Folks,

There is a W3C standard (SHACL)[1] in development that would address the 
issue of validation of RDF graphs. The standard itself is, as standards 
tend to be, long and not an easy read. Eric Prud'hommeaux and I (both 
committee members) have created a first draft of a brief reference 
document, in the form of an Abstract Syntax of the core vocabulary of 
the SHACL standard. We welcome any comments or corrections to this 
document, and any suggestions for making it better. The draft is at:

https://www.w3.org/TR/2016/WD-shacl-abstract-syntax-20160825/

Comments should be sent to the mail list at:

However, I will also entertain any discussion that takes place here, 
which feels less formal than posting to a W3C list. Our goal is to make 
SHACL Core as clear as possible for first time users. If this becomes a 
W3C standard, it will probably eventually become available in various 
RDF-related tools.

Thanks,
kc

As announced on the W3C blog[1], the first public working draft of the 
SHACL Core Abstract Syntax[2] has been published by the RDF Data Shapes 
Web Working Group.[3]

"This document defines an abstract syntax for the core SHACL (SHApes 
Constraint Language). It is derived from the SHACL specification and is 
a non-normative version of the content of that specification."

We are soliciting comments (and questions) on this first draft. Please
