-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 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. peter On 06/02/2015 06:44 PM, Arnaud Le Hors wrote: > Hi Peter, Thanks for volunteering to help but what do you mean by "a > SHACL specification document or fragment"?
