[oslc] Proposal to Finalize a Subset of the OSLC EMS 1.0 Vocabulary

The OSLC Performance Monitoring 2.0 specification [1] depends on a subset 
of the OSLC EMS 1.0 vocabulary [2], which is currently in the Convergence 
phase. The use of these vocabulary terms by OSLC Performance Monitoring 
2.0 provides us with enough implementation experience to recommend that we 
finalize the used subset. The remainder of the vocabulary will remain in 
the Convergence phase until we get similar implementation experience.

Based on discussions with Steve Speicher, we've decided to maintain a 
single namespace for OSLC EMS 1.0, and to allow its terms to be at various 
phases of approval. This approach follows the way that the FOAF vocabulary 
is managed. [3] In FOAF, each term has a "Status", which is a value such 
as "testing", or "stable". FOAF uses the vocabulary vs: "
http://www.w3.org/2003/06/sw-vocab-status/ns#" and the property 
vs:term_status="testing". [4]

I'll use the standard OSLC lifecycle phases: "Scope", "Draft", "Converge", 
"Finalize", and "Final" as the values for vs:term_status. [5]

I have created a wiki page that lists the proposed subset. [6] 

I will also be adding indicators to the OSLC EMS 1.0 vocabulary document 
to clearly define the approval status of each term.  All terms except the 
requested subset will be marked as "Converge". The requested subset will 
be marked as "Finalize". 
Please reply to this list with your comments, concerns, and feedback.
