Discovery & use |\n| Dim Archive (Q112796779) | Limited access | Selective access |\n| **Dark Archive** | No current access | Preservation only |\n\n**COMMON USE CASES**:\n\n1. **Digital Preservation**\n   - Trusted Digital Repositories (TDR)\n   - Backup/disaster recovery copies\n   - Integrity verification archives\n\n2. **Rights-Restricted Content**\n   - Orphan works awaiting rights clearance\n   - Embargoed materials\n   - Donor\
       \ restrictions (sealed for X years)\n\n3. **Sensitive Materials**\n   - Security-classified records\n   - Privacy-protected personal data\n   - Legally sealed court records\n\n4. **Format Migration**\n   - Source materials preserved after migration\n   - Original files kept for verification\n\n**TRIGGER EVENTS** (when dark becomes accessible):\n- Expiration of embargo period\n- Rights clearance obtained\n- Donor permission granted\n- Declassification decision\n- Original system failure (disaster recovery)\n\n**MULTILINGUAL LABELS**:\n- Dark Archive (de) [uses English term]\n\n**RELATED TYPES**:\n- LightArchive (Q112815447) - broadly accessible\n- DimArchive (Q112796779) - limited access\n- ClosedSpace - physical restricted access areas\n\n**ONTOLOGICAL ALIGNMENT**:\n- **SKOS**: skos:Concept (type classification)\n- **PREMIS**: premis:RightsStatus for access restrictions\n- **RiC-O**: rico:RecordSet with access restrictions\n- **Wikidata**: Q112796578\n\n**PREMIS INTEGRATION**:\n\n\
       Dark archives typically use PREMIS for preservation metadata:\n- `premis:RightsStatus` to document access restrictions\n- `premis:endDate` for embargo expiration dates\n- `premis:Agent` to identify the responsible custodian\n"

       \ delimited and coherent processes and states, \neither deliberately or spontaneously caused by E39 Actors, that result in \nchanges in E18 Physical Things.\"\n\nKey relationships:\n- crm:P4_has_time-span \u2192 TimeSpan (when)\n- crm:P7_took_place_at \u2192 Place (where)\n- crm:P11_had_participant \u2192 Actor (who)\n- crm:P2_has_type \u2192 EventTypeEnum (what kind)\n\n**RELATIONSHIP TO EXISTING OrganizationalChangeEvent**:\n\nOrganizationalChangeEvent already exists and maps to crm:E5_Event.\nThis Event class provides:\n1.

     description: "An observation of a person serving in a staff role at a heritage custodian institution,\nas documented in a specific source at a specific point in time.\n\n**PiCo Pattern Adaptation**:\nThe PiCo (Persons in Context) ontology distinguishes between:\n- **PersonObservation**: Data about a person as found in a source (evidence-based)\n- **PersonReconstruction**: Aggregated identity from multiple observations (inferred)\n\nFor heritage custodian staff tracking, we adapt this pattern:\n- **PersonObservation**: Staff role as documented in institutional sources\n  (annual reports, org charts, staff directories, archival records)\n- Focus on ROLES and AFFILIATIONS rather than biographical details\n- Temporal validity tracks employment period in specific position\n\n**Key Distinction from General Person Data**:\nThis class models INSTITUTIONAL ROLES, not complete biographical data:\n- Emphasis: Role, title, unit affiliation, employment dates\n- NOT: Full biographical reconstruction\
-      \ (birth, death, family, etc.)\n- Sources: Institutional records (not vital records, census, etc.)\n- PiCo: `pico:PersonObservation` (primary - person data from sources)\n- Schema.org: `schema:Person` (for person identity)\n- Schema.org: `schema:Role` (for organizational role)\n- CIDOC-CRM: `crm:E21_Person` (person as cultural heritage actor)\n- PROV-O: `prov:Agent` (person as responsible agent)\n- FOAF: `foaf:Person` (person in social network)\n\n**Hub Architecture Integration**:\n- PersonObservation refers to Person hub via `refers_to_person` (PICO pattern)\n- PersonObservation refers to OrganizationUnit via `is_or_was_affiliated_with`\n- OrganizationalStructure refers back via `staff_members` (bidirectional)\n- PersonObservation affected by OrganizationalChangeEvent via `affected_by_event`\n- Person hub links to Event via `participated_in_events`\n- Temporal alignment: employment dates vs. organizational unit validity\n\n**Use Cases**:\n1. **Staff directories**: Document current\

This includes:\n- Staff names, titles, and roles\n- Contact information (if publicly available)\n- Professional history and education\n- Affiliations and expertise areas\n\n**VERIFIABILITY PRINCIPLE**\n\nLike the base WebClaim class, PersonWebClaim follows the \"XPath or Remove\" principle:\n- Claims from web pages MUST have has_or_had_provenance_path with XPath expression\n- Claims from APIs (LinkedIn via Exa) may omit has_or_had_provenance_path but MUST have source_url\n- Claims without any verifiable source are FABRICATED and must be removed\n\n**SOURCE HIERARCHY**\n\nWhen multiple sources provide the same information:\n1. Official institutional website (highest reliability)\n2. LinkedIn profile (high reliability)\n3. News articles/press releases (medium-high)\n\

Third-party databases (lower)\n\nDocument all sources when available; note conflicts.\n\n**CLAIM TYPES**\n\nCommon claim types for heritage institution staff:\n- **full_name**: Complete name as displayed\n- **role_title**: Job title (e.g., \"Senior Curator\")\n- **department**: Organizational unit\n- **email**: Professional contact (only if public)\n- **biography**: Professional bio text\n- **specialization**: Expertise areas\n- **education**: Degrees and institutions\n\n**EXTRACTION WORKFLOW**\n\n1. SCRAPE institutional staff/team pages with FireCrawl\n2. EXTRACT names and roles with XPath locations stored in has_or_had_provenance_path\n3. SEARCH LinkedIn for additional profile data\n4.

