The information represented in a topic map, expressed in one of the XML interchange syntaxes for topic maps can, at some level of detail, be translated into information that is expressed in one of the XML interchange syntaxes for RDF information. The translated information can then be used in the context of RDF applications that would otherwise not be able to use it.
The author has developed an online XTM to RDF translator, ‘XTM2RDF Translator,’ which uses XSLT-based technology to translate any topic map document expressed in the XTM syntax into RDF abbreviated syntax. The translation process respects the TMPM4 parsing model for XTM. XTM2RDF supports traversals within and among RDF and XTM documents. RDF applications can thus be XTM-enabled. Also, RDF graph viewers can be used to view ‘topic map graphs’ a la the TMPM4 parsing model.
