[oslc-core] Links to PLM-related Work on RDF (OWL) Mappings

[michael.loeffler at gm.com]

Hi All,

Here are some links I feel could be very useful in our efforts, especially 
to define the Core properties and their RDF/XML representations that will 
be needed by the ALM-PLM workgroup:

S-Ten Project - This seems to be very applicable. I know many of the 
participants, they have been doing this work for a number of years, there 
is a fairly large body of knowledge around how to use RDF/XML OWL to 
represent STEP data. The main site is http://www.s-ten.net/, pay 
particular attention to the Ontologies page at 
http://www.s-ten.net/ontologies, at least Identifier and Version, probably 
a number of others. The other very interesting sections are in their Tools 
section, especially Semantic REST Database (SRDB) 
http://www.s-ten.net/tools/srdb, and SemanticSTEP Viewer 
http://www.s-ten.net/tools/semanticstep-viewer.

OntoSTEP - In another related activity, NIST has been working in parallel 
on the same approach (there is much cross communication in the STEP 
community). OntoSTEP http://www.nist.gov/mel/msid/ontostep.cfm, has a 
plugin to Protege OWL editor that will convert STEP EXPRESS schemas and 
part 21 datasets to OWL RDF/XML. The publication at 
http://www.nist.gov/manuscript-publication-search.cfm?pub_id=901544 gives 
a good technical discussion of the approach and the relationship to S-Ten 
and other efforts.

There are numerous references in the papers cited above that provide great 
background on the PLM world and how it's evolved. I'll follow with some 
more focused attention on the specific concepts that I think need to be in 
a Core properties set to support interoperability.