+    description: "A verifiable claim about a person extracted from a web page with provenance.\n\n**RULE 26 COMPLIANCE: Person Data Provenance**\n\nAll person/staff data associated with heritage custodians MUST have\nweb claim provenance. This includes:\n- Staff names, titles, and roles\n- Contact information (if publicly available)\n- Professional history and education\n- Affiliations and expertise areas\n\n**VERIFIABILITY PRINCIPLE**\n\nLike the base WebClaim class, PersonWebClaim follows the \"XPath or Remove\" principle:\n- Claims from web pages MUST have has_provenance_path with XPath expression\n- Claims from APIs (LinkedIn via Exa) may omit has_provenance_path but MUST have source_url\n- Claims without any verifiable source are FABRICATED and must be removed\n\n**SOURCE HIERARCHY**\n\nWhen multiple sources provide the same information:\n1. Official institutional website (highest reliability)\n2. LinkedIn profile (high reliability)\n3. News articles/press releases (medium-high)\n\
+      4. Conference programs (medium)\n5. Academic publications (medium)\n6. Third-party databases (lower)\n\nDocument all sources when available; note conflicts.\n\n**CLAIM TYPES**\n\nCommon claim types for heritage institution staff:\n- **full_name**: Complete name as displayed\n- **role_title**: Job title (e.g., \"Senior Curator\")\n- **department**: Organizational unit\n- **email**: Professional contact (only if public)\n- **biography**: Professional bio text\n- **specialization**: Expertise areas\n- **education**: Degrees and institutions\n\n**EXTRACTION WORKFLOW**\n\n1. SCRAPE institutional staff/team pages with FireCrawl\n2. EXTRACT names and roles with XPath locations stored in has_provenance_path\n3. SEARCH LinkedIn for additional profile data\n4. CREATE PersonWebClaim for each extracted fact\n5. LINK claims to PersonObservation records\n\n**INTEGRATION WITH PERSONOBSERVATION**\n\nPersonObservation (the PiCo-based staff role record) references\nPersonWebClaim instances via\

     description: "Concrete class for social media posts/content items.\n\n**DEFINITION**:\n\nSocialMediaPost represents a discrete piece of content published on a social media\nplatform. This includes videos, images, text posts, stories, carousels, threads,\nand other content types. Each post is published by a SocialMediaProfile (account/channel).\n\n**CRITICAL: MULTIVALUED POST TYPES**:\n\nA single SocialMediaPost can have **multiple** post types via the `post_types` slot.\nThis reflects the reality that social media content often combines formats:\n\n| Post Example | Primary Type | Secondary Types |\n|--------------|--------------|-----------------|\n| Instagram carousel with videos | CarouselPost | ImagePost, VideoPost |\n| Twitter thread with images | ThreadPost | TextPost, ImagePost |\n| YouTube Live archived as video | LiveStreamPost | VideoPost |\n| Podcast with video recording | AudioPost | VideoPost |\n| Story highlight (saved) | StoryPost\
       \ | ImagePost, VideoPost |\n\n**TYPE ORDERING CONVENTION**:\n- First type in list = primary/dominant format\n- Subsequent types = secondary characteristics\n- Order matters for display and categorization\n\n**CRITICAL: POST vs PROFILE vs PLATFORM**:\n\n| Class | Represents | Example | Cardinality |\n|-------|------------|---------|-------------|\n| SocialMediaPlatformType | Platform category | YouTube | ~25 types |\n| SocialMediaProfile | Account/channel | @rijksmuseum | Thousands |\n| **SocialMediaPost** | Individual content | A video, post | Millions |\n\n**ACTIVITY STREAMS 2.0 ALIGNMENT**:\n\nMaps to `as:Object` from W3C Activity Streams 2.0 vocabulary:\n- as:Object is the base type for content in social media\n- Individual posts may also map to as:Video, as:Image, as:Note based on post_types\n- Enables federation with ActivityPub-based platforms (Mastodon, PeerTube)\n\n**HERITAGE INSTITUTION CONTEXT**:\n\nSocial media content from heritage institutions includes:\n\n1. **Official\

       \ **multiple** SocialMediaPostType values!\nThis is essential because social media content often combines formats:\n\n- A **carousel** contains both images AND videos\n- A **thread** combines text posts with attached images\n- A **live stream** becomes a standard video when archived\n- A **podcast** may also be published as a video recording\n\n**ACTIVITY STREAMS 2.0 ALIGNMENT**:\n\nSocial media content types align with W3C Activity Streams 2.0:\n- `as:Video` - Video content (YouTube, TikTok, Reels)\n- `as:Image` - Image content (Instagram photos, Pinterest pins)\n- `as:Note` - Short text content (Tweets, Toots)\n- `as:Article` - Long-form content (Blog posts, newsletters)\n- `as:Audio` - Audio content (Podcasts, music tracks)\n\nThis enables federation with ActivityPub-based platforms (Mastodon, PeerTube).\n\n**HERITAGE INSTITUTION CONTEXT**:\n\nCultural heritage institutions create diverse content types:\n\n| Content Type | Heritage Use Cases |\n|--------------|-------------------|\n\
       | **Video** | Virtual tours, conservation demos, interviews, lectures |\n| **Image** | Collection highlights, exhibition photos, archival scans |\n| **Short Video** | Behind-the-scenes moments, artifact spotlights |\n| **Text** | Announcements, event info, research updates |\n| **Story** | Ephemeral content for events, openings, daily life |\n| **Live Stream** | Exhibition openings, Q&A sessions, guided tours |\n| **Audio** | Podcasts about collections, audio guides, oral histories |\n| **Thread** | Multi-part narratives, collection deep-dives |\n\n**CATEGORY STRUCTURE**:\n\nPost types are organized into high-level categories:\n\n1. **VIDEO**: Standard video content (YouTube, Vimeo, Facebook Video)\n2. **SHORT_VIDEO**: Short-form video (TikTok, Reels, YouTube Shorts)\n3. **IMAGE**: Static images (Instagram posts, Pinterest pins, Flickr photos)\n4. **TEXT**: Text-based posts (Tweets, Mastodon toots, LinkedIn posts)\n5. **STORY**: Ephemeral content (Instagram Stories, Facebook Stories)\n\

