Embedding RDF in XHTMLMartin Cavanagh, University of Osnabrück AbstractThe presentation explains the problems involved with embedding RDF in XHTML and shows possible solutions. In relation to this the Homepage Generator: Math-Net Meta Maker 2.1 & 2.2 is described. Emdedding RDF directly in XHTML creates problems with most browers - that they parse this RDF object as XHTML and attempt to render it as text in the XHTML document. This means one needs to find an alternative way to store RDF data in a XHTML document. Two current schools of thought on possible solutions which were both implemented at Osnabrück are described in the following: XHTML allows SVG Objects. It is possible to have an SVG object of 0 pixels width and 0 pixels height, while SVG allows RDF code. So the problem is solved? The problem is that the RDF then describes all of the tags - except the SVG tag itself. Discussion after this presentation showed additional problems with this candidate solution. Basically it doesn't allow namespaces to be used dynamically in the RDF fragment - they have to be all previously described in a DTD header (wherethe same problem as with writing RDF directly into XHTML reoccurs. The second possible solution involves creating a link in the XTML document to a valid RDF document. This is one of the currently accepted and common methods for embedding RDF in XHTML, though it comes with the typical problem of every external linking, its lack of presistence.

these two methods of embedding RDF data can be found here: There remains no standard for embedding RDF in XHTML, though many more candidates for the solution are acutally being discussed:
