ShEx.ex

CI Hex.pm

An implementation of the ShEx specification in Elixir.

It allows to run validations specified in the Shape Expressions language (ShEx) on RDF graphs.

Shape Expressions (ShEx) is a language for describing RDF graph structures. A ShEx schema prescribes conditions that RDF data graphs must meet in order to be considered "conformant": which subjects, predicates, and objects may appear in a given graph, in what combinations and with what cardinalities and datatypes.

-- Shape Expressions (ShEx) Primer

The validation of larger amounts of nodes is done in parallel.

The API documentation can be found here. For a guide and more information about ShEx.ex and it's related projects, go to https://rdf-elixir.dev.

Limitations

  • the following ShEx features are not implemented yet:
    • invalid shape expression references in negations are not checked
    • imports
    • external shapes
    • annotations
    • semantic actions
  • greedy matching
  • non-ascii characters in regular expressions are not fully supported yet