       \ formats (closed caption, subtitles etc.)\n>  use the MediaObject.encodingFormat property.\"\n\n**SUBTITLE vs CAPTION vs TRANSCRIPT**:\n\n| Type | Time-coded | Purpose | Audience |\n|------|------------|---------|----------|\n| Transcript | Optional | Reading, search | Everyone |\n| Subtitle | Required | Language translation | Hearing viewers |\n| Caption (CC) | Required | Accessibility | Deaf/HoH viewers |\n| SDH | Required | Full accessibility | Deaf viewers, noisy environments |\n\n**SDH (Subtitles for Deaf/Hard-of-Hearing)**:\n\nSDH differs from regular subtitles by including:\n- Speaker identification: \"(John) Hello\"\n- Sound effects: \"[door slams]\", \"[music playing]\"\n- Music descriptions: \"\u266A upbeat jazz \u266A\"\n- Emotional cues: \"[laughing]\", \"[whispering]\"\n\n**SUBTITLE FORMATS**:\n\n| Format | Extension | Features | Use Case |\n|--------|-----------|----------|----------|\n| SRT | .srt | Simple, universal | Most video players |\n| VTT | .vtt | W3C standard,\
       \ styling | HTML5 video, web |\n| TTML | .ttml/.dfxp | XML, rich styling | Broadcast, streaming |\n| SBV | .sbv | YouTube native | YouTube uploads |\n| ASS | .ass | Advanced styling | Anime, complex layouts |\n\n**SRT FORMAT EXAMPLE**:\n\n```\n1\n00:00:00,000 --> 00:00:03,500\nWelcome to the Rijksmuseum.\n\n2\n00:00:03,500 --> 00:00:08,200\nToday we'll explore the Night Watch gallery.\n```\n\n**VTT FORMAT EXAMPLE**:\n\n```\nWEBVTT\n\n00:00:00.000 --> 00:00:03.500\nWelcome to the Rijksmuseum.\n\n00:00:03.500 --> 00:00:08.200\nToday we'll explore the Night Watch gallery.\n```\n\n**HERITAGE INSTITUTION CONTEXT**:\n\nSubtitles are critical for heritage video accessibility:\n\n1. **Accessibility Compliance**: WCAG 2.1, Section 508\n2. **Multilingual Access**: Translate for international audiences\n3. **Silent Viewing**: Social media, public displays, quiet spaces\n4. **Search Discovery**: Subtitle text is indexed by platforms\n5. **Preservation**: Text outlasts video format obsolescence\n\
-      \n**YOUTUBE API INTEGRATION**:\n\nSubtitle tracks from YouTube API populate:\n- `has_or_had_format`: Typically VTT or SRT\n- `generation_method`: PLATFORM_PROVIDED or ASR_AUTOMATIC\n- `content_language`: From track language code\n- `is_or_was_created_through`: YouTube auto-caption flag\n\n**SEGMENTS ARE REQUIRED**:\n\nUnlike VideoTranscript where segments are optional, VideoSubtitle\nREQUIRES the `segments` slot to be populated with VideoTimeSegment\nentries that include start_seconds, end_seconds, and segment_text.\n"

       \ SCORES?**\n\nConfidence scores like `0.95` are MEANINGLESS because:\n- There is NO methodology defining what these numbers mean\n- They cannot be verified or reproduced\n- They give false impression of rigor\n- They mask the fact that claims may be fabricated\n\nInstead, we use VERIFIABLE provenance:\n- XPath points to exact location\n- Archived HTML can be inspected\n- Match score is computed, not estimated\n\n**EXTRACTION PIPELINE (4 Stages)**\n\nFollowing the GLAM-NER Unified Entity Annotation Convention v1.7.0:\n\n1. **Entity Recognition** (Stage 1)\n   - Detect named entities in text\n   - Classify by hypernym type (AGT, GRP, TOP, TMP, etc.)\n   - Methods: spaCy NER, transformer models, regex patterns\n\n2. **Layout Analysis** (Stage 2)\n   - Analyze document structure (headers, paragraphs, tables)\n   - Assign DOC hypernym types (DOC.HDR, DOC.PAR, DOC.TBL)\n   - Generate XPath provenance for each claim location\n\n3. **Entity Resolution** (Stage 3)\n   - Disambiguate entity\
-      \ mentions\n   - Merge coreferences and name variants\n   - Produce canonical entity clusters\n\n4. **Entity Linking** (Stage 4)\n   - Link resolved entities to knowledge bases\n   - Connect to Wikidata, ISIL, GeoNames, etc.\n   - Assign link confidence scores\n\n**WORKFLOW**:\n\n1. Archive website using Playwright:\n   `python scripts/fetch_website_playwright.py <entry_number> <url>`\n   \n   This saves: web/{entry_number}/{domain}/rendered.html\n\n2. Add XPath provenance to claims:\n   `python scripts/add_xpath_provenance.py`\n\n3.

-
-
-        Captures reply/response relationships and metrics for threaded discussions
-
-        using CommentReply class for structured representation.
-

-        **RiC-O NAMING** (Rule 39):
-
-
-        Uses "has_or_had_" prefix to indicate temporal relationship - the content
-
-        has replies currently or had replies in the past (e.g., deleted replies).

-        | **Activity Streams** | `as:inReplyTo` (inverse) | Social media replies |
-
-        | **Schema.org** | `schema:comment` | Generic comment relationship |
-
-      - |
-        **MIGRATION NOTE**:
-
-
-        Created from migration of `comment_reply_count` slot per slot_fixes.yaml.
-
-        Replaces simple integer counts with structured reply data.

+        **PURPOSE**:
+        Captures administrative and governance relationships for heritage
+        institutions. Indicates which entity or authority is responsible
+        for the operational management, direction, or oversight of a
+        resource, collection, or organization.
+      - |
+        **RiC-O NAMING** (Rule 39):
+        Uses "is_or_was_administered_by" alias to indicate temporal
+        relationship - administrative responsibility may change over time
+        as organizations restructure or merge.

+        **USAGE**:

+        - Reading room policies (laptops, photography)
+        - Public space rules
+        - Access permissions
+        - Usage rights
+      - |
+        **SEMANTICS**:
+        Uses RiC-O temporal pattern (is_or_was / has_or_had / allows_or_allowed)
+        to capture policies that may change over time.
+        A reading room that "allowed photography" in 2020 may have changed policy by 2025.

+        **ODRL (Open Digital Rights Language)**:
+        ODRL provides a comprehensive model for permissions:
+        - `odrl:permission` - Permission to perform action
+        - `odrl:Permission` - Class for permission rules

+        **ARGUMENTATION SEMANTICS**:
+        In argumentation theory (Toulmin model), claims provide evidence that 
+        WARRANTS (justifies) conclusions. This slot captures the reverse relationship:
+        a conclusion or derived value is BASED ON supporting claims.
+      - |
+        **PROVENANCE TRACKING**:
+        1. Quantity provenance: A claims_count quantity is based on the actual claims
+        2. Assertion support: An assertion about an entity is based on web claims
+        3. Derivation tracking: A computed value is based on source claims
+      - |
+        **EXAMPLE**:
+        ```yaml
+        has_or_had_quantity:
+          quantity_value: 47
+          quantity_type: CLAIM_COUNT
+          has_or_had_provenance:
+            based_on_claim:

+                claim_value: "Director"
+        ```
+      - |
+        **MIGRATION NOTE (2026-01-19)**:
+        Created per slot_fixes.yaml revision for claims_count migration.
+        Enables provenance tracking for claim-based quantities.

+        **PURPOSE**: Establishes a classification relationship where one entity
+        provides typological or categorical information about another entity.
+        This is the inverse perspective of "has type" - here the classifying
+        entity is the subject rather than the classified entity.

+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | CIDOC-CRM | crm:P2i_is_type_of | 1215 | exact | Type classifies entity |
+        | SKOS | skos:broader | 266 | close | Hierarchical broader |

+        | RiC-O | rico:hasRecordSetType | 8966 | related | Record set type |
+      - |
+        **COMMON USE CASES**:
+        - FeaturePlace classifies CustodianPlace (building type classification)
+        - TypeSpecimen classifies Taxon (nomenclatural classification)
+        - HeritageDesignation classifies HeritageSite (protection status)
+      - |
+        **CIDOC-CRM ALIGNMENT**: Maps to crm:P2_has_type / crm:P2i_is_type_of
+        pattern where one entity provides typological information about another.

+    comments:
+      - |
+        **TEMPORAL PATTERN**: Uses RiC-O `isOrWas*` pattern because collections
+        can be transferred between custodians over time. This property captures
+        both current and historical custody relationships.
+      - |
+        **METONYMIC REFERENCE**:
+        This property captures the common metonymic usage where people refer to 
+        a custodian by its collection:
+        - "The Rijksmuseum has a Rembrandt" (has_or_had_collection)
+        - "This painting belongs to the Rijksmuseum" (collection_of)
+      - |
+        **CUSTODY TRANSFER EXAMPLE**:
+        A collection transferred from Library A to Archive B would have:
+        - Historical: collection_of → Library A (with end date)
+        - Current: collection_of → Archive B (with start date)
+      - |
+        **INVERSE**: `has_or_had_collection` (rico:hasOrHadPart)
+        Pattern: If Custodian hasOrHadCollection Collection, then Collection 
+        isOrWasCollectionOf Custodian
+      - |
+        **MIGRATION NOTE (2026-02-03)**:
+        Migrated from is_or_was_collection_of for conciseness.

+        Uses "contains_or_contained" alias following RiC-O temporal naming

+        **MIGRATION**: Renamed from has_or_had_embargo_end_date for conciseness (2026-02-03).
+        The range is `date` because this slot captures the specific date the embargo lifts,
+        not the embargo policy itself (see `has_embargo_reason` for the justification text).
+      - |
+        **MAPPING NOTE**: `dcterms:available` ("Date that the resource became or will become
+        available") is the closest semantic match — an embargo end date is precisely when a
+        resource becomes available. It is close rather than exact because `dcterms:available`
+        does not inherently carry the concept of a preceding restriction/embargo.

+        **PURPOSE**: Records accessibility features of heritage institutions,
+        their facilities, digital resources, and services. Enables users to
+        discover accessible resources and plan visits accordingly.
+      - |
+        **ONTOLOGY ALIGNMENT** (verified against data/ontology/):
+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | Schema.org | schema:accessibilityFeature | 6543 | exact | Content features |
+        | Schema.org | schema:accessMode | 6458 | close | Access modes |
+        | Schema.org | schema:accessModeSufficient | 6479 | close | Sufficient modes |
+        | Schema.org | schema:amenityFeature | 7869 | broad | General features |

+        | Schema.org | schema:accessibilityHazard | 6564 | related | Hazards |
+        | Schema.org | schema:accessibilitySummary | 6585 | related | Summary |
+      - |
+        **TEMPORAL SEMANTICS** (RiC-O Pattern):
+        "has_or_had_accessibility_feature" indicates features may be historical -
+        an institution's accessibility features may change over time.
+      - |
+        **USAGE PATTERNS**:
+        - For physical locations: wheelchair ramps, elevators, accessible restrooms
+        - For digital resources: captions, audio descriptions, screen reader support
+        - For services: sign language interpretation, assistive listening devices
+        - For materials: Braille, large print, tactile exhibits
+      - |
+        **VALUE RECOMMENDATIONS**:
+        Values should ideally be drawn from the W3C Accessibility Discovery
+        Vocabulary (https://www.w3.org/2021/a11y-discov-vocab/latest/).
+        Common values include:
+        - alternativeText, audioDescription, braille, captions
+        - highContrastDisplay, largePrint, signLanguage, tactileGraphic
+        - wheelchairAccessible, hearingLoop, guideDog
+      - |
+        **RANGE NOTES**:
+        Range is `uriorcurie` (Rule 55) to allow controlled vocabulary URIs
+        or custom accessibility feature references. Classes may narrow via
+        slot_usage to specific AccessibilityFeature enums.

