description: "A web portal that aggregates or provides discovery access to heritage\nmetadata from multiple custodian institutions.\n\n**DEFINITION**:\n\nWebPortal represents AGGREGATION/DISCOVERY portals - platforms that collect\nand expose metadata from multiple heritage institutions. Distinguished from:\n- **DigitalPlatform**: A single custodian's website/online presence\n- **CollectionManagementSystem**: Backend software managing collection data\n\n**KEY CHARACTERISTICS**:\n\n1. **Multi-Institution Aggregation**: Portals aggregate metadata from many institutions\n2. **Discovery Focus**: Primary purpose is search/discovery across collections\n3. **Standardized Metadata**: Use common standards (EDM, Dublin Core, EAD, LIDO)\n4. **Technical Infrastructure**: Provide APIs, OAI-PMH endpoints, SPARQL\n5. **Operated by Networks**: Typically run by EncompassingBody (Network, Consortium)\n\n**RELATIONSHIP ARCHITECTURE**:\n\n```\nEncompassingBody (operator)\n \u2502\n \u2514\u2500\u2500\
\ operates \u2192 WebPortal\n \u2502\n \u251C\u2500\u2500 portal_data_sources \u2190 CollectionManagementSystem[]\n \u2502 (CMS feeds data to portal)\n \u2502\n \u251C\u2500\u2500 exposes_collections \u2192 CustodianCollection[]\n \u2502 (collections discoverable via portal)\n \u2502\n \u2514\u2500\u2500 aggregates_from \u2192 WebPortal[]\n (portal-to-portal aggregation chains)\n```\n\n**AGGREGATION CHAINS**:\n\nSome portals aggregate from other portals, forming chains:\n```\nCMS \u2192 Regional Archive Portal \u2192 National Archive Portal \u2192 Archives Portal Europe\nCMS \u2192 Museum \u2192 Aggregator \u2192 Europeana\n```\n\nUse `aggregates_from` and `aggregated_by` to model these chains.\n\n**PORTAL TYPES** (from WebPortalType\
\ class hierarchy):\n\n- **NATIONAL_AGGREGATOR**: NDE Dataset Register, Deutsche Digitale Bibliothek\n- **REGIONAL_AGGREGATOR**: LEO-BW, Bavarikon\n- **ARCHIVAL_PORTAL**: Archieven.nl, Archives Portal Europe\n- **LIBRARY_UNION_CATALOG**: WorldCat, GBV\n- **MUSEUM_COLLECTION_PORTAL**: Collectie Nederland, Europeana Collections\n- **CROSS_DOMAIN_AGGREGATOR**: Europeana, DPLA\n- **COLONIAL_HERITAGE_PORTAL**: Colonial Collections (NL)\n- **GENEALOGICAL_PORTAL**: OpenArchieven.nl, FamilySearch\n- **LINKED_DATA_HUB**: NDE Termennetwerk, Wikidata\n- **OAI_PMH_HARVESTER**: BASE, OpenAIRE\n\n**EXAMPLES OF DUTCH PORTALS**:\n\n1. **NDE Dataset Register** (datacatalogus.netwerkdigitaalerfgoed.nl)\n - Type: NATIONAL_AGGREGATOR\n - Operator: NDE (NetworkOrganisation)\n - Scope: All Dutch heritage datasets\n \n2. **Archieven.nl** (archieven.nl)\n - Type: ARCHIVAL_PORTAL\n - Operator: KVAN network\n - Data sources: MAIS-Flexis deployments at regional archives\n - Aggregated by: Archives\
