XML is the conventional, indeed "normative," syntax for writing RDF, but an RDF graph is more than just its encoding as an XML document.<br /><br />That is, just because an application can parse and manipulate XML doesn't mean that it "understands" RDF. (Note that the converse is also false.)Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-5135517.post-1099313911023114352004-11-01T04:58:00.000-08:002004-11-01T04:58:00.000-08:00How does one get a PhD like this?