+        **PURPOSE**:
+        Captures asset ownership for heritage institutions. Assets are resources
+        with economic value owned or controlled by an organization with the
+        expectation of future benefit. Used for financial reporting and
+        resource management.
+      - |
+        **RiC-O NAMING** (Rule 39):
+        Uses "has_or_had_asset" alias to indicate temporal relationship -
+        an organization has assets currently or had them in the past
+        (assets may be sold, transferred, or written off over time).
+      - |
+        **ONTOLOGY ALIGNMENT** (verified against data/ontology/):
+
+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | **Schema.org** | `schema:owns` | 28732 | close | Ownership of things |
+        | **RiC-O** | `rico:hasOrHadHolder` | 6437 | related | Holder relationship |
+        | **CIDOC-CRM** | `crm:P52_has_current_owner` | - | related | Current owner |
+        | **CIDOC-CRM** | `crm:P51_has_former_or_current_owner` | - | related | Ownership history |
+      - |
+        **FINANCIAL STATEMENT CONTEXT**:
+        Assets = Liabilities + Net Assets (Statement of Financial Position)
+        
+        Used for:
+        - Total assets on balance sheet
+        - Fixed assets (buildings, equipment)
+        - Current assets (cash, receivables)
+        - Intangible assets (intellectual property)
+        - Collection assets (artwork, artifacts)
+      - |
+        **ODRL NOTE**:
+        ODRL defines `odrl:Asset` as a class, not a property. In ODRL, an Asset
+        is "any form of identifiable resource, such as data/information,
+        content/media, applications, or services." This slot captures the
+        relationship of having/owning assets rather than the Asset class itself.

+        **RiC-O PATTERN**: rico:authorizedBy connects an Agent to a Mandate that gives it
+        authority or competencies to act. A charter is conceptually close to a mandate
+        (both define what an agent may do), but a charter is broader — it also defines
+        purpose, privileges, and constitutional structure, not only authorization.
+      - |
+        **TEMPORAL NOTE**: For organizations requiring articles at registration (Dutch stichting, BV, etc.),
+        the articles EXIST BEFORE the organization legally exists. The articles in PRE_EXISTENCE stage
+        cannot be linked from CustodianAdministration because no Administration exists at that point.
+      - |
+        **VERSIONING**: An organization may have multiple versions of articles over time:
+        - Original founding articles (version 1)
+        - Amended articles (versions 2, 3, ...)
+        - Current version (is_current_version = true)

+        |----------|----------|------|---------|-------|

+        **MIGRATION NOTES**:
+        Consolidated from multiple legacy slots (2026-01-26):
+        - `contact_email` → has_email_address
+        - `admin_email` → has_email_address
+        - `email_address` → has_email_address
+      - |
+        **FORMAT NOTES**:
+        - Uses string range with email pattern validation
+        - schema:email preferred over foaf:mbox as it accepts plain strings
+        - foaf:mbox expects mailto: URI format (e.g., mailto:info@museum.nl)
+      - |
+        **TEMPORAL SEMANTICS** (RiC-O Pattern):
+        "has_or_had_email" indicates email addresses may change over time.
+        Historical email addresses can be preserved with temporal qualifiers.

+    comments:
+      - Updated 2026-02-03 with broad_mappings and narrow_mappings
+      - |
+        **PURPOSE**:
+        Generic slot for file format, media type, or encoding standard.
+        Applies to any digital or physical resource where format matters:
+        - Response formats from APIs (JSON, XML, RDF)
+        - File formats for documents (PDF, DOCX, TXT)
+        - Media formats (JPEG, MP3, MP4)
+        - Transcript formats (VTT, SRT, plain text)
+        - Subtitle formats (WebVTT, SRT, etc.)
+      - |
+        **RiC-O NAMING** (Rule 39):
+        Uses "has_or_had_format" alias to indicate temporal relationship -
+        the resource has a format currently or had one in the past (format
+        conversions may occur over time).
+      - |
+        **ONTOLOGY ALIGNMENT** (verified against data/ontology/):
+
+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | **Dublin Core** | `dcterms:format` | 1296-1320 | exact | File format, medium, dimensions |
+        | **Schema.org** | `schema:encodingFormat` | 16697 | exact | MIME type for media objects |
+        | **DC** | `dc:format` | 1315 | broad | Parent property of dcterms:format |
+        | **DCAT** | `dcat:mediaType` | 1330 | narrow | IANA media type (subPropertyOf) |

+        | **Schema.org** | `schema:fileFormat` | 18031 | related | Deprecated, use encodingFormat |
+      - |
+        **RANGE**: `uriorcurie` (Rule 54)
+        Broadened range to accept URI/CURIE references to format specifications.
+        This allows linking to IANA media types, format registries, or internal
+        format classes while resolving OWL ambiguous type warnings.
+      - |
+        **IANA MEDIA TYPES**:
+        Recommended to use IANA media types with the `iana:` prefix.
+        See: https://www.iana.org/assignments/media-types/media-types.xhtml
+        Classes can narrow to specific format enums/classes via slot_usage.

+        dataset distribution access endpoints (Range: DataService). This slot is broader —
+        it covers any interface type including GUIs, APIs, system boundaries, and user

+        - ENTITY_RESOLUTION: 15 distinct individuals identified via face clustering
+        - OBJECT_TRACKING: 15 tracked face instances (may include same person)

-
-      Used for:

-
-      - File formats for documents (PDF, DOCX, TXT)
-
-      - Media formats (JPEG, MP3, MP4)
-
-      - Transcript formats (VTT, SRT, plain text)
-
-      - Subtitle formats (WebVTT, SRT, etc.)
-
-
-      **ONTOLOGY ALIGNMENT**:
-
-      - **Primary** (`slot_uri`): `hc:hasOrHadFormat` - Heritage Custodian property
-
-      - **Close**: `dct:format` - Dublin Core format
-
-      - **Close**: `schema:encodingFormat` - Schema.org encoding format
-
-
-      **Range**: `uriorcurie` (Rule 54)
-
-      Broadened range to accept URI/CURIE references to format specifications.
-
-      This allows linking to IANA media types, format registries, or internal
-
-      format classes while resolving OWL ambiguous type warnings.

-
-      Classes can narrow to specific format enums/classes via slot_usage.

-      **TEMPORAL SEMANTICS** (RiC-O style):
-
-      The "has_or_had" naming indicates that ranges can change over time:
-
-      - Funding limits adjusted annually

-
-

-      - Currency-aware amounts
-
-      - Comparable across programs
-
-      - Machine-readable for analytics
-
-
-      **CIDOC-CRM Alignment**:

+        Particulate matter measurement is a domain-specific environmental
+        monitoring concept with no direct equivalent in standard ontologies.
+        SOSA provides the general observation/result framework under which
+        such measurements would be modelled, but does not define

+        Common particle size classifications include PM2.5 (fine particles
+        ≤2.5 µm) and PM10 (coarse particles ≤10 µm). Heritage institutions
+        typically target PM2.5 levels below 10 µg/m³ for sensitive collections.

+      - Updated 2026-02-03 with verified ontology mappings and translations
+      - |
+        **PURPOSE**: Assigns roles to agents within organizational structures,
+        activities, or creative endeavors. Consolidated from multiple legacy
+        role slots for consistency.
+      - |
+        **ONTOLOGY ALIGNMENT** (verified against data/ontology/):
+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | W3C Org | org:role | 623 | exact | Membership role |
+        | PROV-O | prov:hadRole | 676 | close | Activity role |
+        | Schema.org | schema:roleName | 33901 | close | Creative role |
+        | W3C Org | org:roleProperty | 580 | broad | Meta-property |
+        | Schema.org | schema:jobTitle | 23787 | narrow | Job title |
+      - |
+        **TEMPORAL SEMANTICS** (RiC-O Pattern):
+        "has_or_had_role" indicates roles may be historical - an entity's
+        role may change over time within an organization.
+      - |
+        **USAGE PATTERNS**:
+        - For authors: role in creating a work (AUTHOR, EDITOR, TRANSLATOR)
+        - For agents: role in an activity or event
+        - For participants: role in a project or organization
+        - For members: role in organizational membership
+      - |
+        **MIGRATION NOTES** (2026-01-16):
+        Consolidated from:
+        - `author_role` → has_role
+        - `agent_role` → has_role
+        - `participant_role` → has_role
+      - |
+        **RANGE NOTES**:
+        Range is `uriorcurie` (Rule 55) to allow enum values or Role class
+        references. Classes may narrow via slot_usage to specific Role enums.

+        **TEMPORAL SEMANTICS** (RiC-O style):
+        The "has_or_had" naming indicates that time interval associations can change:
+        - Update frequencies may be revised
+        - Approval times may change with policy updates
+        - Reporting periods may vary
+        - Durations of media content
+      - |
+        **USE CASES**:
+        - Update frequency: How often data is refreshed (e.g., P7D for weekly)
+        - Approval time: Expected processing duration
+        - Reporting period: Time period for metrics/revenue
+        - Media duration: Length of video/audio content
+      - |
+        **ISO 8601 DURATION FORMAT**:
+        - P = period designator (required)
+        - nY = years, nM = months, nD = days
+        - T = time designator (before time components)
+        - nH = hours, nM = minutes, nS = seconds

+    comments:
+      - Updated 2026-02-03 with verified ontology mappings and translations
+      - |
+        **PURPOSE**:
+        Generic slot for token-related data following RiC-O temporal naming
+        convention. Primarily used for LLM (Large Language Model) token counts
+        in AI/ML processing contexts.
+      - |
+        **ONTOLOGY ALIGNMENT** (verified against data/ontology/):
+        | Ontology | Property | Line | Mapping | Notes |
+        |----------|----------|------|---------|-------|
+        | Schema.org | schema:value | 39461-39492 | close | QuantitativeValue value |
+        | PROV-O | prov:value | 1055-1064 | close | Direct entity value |
+        | SOSA | sosa:hasSimpleResult | 377-379 | related | Observation result |
+      - |
+        **RiC-O NAMING** (Rule 39):
+        Uses "has_or_had_token" alias to indicate temporal relationship -
+        token counts are associated with specific processing events.
+      - |
+        **MIGRATION NOTES** (2026-01-17):
+        Consolidated from:
+        - `cached_token` → has_token
+        - `completion_token` → has_token
+        - `prompt_token` → has_token
+        Use slot_usage in classes to specialize range and semantics.
+      - |
+        **LLM TOKEN TYPES**:
+        - **Prompt tokens**: Input tokens sent to the model
+        - **Completion tokens**: Output tokens generated by the model
+        - **Cached tokens**: Tokens cached for reuse (efficiency optimization)
+        - **Total tokens**: Sum of prompt and completion tokens
+      - |
+        **RANGE NOTES**:
+        Range is `uriorcurie` (Rule 55) to allow references to Token class
+        instances that capture the count, type, and context. Classes may
+        narrow via slot_usage to specific Token enums or integer values.

+        ETIC PERSPECTIVE: This slot captures how an entity is classified from
+        the outside — by researchers, institutions, or classification systems.
+        This contrasts with identify_as, which captures emic (insider)
+        self-identification.
+      - >-
+        EMIC VS ETIC: This is a standard anthropological/social science
+        distinction. Emic = insider perspective (self-identification); Etic =
+        outsider perspective (observer classification). Both are valid and
+        important in heritage contexts.
+      - >-
+        GLAM EXAMPLES: A community self-identifies as "indigenous peoples of
+        the Pacific Northwest" (emic/identify_as), while researchers classify
+        them as "Coast Salish cultural group" (etic/identified_as). An
+        institution self-describes as a "community archive" (emic/identify_as),
+        while a classification system identifies it as a "special collections
+        repository" (etic/identified_as).
+      - >-
+        POWER DYNAMICS: Etic classifications may reflect power imbalances.
+        Heritage practitioners should be aware that externally imposed
+        categories may not align with how communities or entities see
+        themselves.

