[Oslc-pm] perf mon metric categories draft up

[John Arwe]

Julie and I met with the EMS WG chair this week to discuss how we had 
drafted pm:metricQualifier as a categorization mechanism for metrics. 
Based on his feedback we restructured the syntax to eliminate 
pm:metricQualifier and use RDFS subclassing for categorization.  This 
brings it pretty much directly into the same pattern that EMS uses, seems 
no worse in terms of expressivity, and makes the Measure instances smaller 
by moving the categorization "metadata" from the instance to the RDFS.

[1]'s content through the Resource Properties heading is the bulk of the 
new material.  New turtle and RDF on the samples page [2], but it does not 
yet agree with the "equivalent" table above [2].  I did it quick & by hand 
for now, but in short order I'll probably write code to cross-check and/or 
generate chunks of content from the master.... e.g. subclass tree from 
vocab doc, metrics category URIs table from vocab doc, etc.
[3] has updated vocab doc
[4] has updated arch doc
