4. The Challenge: Maintaining Relationships

5. I: Basic Authorship and Linking

7. Linking to SNAC

8. Linking to VIAF

9. Add/delete
Bound to
conventionDeclaration

10. This is a hack! This isn't what conventionDeclaration means,
but EAC lacks the appropriate declaration

11. Linking to DBpedia

13. Create Stub
Create relationship to
existing EAC-CPF record

28. Next Steps
 Finish form: Represent all EAC-CPF elements and attributes
 Test for scalability
 Improve documentation
 Improve public interface, especially searching and browsing
 Follow evolving best practices in RDF/linked open data (for
archival authorities, SNAP ontology, CIDOC-CRM)
 Incorporate social network graph visualization