+        EMIC PERSPECTIVE: This slot captures how an entity defines itself from
+        the inside — the subject is the authority on their own identity. This
+        contrasts with identified_as, which captures etic (outsider)
+        classification.
+      - >-
+        SELF-AUTHORITY: As Schema.org notes for pronouns, "the person concerned
+        is the best authority as pronouns are a critical part of personal
+        identity and expression."
+      - >-
+        SCOPE: Emic self-identification encompasses pronoun preferences (e.g.,
+        she/her, they/them, ze/zir), cultural identity (e.g., "indigenous
+        peoples of the Pacific Northwest"), institutional self-description
+        (e.g., "community archive"), religious or spiritual identity, and any
+        other form of self-classification.
+      - >-
+        LINGUISTIC DIVERSITY: Many languages use gender-neutral pronouns by
+        default (e.g., Malay/Indonesian "dia", Finnish "hän", Turkish "o",
+        Hungarian "ő", Persian "او"). In these languages, pronouns do not
+        indicate gender identity.
+      - >-
+        HISTORICAL RECORDS: Historical sources may not have self-identification
+        as a concept. Leave empty rather than assuming.

+# and Latin) and a single script may be used for multiple languages (e.g.,

+      - |
+        **DESIGN RATIONALE**:
+        This is a GENERIC hierarchical slot for modeling containment/inclusion relationships. 
+        Use when a parent entity encompasses child entities.
+      - |
+        **COMMON USE CASES**:
+        - FunctionType hierarchy (e.g., "Administrative" includes "Finance", "HR")
+        - Organizational unit hierarchy
+        - Collection hierarchy
+        - Record Set aggregation

-    description: 'Initial letter(s) of given name(s), each followed by a period.
-
-
-      An initial is the first letter of a person''s given name, or sometimes
-
-      a combination of letters. Use this property to record initials
-
-      separately from (or in addition to) the full given name.
-
-
-      Format: Each initial should be followed by a period (dot).
-
-
-      Use cases:
-
-      1. Record initials alongside known given name
-
-      2. Record initials when full given name is unknown
-
-      3. Capture unusual abbreviation patterns from historical sources
-
-
-      Examples from PNV specification:
-
-
-      Example 1: "Peter R. de Vries"
-
-      - initials: "P.R."
-
-      - given_name: "Peter R."
-
-
-      Example 2: "C.Joh. Kieviet"
-
-      - initials: "C.Joh." (unusual abbreviation format)
-
-      - OR given_name: "C.Joh." (alternative approach)
-
-
-      Example 3: "H.A.F.M.O. (Hans) van Mierlo"
-
-      - initials: "H.A.F.M.O."
-
-      - given_name: "Hans"
-
-
-      If only initials are known (not the full given name), use this property.
-
-      The given_name property may also contain the initials as a fallback
-
-      when no other representation is available.
-
-
-      Note: Store initials exactly as they appear in the source, including
-
-      unusual formatting patterns like "C.Joh." for historical accuracy.

-
-
-      | Ontology | Property | Usage |

-
-      | **Activity Streams** | `as:Like` | Social appreciation activity |
-
-      | **Schema.org** | `schema:interactionStatistic` | Engagement metrics |
-
-
-      **MIGRATION NOTE**:
-
-
-      Created from migration of `comment_like_count` slot per slot_fixes.yaml.

-      - IoT device lifecycle management
-
-      - Equipment retirement tracking

-
-
-      **Temporal Semantics** (RiC-O Pattern):
-
-      The "isOrWas" naming follows RiC-O convention indicating this
-
-      equivalence may be historical - concepts may diverge over time.
-
-
-      **Ontological Alignment**:
-
-      - **Primary** (`slot_uri`): `hc:isOrWasEquivalentTo` - our ObjectProperty
-
-      - **Maps to**: `skos:exactMatch` - SKOS exact match for semantic equivalence
-
-      - **Related**: `owl:sameAs` - OWL identity (stronger claim)
-
-      - **Related**: `schema:sameAs` - Schema.org identity
-
-
-      Note: slot_uri changed from skos:exactMatch to hc:isOrWasEquivalentTo
-
-      to resolve OWL ambiguous type warning when classes override range
-
-      to class types (e.g., WikiDataIdentifier).
-
-
-      **Range**: `Any` (2026-01-16) - Allows string values and class instances.
-
-
-      **Distinction from is_or_was_related_to**:
-
-      - `is_or_was_equivalent_to`: Semantic identity (same concept)
-
-      - `is_or_was_related_to`: Associative (related but distinct)
-
-
-      **Use Case**:
-
-      Links a heritage custodian type or concept to its Wikidata equivalent.
-
-      Example: Our "Museum" type is equivalent to Wikidata Q33506.
-
-
-      **Cardinality**:

-      Multivalued - an entity may have equivalences in multiple systems.

-    description: 'Classification indicating entity is an instance of a type/class.
-
-
-      **Temporal Semantics** (RiC-O Pattern):
-
-      The "isOrWas" naming follows RiC-O convention indicating this
-
-      classification may be historical - entities may change type over time.
-
-
-      **Ontological Alignment**:
-
-      - **Primary** (`slot_uri`): `hc:isOrWasInstanceOf` - our ObjectProperty
-
-      - **Maps to**: `rdf:type` - RDF type assertion
-
-      - **Exact**: `wdt:P31` - Wikidata "instance of" property
-
-      - **Related**: `schema:additionalType` - Schema.org additional type
-
-
-      Note: slot_uri changed from rdf:type to hc:isOrWasInstanceOf
-
-      to resolve OWL ambiguous type warning when classes override range
-
-      to class types (e.g., WikiDataEntry).
-
-
-      **Distinction from other relationships**:
-
-      - `is_or_was_instance_of`: This entity IS A [type] (classification)
-
-      - `is_or_was_equivalent_to`: This entity EQUALS [concept] (equivalence)
-
-      - `is_or_was_related_to`: This entity RELATES TO [concept] (association)
-
-
-      **Use Cases**:
-
-      - Heritage custodian classified as Wikidata type (Q33506 museum)
-
-      - Building classified as architectural type
-
-      - Collection classified as collection type
-
-
-      **Heritage Example**:
-
-      Rijksmuseum (Q190804) is_or_was_instance_of museum (Q33506)
-
-
-      **Cardinality**:

+      - |
+        **RiC-O NAMING** (Rule 39):
+        Uses "is_or_was_listed_in" alias following RiC-O temporal naming
+        pattern - indicates current or historical listing relationship.
+        Entities may be added to or removed from regulatory lists over time.
+      - |
+        **COMMON USE CASES**:
+        - CITES appendix listings for endangered species specimens
+        - IUCN Red List categorizations for species
+        - National heritage register listings for buildings/sites
+        - UNESCO World Heritage Site designations
+        - Protected species schedules
+        - Museum collection catalogs
+        - Archive finding aids
+      - |
+        **STRUCTURED LISTING PATTERN**:
+        For detailed listings with dates and authorities, use with a
+        Listing class that captures:
+        - listing_type: Type of listing (e.g., CITESAppendix, IUCNRedList)
+        - listing_value: Specific category (e.g., APPENDIX_I, ENDANGERED)
+        - listing_date: Date of listing
+        - listing_authority: Authority that made the listing
+      - |
+        **RANGE NOTES**:
+        Range is `uriorcurie` (Rule 55) to allow references to Register/Catalog
+        URIs or internal Listing class instances. Classes may narrow via
+        slot_usage to specific Register enums or Listing classes.

