+
+### 🚨 Type Compatibility Rule
+
+**Classes map to classes, properties map to properties.** Never mix types in mappings.
+
+| Your Element | Valid Mapping Target |
+|--------------|---------------------|
+| Class | Class (owl:Class, rdfs:Class) |
+| Slot | Property (owl:ObjectProperty, owl:DatatypeProperty, rdf:Property) |
+
+❌ **WRONG**:
+```yaml
+# AccessApplication is a CLASS, schema:Action is a CLASS - but Action is BROADER
+AccessApplication:
+  exact_mappings:
+    - schema:Action  # WRONG: Action is a hypernym, not equivalent
+```
+
+✅ **CORRECT**:
+```yaml
+AccessApplication:
+  broad_mappings:
+    - schema:Action  # CORRECT: Action is the broader category
+```
+
+### Common Hypernyms That Are NEVER Exact Mappings
+
+These terms are always BROADER than your specific class - never use them as `exact_mappings`:
+
+| Hypernym | What It Means | Use Instead |
+|----------|---------------|-------------|
+| `schema:Action` | Any action | `broad_mappings` |
+| `schema:Organization` | Any organization | `broad_mappings` |
+| `schema:Thing` | Anything at all | `broad_mappings` |
+| `schema:PropertyValue` | Any property value | `broad_mappings` |
+| `schema:Permit` | Any permit | `broad_mappings` |
+| `prov:Activity` | Any activity | `broad_mappings` |
+| `prov:Entity` | Any entity | `broad_mappings` |
+| `skos:Concept` | Any concept | `broad_mappings` |
+| `crm:E55_Type` | Any type classification | `broad_mappings` |
+| `crm:E42_Identifier` | Any identifier | `broad_mappings` |
+| `rico:Identifier` | Any identifier | `broad_mappings` |
+| `dcat:DataService` | Any data service | `broad_mappings` |
+
 ### Common Violations to Avoid

 ❌ **WRONG**:
@ -47,8 +97,46 @@ SocialMovement:
    - schema:Organization # CORRECT
 ```

+❌ **WRONG**:
+```yaml
+AccessApplication:
+  exact_mappings:

+```
+
+✅ **CORRECT**:
+```yaml
+AccessApplication:
+  broad_mappings:
+    - schema:Action  # CORRECT: Action is the broader category
+```
+
+### How to Determine Mapping Type
+
+Ask these questions:
+
+1. **Is it the SAME thing?** → `exact_mappings`
+   - "Could I swap these two terms in any context without changing meaning?"
+   - If NO, it's not an exact mapping
+
+2. **Is the external term a PARENT category?** → `broad_mappings`
+   - "Is my class a TYPE OF the external term?"
+   - Example: AccessApplication IS-A Action
+
+3. **Is the external term a CHILD category?** → `narrow_mappings`
+   - "Is the external term a TYPE OF my class?"
+   - Example: Library IS-A Organization (so Organization has narrow_mapping to Library)
+
+4. **Is it similar but not hierarchical?** → `close_mappings`
+   - "Related but not equivalent or hierarchical"
+
+5. **Is there some other relationship?** → `related_mappings`
+   - "Connected in some way"
+
 ### Verification Checklist

 - [ ] Does the `exact_mapping` represent the **exact same scope**?
- [ ] If the external term is a generic parent class (e.g., `Type`, `Concept`, `Entity`), move it to `broad_mappings`.
- [ ] If the external term is a specific instance or subclass, check `narrow_mappings`.
+- [ ] Is the external term a generic parent class (e.g., `Type`, `Concept`, `Entity`, `Action`, `Activity`, `Organization`)? → Move to `broad_mappings`
+- [ ] Is the external term a specific instance or subclass? → Check `narrow_mappings`
+- [ ] Is the external term the same type (class→class, property→property)?
+- [ ] Would swapping the terms change the meaning? If yes, not an `exact_mapping`

+# Wikidata Mapping Discovery Rule
+
+## Rule: Use Wikidata MCP to Discover and Verify Mappings Carefully
+
+When adding Wikidata mappings to class files, you MUST verify the semantic meaning and relationship before adding any mapping.
+
+### 🚨 CRITICAL: Always Verify Before Adding
+
+**NEVER add a Wikidata QID without verifying:**
+1. What the entity actually IS (not just the label)
+2. That it's the SAME TYPE as your class (organization→organization, NOT organization→building)
+3. That the semantic relationship makes sense
+
+### Workflow
+
+#### Step 1: VERIFY Existing Mappings First
+
+Before trusting any existing mapping, verify it:
+
+```sparql
+SELECT ?item ?itemLabel ?itemDescription WHERE {
+  VALUES ?item { wd:Q22075301 wd:Q1643722 wd:Q185583 }
+  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
+}
+```
+
+**Example of WRONG mappings found in codebase:**
+| QID | Label | Was Mapped To | WHY WRONG |
+|-----|-------|---------------|-----------|
+| Q22075301 | textile artwork | FacultyPaperCollection | Not related at all! |
+| Q1643722 | building in Vienna | UniversityAdministrativeFonds | Not an archival concept! |
+| Q185583 | candy | AcademicStudentRecordSeries | Completely unrelated! |
+
+#### Step 2: Search for Candidates
+
+Search for relevant Wikidata entities by keyword or hierarchy:
+
+```sparql
+SELECT ?item ?itemLabel ?itemDescription WHERE {
+  ?item wdt:P279 wd:Q166118 .  # subclasses of "archives"
+  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
+}
+```
+
+#### Step 3: VERIFY Each Candidate
+
+For EVERY candidate found, verify:
+1. **Read the description** - does it match your class?
