Implementation of a fully client-side SHACL validation playground. Supports a wide variety of RDF serializations.

Zazuko SHACL Playground

You want to use SHACL shapes to validate RDF-based data but find it hard to go back and forth in your IDE? Are you unsure if the rules even make sense and are applied to your data? Stop worrying and use our SHACL playground!

SHACL playground allows you to define Data Shapes according to the W3C Shapes Constraint Language (SHACL) and test them against sample data.

The implementation of the validation is 100% in JavaScript and thus 100% client-side. We provide an instance of our validator at https://shacl-playground.zazuko.com/.

To run it locally, install the dependencies with npm i, then either start a webpack dev server with npm run --workspace 'packages/app' start and access it at http://localhost:8080, or create a production build with npm run --workspace 'packages/app' build and serve the created dist directory, e.g. with nginx.

To run it using docker, create an image with docker build -t shacl-playground ., then run it using docker run -p 80:80 shacl-playground and access it at http://localhost/.

It is built on our JavaScript-based SHACL library.

Contributions & feedback are very welcome! Enjoy & happy SHACL.

shacl-playground's Issues

@base directive gets lost

When switching between formats (e.g. from turtle to json-ld and back) the @base directive gets lost.

shacl:maxCount "n"^^xsd:integer;

When testing such a constraint in a shape I always get ": More than n values".

Is this supported: shacl:maxCount "n"^^xsd:integer;?

sh:targetNode not working?

Given following shapes and data graphs:

Shapes Graph	Data Graph
@prefix ex: <http://example.org/ns#> . @prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix sh: <http://www.w3.org/ns/shacl#> . @prefix foaf: <http://xmlns.com/foaf/0.1/> . ex:PersonShape a sh:NodeShape ; sh:targetNode ex:Alice ; sh:property [ sh:path foaf:mbox ; sh:minCount 1 ; sh:maxCount 1 ; ] .	@prefix rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#> . @prefix ex: <http://example.org/ns#> . @prefix foaf: <http://xmlns.com/foaf/0.1/> . # invalid, foaf:mbox is missing ex:Alice a ex:Person . # valid, not focus node of ex:PersonShape ex:Bob a ex:Person .

I would have expected to get a validation result for ex:Alice as e.g. provided by shacl.org/playground, however none is returned:

(fwiw, I found this possibly related issue: zazuko/rdf-validate-shacl#59)

Turtle serialization: booleans in collections

When trying

<a> <b> ( true ) .

I get the following error message:

this._dc_factory.boolean is not a function

---

when I trying booleans alone such as:

<a> <b> true .

or lists such as:

<a> <b> ( "Arnold" ) .

No error is thrown

shacl-playground validation doesn't show nested errors

example case:

• https://s.zazuko.com/VLDoy4

result:

• validation result: error (as expected)
• however not all the messages are displayed

expected result:

• show all the validation messages
