Thanks for the feedback. > could you fix the HyperDAML code to recognize ".html", ".asp", ".jsp" in > the resource and simply redirect the web browser there? Unfortunately, it isn't quite that simple. HTML may have DAML embedded in it, file suffixes are optional with most servers, and tracking file suffixes is a never-ending proposition. The right longer-term solution is probably for HyperDAML to act based on the MIME type, but we don't yet have a DAML MIME type and the new W3C RDF Core Working Group is just beginning to tackle that issue for RDF (with suggestions like text/xml+rdf). It would also be helpful if RDF had a means of distinguishing references to other RDF instances from arbitrary resources. With DAML+OIL (March 2001), it may be preferable to use xsd:uriReference DatatypeProperties for such foreign references. > Or HyperDAML could parse the linked resource document looking for the string > > <?xml version='1.0' encoding='ISO-8859-1'?> I like this idea! Unfortunately, many DAML/RDF documents don't use this, including http://www.daml.org/2001/03/daml+oil (we should fix this) http://www.w3.org/2000/01/rdf-schema A reasonable hack might be to only generate hyperdaml links for references containing #fragments, but that doesn't help in your case.
