Mapping between the Dublin Core Abstract Model and the TMDM

Dublin Core is the one of the most used metadata vocabularies. Although it is heavily used in RDF, XML and HTML, this vocabulary is defined independently of any particular encoding syntax. The Dublin Core Metadata Initiative recommends the DCMI Abstract Model (DCAM) as metamodel for the usage of the DC vocabulary. This information model should provide a clear understanding of the kinds of description which are encoded and should facilitate the development of better mappings and cross-syntax translations. For enabling the desired Topic Maps encoding guideline this talk proposes a mapping between the DCAM and the TMDM, as information model of Topic Maps. Having this mapping, DCAM instances can be serialized as topic maps and topic maps using DC vocabulary can be deserialized into DCAM instances. Due to the different terminological expressivity, an isomorphic mapping between DCAM and TMDM is not possible. As consequence, two directed mappings are introduced.
