Dear Peter, all,

  indeed, 
https://github.com/cimiano/tbx2rdf/blob/master/ontology/tbx.owlis an old 
version of the ontology that is not maintained anymore.

On the versioning information: If some entries are revised or deleted, 
one could add Transactions modelled Activities (in the sense of the 
Provenance Ontology) including information that this is a 
DeletionActivity. One could add also a "MakeObsolete" Activity that 
relates two terminological concepts. However, we have not thought too 
deep about this. It could be interesting to extend the guidelines along 
these lines. We would be happy to look into this. Can you send some 
examples of what you want to represent?

The guidelines show an example how to represent transactions as PROV 
Activities.

Of course, some status triples could be added directly to the 
terminological concepts, but that does not replace making explicit the 
history and provenance, e.g. who deleted the entry and why, who said 
that some terminology concept makes another one obsolete etc.

The question is whether to do versioning *in* RDF or outside RDF: 
depending on the use case, there are different answers I assume.

If one does versioning *in* RDF, then the terminological concept is 
still there, in spite of having being deleted... there would be a 
property added to mark it as deleted (something like tomb marker) and a 
transaction describing the deletion activity. Is this the way you would 
like to go?

Just for curiosity: why were you surprised to find these guidelines? 
This comments surprises me ;-)

Greetings,

Philipp
