From: Robb Shecter <shecter@d...> >A week or so ago, someone asked how a piece of RDF can be validated, >analogous to the way that a piece of XML can be validated with a DTD. I >don't think anybody answered this, or I missed the answer. (?) I'm new >to RDF, and don't know the answer, because as I understand it, >validating RDF would mean making sure that the document properly follows >(say) Dublin Core, and DC is defined as a schema, not as a DTD. (?) My impression is that the simple Dublin Core people are primarily interested in making HTML manageable for information discovery. The qualified Dublin Core people are more concerned with using the simple Dublin Core as classes; all the QDC people I have talked to (from ECAI, etc) are more concerned with making a schema for centralized databases, and relatively uninterested in "serialization" issues. This is why the Dublin Core does not have any concrete element sets; sooner or later they will want to distribute the processing, and presumably then they might get around to it. I noticed that HTML 4 has some definite markup for allowing different profiles on the metatags, to support Dublin Core. But the examples of Dublin Core in HTML that the practitioners of it use don't seem to conform. And I have seen examples given of "how to use DC in HTML 3 and HTML4" which give different methods. I don't think there is much awareness that rigorous markup involves more than just defining a field. As far as validating RDF, you might be interested in a little note I wrote "Using XSL to Validate Structured Documents" http://www.ascc.net/xml/en/utf-8resource_index.html You can use XSL to write a very simple validation program that gives nice error messages and works with wrappers or islands.
