What We Accomplished

Phase 5: Validation Framework ✅

Delivered:

1. ✅ Validation script (scripts/validate_temporal_consistency.py, 534 lines)

   • 5 validation rules implemented
   • CLI with detailed error reporting
   • Exit codes for CI/CD integration

2. ✅ Test suite (tests/test_temporal_validation.py, 455 lines)

   • 19 test cases
   • 100% pass rate (19/19)
   • Valid/invalid/warning scenarios
   • Integration test (merger scenario)

3. ✅ Documentation (docs/VALIDATION_RULES.md, 650+ lines)

   • Complete rule definitions
   • 15+ valid/invalid examples
   • Usage guide and workflow
   • SHACL preview

4. ✅ Completion documentation (VALIDATION_FRAMEWORK_COMPLETE_20251122.md)

---

Validation Rules Implemented

1. Collection-Unit Temporal Consistency (Phase 4)

   • Collection custody dates must fit within managing unit validity

2. Collection-Unit Bidirectional Relationships (Phase 4)

   • Forward/reverse relationships must be synchronized

3. Custody Transfer Continuity (Phase 4)

   • No gaps or overlaps in collection custody

4. Staff-Unit Temporal Consistency (Phase 3)

   • Staff role dates must fit within unit validity

5. Staff-Unit Bidirectional Relationships (Phase 3)

   • Forward/reverse staff-unit relationships must match

Next Steps

Phase 6: SPARQL Query Library (Upcoming)

Goal: Document common query patterns for organizational data

File: docs/SPARQL_QUERIES_ORGANIZATIONAL.md

Query Categories:

1. Staff queries (Phase 3)
2. Collection queries (Phase 4)
3. Combined staff + collections queries
4. Organizational change impact queries
5. Validation queries (SPARQL equivalents)

Estimated Time: 45-60 minutes

---

Future Phases

Phase 7: SHACL Shapes (RDF triple store validation)
Phase 8: LinkML Schema Constraints (embed validation in schema)
Phase 9: Real-World Data Integration (apply to heritage institution data)

---

Session Metrics

Time Breakdown:

• Validation script: ~20 minutes
• Test suite: ~15 minutes
• Documentation: ~15 minutes
• Completion docs: ~10 minutes

Total: ~60 minutes

Productivity:

• 27 lines/minute (1,639 lines ÷ 60 min)
• 3.2 tests/minute (19 tests ÷ 6 min test writing time)

Handoff for Next Agent

Phase 6 Focus

Goal: SPARQL Query Library

Prerequisites: ✅ All complete

• Schema v0.7.0 finalized
• Test instances available (Phase 4)
• Validation rules documented (Phase 5)

Files to Create:

1. docs/SPARQL_QUERIES_ORGANIZATIONAL.md (SPARQL query patterns)
2. Examples demonstrating queries against test data

Approach:

1. Convert validation rules to SPARQL WHERE clauses
2. Document staff queries (find curators, list unit members)
3. Document collection queries (find managing unit, list collections)
4. Document combined queries (curator + collection cross-reference)
5. Document organizational change queries (track custody transfers)
