Validata: An online tool for testing RDF data conformance

Validata is an online web application for validating an RDF document against a set of constraints. This is useful for data exchange applications or ensuring conformance of an RDF dataset against a community agreed standard. Constraints are expressed as a Shape Expression (ShEx) schema.

The Validata code is available from https://github.com/HW-SWeL/Validata. Existing deployments are available for:
