[oslc-core] oslc:totalSize Clarification

[Arthur Ryman]

Andy,

Yes, totalCount is repeated. See [1] for a discuss of stable vs unstable 
paging.

+1 for only using totalCount in conjunction with query responses (and also
probably for Arthur's amendment in another e-mail for "thisCount" on a 
page
of the response, but is totalCount repeated on every page???  what happens
with -- I forget the terminology -- queries where the paged results aren't
cached, so the "second page" is different based on when it's retrieved)

It's for queries that this is important; it's not a new concept in this
context.

As pointed out before, the use of totalCount with paging of "other
resources" seems a bit suspect. Do we really need to say that it SHOULD be
the number of property values (triples)? Is this proposed definition
useful? Is there a use case where someone is needing this capability? 
Seems
like we are specing something that doesn't need to be spec'd. Maybe we
should just say that totalCount is used in conjunction with query
responses?
