[oslc-core] Buglet in Core 2.0 - non-exemplary(?) use of Change Request

[John Arwe]

Stumbled across the excerpt below at [1]:  note the phrase "content body 
is a change request resource definition ".  Unless "change request" is 
intended to be a term of art that I don't recognize (if so, just a 
different problem), this could easily be read to mean than an OSLC CM 2.0 
Change Request [2] is the only input allowed to pre-fill the creation 
dialog ... which I'm pretty sure was not the intent.  I don't get much 
more satisfaction thinking of it as a (HTTP) PATCH document, especially in 
this context where POST is explicitly called out.
I'm guessing that a change like the following is needed, so here's a 
strawman proposal:

from: whose content body is a change request resource definition     to
to:   whose entity  body is an incomplete    resource representation to

We might then be faulted for not defining what an "incomplete" resource 
is, and for failing to say what the relationship is between the incomplete 
resource and the (ultimately) newly created resource is.  I could answer 
that with the following strawman (to be inserted where convenient in 
context):
The incomplete resource representation provides a template for how to 
pre-fill the creation form.  It is simply a set of triples whose 
predicates and corresponding object values provide initial values for the 
resource being created via the form.



Prefilling Creation Dialogs 
Service providers MAY support receiving a POST request whose content body 
is a change request resource definition to the Creation Dialog URI to 
retrieve a URI that represents the embedded page to be used. Service 
providers MUST respond with a response status of 201 (Created) with the 
response header Location whose value is the URI to request the newly 
created form.
