Proposed change to the charter, section 4. Deliverables, Recommendation Track

The output of the wg is defined by its deliverables. Here is the current 
text [1]

Recommendation Track:
1.      Compact, human readable syntax for expressing constraints on RDF 
graph patterns (aka shapes), suitable for the use cases determined by the 
group. This syntax might be a variation of an existing standard, such as 
templates for SPARQL, or something new, such as ShExC.
2.      An RDF vocabulary, such as Resource Shapes 2.0, for expressing 
these shapes in RDF triples, so they can be stored, queried, analyzed, and 
manipulated with normal RDF tools.
The WG MAY produce a Recommendation for graph normalization.

This text is not acceptable to IBM because of the primary emphasis it 
places on defining a possibly new compact, human readable syntax. I 
believe this concern has been expressed repeatedly by many people on the 
mailing list. Many people have indicated a strong preference for building 
on existing standards. However, we have not seen any corresponding 
modification of the charter. I'd therefore like to propose a strawman 
change to this section of the charter and invite comment. Here is the 
proposed new text:
The WG MUST produce:
1. A high-level RDF vocabulary that expresses commonly occurring 
2. The semantics of the high-level constraints expressed in terms of 
3. An RDF extension mechanism for expressing additional constraints, 
expressed in SPARQL.
The WG MAY produce:
1. A new compact, human readable syntax for expressing constraints with a 
corresponding semantics expressed in SPARQL.
2. A specification for graph normalization.
