Transition Request
This is a transition request for one document from the RDF Data Shapes
Working Group <https://www.w3.org/2014/data-shapes/wiki/Main_Page> to
Candidate Recommendation:
Document title, URIs, and estimated publication date
* Shapes Constraint Language (SHACL)
* Latest Published: https://www.w3.org/TR/shacl/
* Editor's Draft: http://w3c.github.io/data-shapes/shacl/
* Staged Draft: Not yet staged
* Desired Publication Date: 2017-03-30
Document Abstract and Status sections
Abstract:
This document defines the SHACL Shapes Constraint Language, a language
for validating RDF graphs against a set of conditions. These conditions
are provided as shapes and other constructs expressed in the form of an
RDF graph. RDF graphs that are used in this manner are called "shapes
graphs" in SHACL and the RDF graphs that are validated against a shapes
graph are called "data graphs". As SHACL shape graphs are used to
validate that data graphs satisfy a set of conditions they can also be
viewed as a description of the data graphs that do satisfy these
conditions. Such descriptions may be used for a variety of purposes
beside validation, including user interface building, code generation
and data integration.

Requirements satisfied
Charter says:
The mission of the RDF Data Shapes Working Group is to produce a
language for defining structural constraints on RDF graphs. In the same
way that SPARQL made it possible to query RDF data, the product of the
RDF Data Shapes WG will enable the definition of graph topologies for
interface specification, code development, and data verification.
The group produced:
* SHACL Use Cases and Requirements
<https://www.w3.org/TR/2015/WD-shacl-ucr-20150414/>
* All requirements have been addressed
* The WG decided to defer the optional topic of a user-friendly
compact syntax to future work, see
https://www.w3.org/2014/data-shapes/wiki/Postponed

Over the life of the WG:
* 72 different people provided comments on the public mailing list
<https://lists.w3.org/Archives/Public/public-rdf-shapes/>.
* 230+ issues were opened and resolved on the W3C issue tracker
<https://www.w3.org/2014/data-shapes/track/issues>
* More recently, 24 issues were opened and resolved on GitHub
<https://github.com/w3c/data-shapes/issues?page=1>, including i18n
comments.
Due to a concern raised by a commenter about possible flaws in the
comment tracking process, the group particularly welcomes during CR the
re-submission of any earlier comments that turn out to have not been
properly addressed. The WG does not know of any such comments.
