Including Topic Maps in the Ontology Definition Meta-model

Topic maps have many similarities to RDF but are distinct historically, technically and in their main intended purpose. They started in the early 90s and were published as an ISO standard in 2000 while RDF started in the late 90’s and was published as a W3C Recommendation in 2004. Each has it’s own constraint language, data model, and set of syntaxes. Topic Maps define a knowledge representation language on par with RDF. While the ODM RFP does not require Topic Maps, they represent an additional, independently developed alternative URI based ontology language to the W3C’s RDF and RDFS/OWL that strengthens the ODM.
