AsTMa! Topic Map Processing

Technical Report, by Robert Barta

The AsTMa language family is designed to support authoring, updating, constraining and querying of Topic Maps.

Whenever Topic Maps are authored, they might have to follow a particular structure. In the same way as relational databases are constrained by schemas and XML languages follow constraints (provided by DTDs, XML Schemas, Schematrons, …), Topic Maps can also be constrained by a constraint or a set of constraints. AsTMa! is one AsTMa sub-language which allows to formulate such constraints.

I like the easy but powerful way of merging Topic Maps to extend and combine existing knowledge bases. Thus I see high potential in distributed environments where peer to peer solutions may open the gates to the real Web 3.0.
