Overview

rudof is a library that implements Shape Expressions, SHACL, DCTAP and other technologies in the RDF ecosystem. The library is implemented in Rust and it also provides Python bindings.

rudof can be used as a command line tool or can be embedded as a library using cargo. It can be used to validate RDF data represented with different syntaxes like Turtle, NTriples, to name a few. As well as RDF data available through SPARQL endpoints like Wikidata. rudof can also be used to convert between different RDF data validation technologies (like ShEx, SHACL, or DCTAP), and to generate UML like visualizations and HTML views.
