Abstract:
In this paper, we present a multi-temporal RDF data model, which can be used to support RDF(S) light-weight ontology versioning. The data model is equipped with ontology change operations, which are defined in terms of low-level updates acting on RDF triples. As a result, the operational semantics of a complete set of primitive ontology changes has been formalized, taking care of preservation of class/property hierarchies and typing constraints. When used within the transaction template, which has also been introduced, the proposed ontology changes allow knowledge engineers or maintainers of semantics-based Web resources to easily define and manage temporal versions of an RDF(S) ontology.
