Semantic Wikis Versioning with BiFröST

One of the powerful and popular tools that are used to support Collaborative Knowledge Engineering are Semantic Wikis. They are easily accessible and provide ACL mechanisms, but they lack a good versioning mechanism. In this paper an extended version of such a mechanism is proposed. Besides elements that appear in every Wiki system, like simple changelog and place for discussion, it incorporates changes ontologies, rich metadata, semantic metrics and reasoning unit tests. All of them are gathered into the form of the provenance graph that can be serialized into Turtle syntax and (automatically) analyzed. First prototype of such a mechanism for Loki wiki called BiFröST was developed.