-      **TRUE when institution maintains**:
-
-      - Live animals in enclosures, exhibits, or aquariums
-
-      - Living plants in gardens, greenhouses, or conservatories
-
-      - Active growth, breeding, or cultivation programs
-

-
-      - Only preserved specimens (taxidermy, dried plants, pickled animals)
-
-      - No active husbandry or horticultural programs
-
-      - Static displays without living organisms
-

-
-      When institutions maintain BOTH living and preserved collections:
-
-      - Natural history museums with live insect colonies (TRUE for living aspect)
-
-      - Botanical gardens with herbarium collections (TRUE for living aspect)
-
-      - Zoos with taxidermy educational displays (TRUE - living is primary)
-
-
-      **Examples**:
-
-      - Artis (zoo): TRUE - Living animal collection with active care
-
-      - Hortus Leiden: TRUE - Living plant collection in greenhouses
-
-      - Naturalis (natural history museum): FALSE - Preserved specimens only
-

-
-      **IMPORTANT DISTINCTION FROM deceased**:
-
-      - `deceased`: Natural death or death from any cause
-
-      - `martyred`: Death specifically due to conflict, persecution, or violence
-
-
-      A person can be both `deceased: true` and `martyred: true` if they died as a martyr.
-
-      A person with `martyred: true` implies `deceased: true`.
-
-
-      **Historical Context**:
-
-      This slot is particularly relevant for documenting:
-
-      - Heritage workers killed during armed conflicts
-
-      - Information professionals targeted for their work
-
-      - Cultural heritage workers killed while protecting collections
-
-      - Librarians, archivists, and museum staff killed in attacks on institutions
-
-
-      **Example - Gaza 2023-2024**:
-
-      Librarians with Palestine documented heritage workers killed during Israeli
-
-      military operations in Gaza, including librarians, archivists, and journalists.
-
-
-      **Wikidata Alignment**:
-
-      Uses P1196 (manner of death) concept for semantic alignment.
-
-      Martyrdom is a specific manner of death requiring documentation.
-
-
-      **Provenance**:
-
-      When setting `martyred: true`, also provide:
-
-      - `date_of_death` (TimeSpan) with temporal bounds

-
-  - EN 16893:2018 (Medium sensitivity): <150,000 lux-hours/year

-
-  - **Goals**: Specific measurable objectives
-
-  - **Values**: Guiding principles
-
-  - **Motto**: Memorable phrases/slogans

-
-  - XPath/CSS selector for verification
-
-  - Content hash for integrity
-
-  - Archive links for long-term access

-
-      **Temporal Semantics** (RiC-O Pattern):
-
-      The "offersOrOffered" naming follows RiC-O convention indicating this relationship
-
-      may be historical - access conditions change over time.
-
-
-      **Ontological Alignment**:
-
-      - **Primary** (`slot_uri`): `schema:publicAccess` - Schema.org public access flag
-
-      - **Close**: `dcterms:accessRights` - Dublin Core access rights
-
-      - **Related**: `schema:isAccessibleForFree` - accessibility information
-
-
-      **Usage**:
-
-      - Collection access: Policies for accessing heritage collections
-
-      - Research access: Conditions for scholarly research use
-
-      - Public access: General public visiting policies
-
-      - Digital access: Online collection availability
-
-
-      **Pattern**:
-
-      Uses Access class to capture structured access information including
-
-      access types, conditions, restrictions, and temporal applicability.
-
-
-      **Range**: `uriorcurie` (Rule 55) - broadened for flexibility.

-    - This is THE identifying property for Person entities. All other properties and relationships connect through this hub identifier.
-    - The path component after /person/ is a lowercased, hyphenated slug derived from the person's preferred name, with optional disambiguators.
-    - Unlike custodian GHCID, person_id does not embed geographic or type codes since persons are mobile and may work at multiple institutions.

-
-      - **Oral tradition**: Recipe knowledge passed verbally master-to-apprentice
-
-      - **Handwritten records**: Historic brewing logs, perfume formulas, recipe books
-
-      - **Apprenticeship**: Hands-on training, direct demonstration, embodied learning
-
-      - **Production continuity**: Unbroken chain of production across generations
-
-      - **Archival collections**: Historic recipe manuscripts, ingredient inventories
-
-      - **Sensory training**: Developing taste/smell expertise (sommeliers, perfumers)
-
-      - **Material culture**: Preservation of traditional tools, vessels, equipment
-
-      - **Protected designation**: PDO/PGI/TSG geographic/traditional labels
-
-
-      Preservation methods ensure intangible knowledge survives.
-
-
-      Examples:
-
-      - "Oral tradition among monks, Handwritten brewing logs, Apprenticeship"
-
-      - "Historic perfume formula archives, Apprentice perfumer training, Nose development"
-
-      - "Family recipe manuscripts, Direct demonstration, Protected Gouda PDO status"

+      or aggregate during a deaccessioning or part-removal activity. Each value

+      out of the custodian's holdings. In CIDOC-CRM terms this corresponds to
+      the target of a P113 removed relationship within an E80 Part Removal
+      event, which explicitly covers deaccessioning objects from an

+        - Custodial responsibility for archival holdings
+        - Formal accountability for cultural property
+      - |
+        **RELATIONSHIP TO TOOI**:
