Semantic data playground: RDF, ShEx, SHACL, etc.

RDFShape

RDFShape is full web application for semantic data analysis and validation where you can toy with...

• RDF conversion between different formats like Turtle and JSON-LD
• RDF validation using ShEx (Shape Expressions) and SHACL (Shapes Constraint Language)
• RDF querying with SPARQL
• RDFS and OWL inference

...among others.

FYI

This is a general repository for explanations and configuration files of RDFShape. If you're searching for detailed instructions or tutorials for the backend or frontend of this tool, head to the linked repositories.

Quick reference

• Maintained by: WESO Research Group

Structure of RDFShape

RDFShape is formed by:

• rdfshape-api: A backend in charge of the operations, which are exposed in the form of a public API
  • Repo
  • Deployment
  • Web docs
• rdfshape-client: A general use-case client
  • Repo
  • Deployment
• wikishape: A wikibase/wikidata oriented client
  • Repo
  • Deployment

Deploying a full RDFShape stack (server & clients)

A template docker-compose file is available in this repository for users to tweak it according to their needs.

If you only require certain services of the RDFShape stack or want to test them out yourself, the Dockerfiles and detailed instructions on how to build/run the Docker images can be found in each module's repository.

Alternatively, you may get yourself a fully operational RDFShape service using our deployed services.

rdfshape's Issues

failure to load an ontology

This ontology fails to load at the playground site, with this error:

The request body was invalid.

It succeeds at WebVOWL.

Check if there has been some change in shape-map url parameter

Eric and me had agreed on using a compatible API for validating...however, looking at this comment, it seems we broke the compatibility using shapeMap instead of shape-map, we should check if we can revert that change without breaking anything...a possible solution could be to just support both.

Multibyte char in response is garbled

In https://rdfshape.herokuapp.com/query, Multibyte char (especially kanji) contains of response text is garbled by wrong encoding.