\ Portal Europe\n \n3. **OpenArchieven.nl** (openarchieven.nl)\n - Type: GENEALOGICAL_PORTAL\n - Focus: Scanned civil registration, parish records\n - Open access genealogical sources\n \n4. **Collectie Nederland** (collectienederland.nl)\n - Type: MUSEUM_COLLECTION_PORTAL\n - Operator: Rijksdienst voor het Cultureel Erfgoed\n - Aggregates museum objects from Dutch museums\n \n5. **Colonial Collections** (datacatalogus.../group/colonial-collections)\n - Type: COLONIAL_HERITAGE_PORTAL\n - Focus: Colonial history provenance research\n - Part of NDE Dataset Register infrastructure\n\n**EXAMPLES OF GERMAN PORTALS**:\n\n1. **Archivportal-D** (archivportal-d.de)\n - Type: ARCHIVAL_PORTAL\n - Operator: Landesarchiv Baden-W\xFCrttemberg (coordination)\n - National archive finding aid aggregator\n \n2. **Deutsche Digitale Bibliothek** (deutsche-digitale-bibliothek.de)\n - Type: CROSS_DOMAIN_AGGREGATOR\n - German national aggregator for Europeana\n - Cross-domain\
\ (archives, libraries, museums)\n \n3. **LEO-BW** (leo-bw.de)\n - Type: REGIONAL_AGGREGATOR\n - Baden-W\xFCrttemberg regional portal\n \n4. **Bavarikon** (bavarikon.de)\n - Type: REGIONAL_AGGREGATOR\n - Bavaria regional cultural heritage portal\n\n**EXAMPLES OF EUROPEAN/INTERNATIONAL PORTALS**:\n\n1. **Europeana** (europeana.eu)\n - Type: CROSS_DOMAIN_AGGREGATOR\n - Operator: Europeana Foundation (NetworkOrganisation)\n - 50M+ objects from European cultural heritage\n - Aggregates from national aggregators (DDB, Gallica, etc.)\n \n2. **Archives Portal Europe** (archivesportaleurope.net)\n - Type: ARCHIVAL_PORTAL\n - Operator: APEF Foundation\n - European archival finding aids\n - Aggregates from national archive portals\n \n3. **Monasterium.net** (monasterium.net)\n - Type: MONASTIC_HERITAGE_PORTAL\n - Operator: ICARUS (Consortium)\n - Medieval charters and monastic documents\n \n4. **WorldCat** (worldcat.org)\n - Type: LIBRARY_UNION_CATALOG\n\
\ - Operator: OCLC (Cooperative)\n - 500M+ bibliographic records\n\n**ONTOLOGY ALIGNMENT**:\n\n- **EDM** (`edm:Aggregation`): Primary mapping - portal aggregates CHOs\n- **ORE** (`ore:Aggregation`): Object Reuse and Exchange aggregation\n- **Schema.org** (`schema:WebSite` + `schema:DataCatalog`): Web presence + data catalog\n- **DCMI Type** (`dcmitype:Collection`): Collection of metadata records\n\n**LIFECYCLE AND MIGRATION**:\n\nPortals evolve over time:\n- New portals launch\n- Portals merge (use `supersedes_or_superseded`)\n- Portals become legacy but remain accessible\n- Portal scope expands (regional \u2192 national)\n\nTrack status with `portal_status`: ACTIVE, LEGACY, DEPRECATED, MERGED\n"

comments:
- WebPortal is DISTINCT from DigitalPlatform (single custodian website)
- WebPortal AGGREGATES metadata from multiple institutions
- "Portals form aggregation chains: regional \u2192 national \u2192 European"
- Typically operated by EncompassingBody (Network, Consortium)
- Track lifecycle with portal_status and supersedes_or_superseded
- has_policy (was data_license_policy) links to portal's licensing stance (CC0, CC-BY, etc.)
- 'NEW: created_by_project links to Project that built the portal'
- 'NEW: associated_with for organizational relationships beyond operator (migrated from associated_encompassing_bodies)'
- 'NEW: implements_digital_platform links to aggregated DigitalPlatform instances'
- 'NEW: implements_auxiliary_platform links to subordinate AuxiliaryDigitalPlatform instances'
- "FUNDING: For funding relationships, link FundingOrganisation \u2192 Project \u2192 WebPortal (not direct)"
