Open source implementations:

  • Apache Jena, supports SHACL Core and SHACL SPARQL [1].
  • RDF4J, supports a subset of the SHACL Core [2] [3], including DASH [4].
  • TopQuadrant SHACL API, based on Apache Jena. Supports most features, including SHACL-C, SHACL-AF and SHACL-JS [5].
  • pySHACL, supports most SHACL features as SHACL Core, SHACL Rules and SHACL-JS [6].
  • dotNetRDF SHACL Service, supports SHACL Core [7].

Proprietary implementations:

  • TopBraid EDG, full SHACL support [8].
  • Stardog, supports SHACL Core [9].
  • Ontotext, using RDF4J ShaclSail [10].
  • AllegroGraph [11].

SHACL Playground [12].

A collection of SHACL documentation

Nice collection! I’d also add the zazuko SHACL playground

SHACL has many uses. Most likely focus on graph validation. TopBraid also uses shapes to generate User Interfaces

I have been working on similar, to have web pages and forms describe in SHACL.

See @hydrofoil/shaperone:

And @hydrofoil/roadshow:

FYI, I also implemented the Zazuko’s playground

Another open source implementation of SHACL is SHACL-s in Scala: GitHub - weso/shacl-s: SHACL implementation in Scala

Also, RDFShape (http://rdfshape.weso.es/) is a playground that supports both SHACL and ShEx. In the case of SHACL, it is possible to select 3 engines to validate: SHACL-s, Jena and TopQuandrant’s one so it is possible to compare results between them.
