Feedback on UC&R draft abstract

Feedback on: http://w3c.github.io/data-shapes/data-shapes-ucr/#abstract

Has:
"To foster the development of the RDF Data Shapes specification, this
document includes a set of user stories, use cases, and requirements that
motivate a simple read-write Linked Data architecture, based on HTTP access
to web resources that describe their state using RDF. "

which seems like it was copied from the LDP UC&R document, perhaps tweaking
it a bit to be:
"To foster the development of the RDF Data Shapes specification, this
document includes a set of user stories, use cases, scenarios and
requirements that motivate a simple language and semantics for defining
structural constraints on RDF graphs."
or something as that.

I will review the rest at some point later, coming along nicely.

Steve Speicher
