Shape Repository For SkoHub
This is a repository for SHACL shapes used in SkoHub modules.
Shapes
skos.shacl.ttl
this is just a first draft, comments are very welcome
This shape is inspired by and borrows heavily from the SKOS-XL shape definition from EU Vocabularies.
Most adjustments were made regarding correcting syntax and pulling out the SPARQL-based constraints into dedicated shapes. At least with Apache Jena SHACL and pySHACL I got lots of different error messages when trying to use the shape as it is.
If you take our template repo as a starting point the validation against this shape is already built in.
Check with Apache Jena SHACL
To use this shape with Apache Jena SHACL validate your file with shacl validate --shapes skos.shacl.ttl --data YOUR-DATA.ttl
Check with Docker
To validate with the help of a docker container, you can run the script scripts/validate-skos:
./scripts/validate-skos YOUR_SKOS_FILE_TTL
Call with -h or without arguments to list options.
Checked Constraints
All class and property definitions from the SKOS reference are added in the test files. All valid and invalid consistency examples are added to the test files.
Integrity conditions are checked by the skos.shacl.ttl shape.
Tests
There is some basis test functionality provided to test the shape. Currently there are not many tests provided, but the general idea is as follows:
- build a small valid Concept Scheme for a node shape
- build a small invalid Concept Scheme for a node shape
- put these in the appropriate folders under
test/ - check if it works with
scripts/test.sh
These tests are also run on every push via GitHub Actions.
It is very basic, but works like this:
- all files in the valid folder are run against the shape. If the validation script exits with
exit 1it returns an error - all files in the invalid folder are run against the shape. If the validation script exits with
exit 0it returns an error
Feel free to suggest improvements or add more tests!
