Thanks for your proposal Reinhold. I tried to avoid expanded identifiers used in XMI (I'm aware of this effort). Doing so I was struggling with the missing global identity of aggregated classes in UML. But, I agree, since there is already a more or less standard way of naming things, it is appropriate to reuse it. So I updated the UML/RDF vocabulary. The revised version (2000-04-22) is accessible under http://www-db.stanford.edu/~melnik/rdf/uml/ Note that using XMI for "Web-enabled" encoding of UML has severe limitations. XMI is based on a frozen DTD. So you cannot append arbitrary attributes to existing classes, associations, instances etc. Sergey Reinhold Klapsing wrote: > > Hi Sergey, > > you might be interested in the XML Metadata Interchange (XMI) > to adopt the names for your RDF-classes and -properties describing > an UML model. > > - http://www.oasis-open.org/cover/xmi.html > - ftp://ftp.omg.org/pub/docs/ad/98-10-16.txt > > Reinhold > > <cit> > XMI 1.1 RTF Main revised document - OMG XMI 1.1 RTF. 25 October 1999. > OMG XMI v. 1.1: Revisions and Recommendations Summary.
