(An ontology is essentially a formal description of objects and their interrelationships.) The MIT/LCS has begun to define <A href="http://www.daml.org/">DAML</A> (DARPA Agent Markup Language), a language for expressing ontologies. Although DAML is very much a work in progress, real work can be done now with RDF Schemas, see the section on Redfoot below.</P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.xml.com/pub/a/2000/11/01/semanticweb/index.html?page=2"><P>The hardest problem in this area is not the infrastructure, but the actual ontologies themselves. Until an industry-wide ontology exists for, say , vehicle parts, there is a limit to the utility of the SW in the auto manufacturing industry. Organizations such as the <A href="http://www.purl.org/dc/">Dublin Core Metadata Initiative</A> have been developing such vocabularies for some time now, and they've made progress both in terms of the ontologies themselves and also tools to manage and maintain them.</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/925E2CF5-4F5E-4FAD-BA0F-A25E012AD2FD/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
