Submission Request to W3C: Resource Shape 2.0

Submitted Materials

We, W3C Member(s) IBM, Fujitsu, and Universidad Politécnica de Madrid, hereby submit to the Consortium the following specification, comprising the following document(s) attached hereto:

  1. Resource Shape 2.0

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


This document defines a high-level RDF vocabulary for specifying the shape of RDF resources. The shape of an RDF resource is a description of the set of triples it is expected to contain and the integrity constraints those triples are required to satisfy. Applications of shapes include validating RDF data, documenting RDF APIs, and providing metadata to tools, such as form and query builders, that handle RDF data.

Intellectual Property Statements

Suggested action

The RDF Validation workshop, held in September 2013, showed that:

There was 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.


The participants agreed that there is currently no standard addressing these needs and the W3C should do something about it. The majority of participants agreed that the W3C should create a Working Group to develop a Recommendation that provides a declarative way of expressing a set of basic integrity constraints governing an RDF graph with an extension mechanism to handle more complex scenarios.

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


To help with this work we expect, but do not commit, to be able to provide representatives to participate in the working group.
