which collectively are referred to as "the Submission". We request the Submission be known as the Shape Expressions Submission.

Abstract

Shape Expressions is an abstract syntax and semantics for defining constrain the properties, types and cardinality of nodes in RDF graphs. This can be itself be represented in RDF, and as such extends the Resource Shapes RDF vocabulary. An isomorphic text syntax provides a terse and intuitive presentation of Shape Expressions.

Suggested action

The RDF Validation Workshop, held in September 2013, ended with consensus on the need for

  1. Declarative definition of the structure of a graph for validation and description.
  2. Extensible to address specialized use cases.
  3. A mechanism to associate descriptions with data.

We suggest that the Consortium proceeds with the creation of such a Working Group and uses this Submission and Resource Shapes as a starting point.
