Re: editing SHACL specification document or fragment

Shapes Constraint Language (SHACL) http://w3c.github.io/data-shapes/shacl/
is written like a user manual - information that tells users how SHACL works
in enough detail so that they can write SHACL.

However, the document does not do a good job of nailing down just what SHACL
is, i.e., the formal underpinnings of just what inputs are valid SHACL and
what the definition of correct behaviour is.  There is some of this
information in various parts of the document, particularly Appendix B.
SPARQL Definitions of the SHACL
Templateshttp://w3c.github.io/data-shapes/shacl/#sparql-template-defs, but
the rest of it is fragmented, incomplete, and in places ill-founded.

I think that there needs to be a document, or a portion of a document, that
gathers together all the information needed to completely and unambiguously
specify SHACL and thus to correctly implement SHACL.  Most users of SHACL
would not need to use this information, but the working group does need to
produce it.
