Schema Evolution publication categorizer

Ontologies are often seen as basic building blocks for the SemanticWeb,
as they provide a reusable piece of knowledge about a specific domain. However, those
pieces of knowledge are not static, but evolve over time. Domain changes, adaptations
to different tasks, or changes in the conceptualization require modifications of the ontology.
The evolution of ontologies causes operability problems, which will hamper
their effective reuse. A versioning mechanism might help to reduce those problems,
as it will make the relations between different revisions of an ontology explicit. This
paper will discuss the problem of ontology versioning. Inspired by the work done
in database schema versioning and program interface versioning, it will also propose
building blocks for the most important aspects of of a versioning mechanism, i.e., ontology
identification and change specification.
