What is SemVersion? • RDF-based ontology versioning system • Data management aspects of versioning • Functional aspects of versioning

Functional aspects • Structural diff – Set theoretic difference of two RDF triple sets
• Semantic diff – Language semantics dependent – Structural diff between the schema entailment of two RDFS models

Semantic Versioning Manager • Integration of SemVersion in Protégé • Support for the ontology lifecycle
• Re-using as much as possible the functionalities already offered by Protégé • Deployment as an installation kit

Future directions • SemVersion – – – –
Partial re-design Client-Server architecture Storage: Full versions vs. Diffs Support for temporal queries
• Semantic Versioning Manager – 100% Protégé integration as a back-end
28
Summary • SemVersion – RDF-based ontology versioning system – Separation between data management and functional aspects
• Semantic Versioning Manager – Integration of SemVersion in Protégé
