I can't support the current deliverables, at least as I understand them.

The first deliverable indicates that the working group is supposed to be 
producing an RDF vocabulary for shapes without defining what shapes are or how 
they are to be used.  Either that or the first deliverable is simply an RDF 
vocabulary for some existing definition of shapes, which seems even stranger.

The second deliverable uses considerably different language, as if the two 
products cover quite different situations.   This does not sound like a good 
idea to me.

There is no recommendation track deliverable for the meaning of 

The current draft charter is also tilted away from the kind of RDF validation 
that is done with respect to RDFS classes, particularly in the scope section. 
  This is particularly strange as there has been quite a bit of discussion as 
to how class-based validation relates to shapes.  I would have expected the 
scope to have been widened to cover the goals of class-based validation of RDF 
graphs.  I also don't see what RDF shapes have to say to the description of 
query interfaces.

I do not think that the charter is ready.
