Zusammenfassung
A broad range of different semantic technologies have been developed and standardized over the last years, but browsing on web sites rarely takes advantage of them although semantic descriptions can be supplied with RDF. We see one reason for it in the missing linkage between this data and the page content being presented to the user. Consequently, the underlying data cannot be addressed via an interaction with the visual representation. Recently, a new formalism—RDFa—that seeks to close this gap has been standardized by the W3C. It defines some additional attributes for XHTML and a mapping from the at- tribute values and the document content into RDF triples. An important feature in our con- text is the usage of selected text parts for literal properties and hence the explicit linkage between the human- and the machine-readable representations. In contrast to the mapping, the handling of this linkage is left open in the reference specification.
