Versioning in distributed semantic registries
Christoph Ludwig, Marc Wilhelm Küster, Graham Moore · 2008
Change is a constant (not only) in the Semantic Web. Both instance data and ontologies evolve. These changes are a piecemeal process, morphing from version to version both for conceptualizations / ontologies and for the related instance data / individuals. Individual versions capture valuable information about ontologies and instance data that were valid at a given point in time.
