[Oslc-recon] Common IT Resource Type vocabulary

[Martin P Pain]

I have some questions about the Common IT Resource Type vocabulary that is 
under the OSLC Recon WG.

(Firstly, the link from the "Resource definitions" part of the spec to the 
vocab document is broken. This seems to be a common problem on the OSLC 
wiki. Also, the File:reconciliation.xml  link at the top of the vocab page 
itself is broken.)

Both the wiki page and the TURTLE document contain RDF instances such as 
"crtv:ThreadPool", "crtv:WebSphereServer", "crtv:J2EEServer", and 
"crtv:MQQueue". In the TURTLE document these are under a comment that 
identifies them as "constants".

What are these constants/instances for?  I presume that they (apart from 
crtv:NULL) are to demonstrate which class should be used for each type of 
resource that they are named after (e.g. that J"EE servers should be of 
type "crtv:SoftwareServer" and MQ Queues should be of type 
"crtv:SoftwareModule"). However I cannot find this documented anywhere.

If that is the case, then it seems to me that they shouldn't be in the 
same file with the official crtv vocab. Even if they are terms that have 
been used by systems while the vocabulary has been developed (at this 
stage it looks like they should not be used as the object of an rdf:type 
triple as they are not themselves of type rdfs:Class) then would they be 
better in a separate vocab file? If they aren't used as terms anywhere, 
then just stating these suggested mappings on a wiki page somewhere should 
suffice? Perhaps they could form part of the "OSLC Reconciliation Version 
2.0 Appendix A: Samples" appendix (incidentally also either a broken link 
or not created yet).

(The context for my looking at this vocab is that it might be useful to 
reuse in some scenarios we're looking at for v3 of the OSLC Automation 
spec, but those extra terms in the vocabulary document were confusing. 
Especially as in the wiki page they're mixed in with the rest of the 
vocabulary as it's all in alphabetical order, unlike in the TURTLE 
document where the constants are separated out.)

I appreciate that this is still a work in progress, but there's a number 
of things that could be done here to aid the consumability of these pages 
to someone coming to them anew, even if familiar with other OSLC domains.