+2. **Check instance of (P31)** - is it the same type?
+3. **Check subclass of (P279)** - is it in a relevant hierarchy?
+
+```sparql
+SELECT ?item ?itemLabel ?itemDescription ?instanceLabel ?subclassLabel WHERE {
+  VALUES ?item { wd:Q9388534 }
+  OPTIONAL { ?item wdt:P31 ?instance. }
+  OPTIONAL { ?item wdt:P279 ?subclass. }
+  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
+}
+```
+
+#### Step 4: Confirm Semantic Relationship
+
+Ask: **Would a domain expert agree this mapping makes sense?**
+
+| Your Class | Wikidata Entity | Verdict |
+|------------|-----------------|---------|
+| FacultyPaperCollection | Q22075301 (textile artwork) | ❌ NO - completely unrelated |
+| CampusDocumentationCollection | Q9388534 (archival collection) | ✅ YES - semantically related |
+| AcademicArchive | Q27032435 (academic archive) | ✅ YES - exact match |
+
+### Type Compatibility Rules
+
+| Your Class Type | Valid Wikidata Types | Invalid Wikidata Types |
+|-----------------|---------------------|------------------------|
+| Organization | organization, institution | building, person, artwork |
+| Record Set Type | collection, fonds, series | building, candy, textile |
+| Event | activity, occurrence | organization, place |
+| Type/Category | type, concept, class | specific instances |
+
+### Common Mistakes to Avoid
+
+❌ **WRONG: Adding any QID found in search without verification**
+```
+"Found Q1643722 in search results, adding it as mapping"
+→ Result: Mapping a "building in Vienna" to "UniversityAdministrativeFonds"
+```
+
+✅ **CORRECT: Verify description and type before adding**
+```
+1. Search finds Q1643722
+2. Verify: Q1643722 = "building in Vienna, Austria"
+3. Check: Is a building related to "UniversityAdministrativeFonds"?
+4. Decision: NO - do not add this mapping
+```
+
+### When to Add Wikidata Mappings
+
+Add Wikidata mappings ONLY when:
+- [ ] You verified the entity's label AND description
+- [ ] The entity is the same type as your class
+- [ ] The semantic relationship is clear (exact, broader, narrower, related)
+- [ ] A domain expert would agree the mapping makes sense
+
+### When NOT to Add Wikidata Mappings
+
+Do NOT add Wikidata mappings when:
+- You only searched but didn't verify the description
+- The entity type doesn't match (e.g., building vs. organization)
+- The relationship is unclear or forced
+- You're just trying to "fill in" mappings
+
+### Mapping Categories
+
+| Category | Wikidata Property | When to Use |
+|----------|-------------------|-------------|
+| `exact_mappings` | - | Same semantic meaning (rare!) |
+| `close_mappings` | - | Similar but not identical |
+| `broad_mappings` | P279 (subclass of) | Wikidata entity is BROADER |
+| `narrow_mappings` | inverse of P279 | Wikidata entity is NARROWER |
+| `related_mappings` | - | Non-hierarchical but semantically related |
+
+### Checklist
+
+For each Wikidata mapping:
+
+- [ ] Verified entity label matches expected meaning
+- [ ] Verified entity description confirms semantic fit
+- [ ] Entity type is compatible with class type
+- [ ] Mapping category (exact/close/broad/narrow/related) is correct
+- [ ] A domain expert would agree this makes sense
+
+### Example: Proper Verification for FacultyPaperCollection
+
+**Step 1: What are we looking for?**
+- Personal papers of faculty members
+- Academic archives
+- Manuscript collections
+
+**Step 2: Search**
+```sparql
+SELECT ?item ?itemLabel ?itemDescription WHERE {
+  ?item ?prop ?value .
+  ?value bif:contains "'personal papers' OR 'faculty papers'" .
+  SERVICE wikibase:label { bd:serviceParam wikibase:language "en". }
+} LIMIT 10
+```
+
+**Step 3: Verify candidates**
+- If no exact match found → DO NOT add a wrong mapping
+- Better to have NO Wikidata mapping than a WRONG one
+
+**Step 4: Decision**
+- No exact Wikidata match for "FacultyPaperCollection"
+- Keep ontology mappings only (rico-rst:Fonds, bf:Archival)
+- Do NOT add unrelated QIDs like Q22075301 (textile artwork!)
+
+### Integration with Other Rules
+
+This rule complements:
+- **mapping-specificity-hypernym-rule.md**: Rules for choosing mapping type
+- **wikidata-mapping-verification-rule.md**: Rules for verifying QIDs exist
+- **verified-ontology-mapping-requirements.md**: General ontology verification

-      CIDOC-CRM E8 Acquisition models the transfer of legal ownership rights.
-
-      **Key properties**: - `temporal_extent`: When the acquisition occurred (TimeSpan
-      with fuzzy boundaries for historical items) - `acquisition_method`: How the
-      item was acquired (field collection, purchase, donation, etc.) - `acquisition_source`:
-      From whom/where acquired (collector, dealer, previous owner, field location)
-      - `acquisition_agent`: Who performed the acquisition (collector, curator, institution)
-
-      **Darwin Core alignment**: For biological specimens: - `temporal_extent` replaces
-      `dwc:eventDate` (collection date) - `acquisition_source` can capture `dwc:locality`
-      and `dwc:recordedBy`
-
-      **Use cases**: - Museum object provenance (purchase from dealer, 1923) - Biological
-      specimen collection (field collection, Amazon basin, 1750s) - Archival transfer
-      (transferred from ministry archives, 2001) - Art donation (donated by artist''s
