owl2shacl

A CLI tool that tries to convert simple OWL ontologies into SHACL shapes. OWL ontologies define logical relationships. SHACL shapes define a data scheme, and allow to validate data against them. Strictly speaking, as these are different things, such a conversion is thus illegal/wrong in the ideological/theoretical sense. Thus this tool is not generally applicable, but only under the circumstance, that the OWL ontology is actually written as a data specification - if it is understood as a kind of distributed database schema, rather then for logical inference. Not only that, but it also has to conform to certain, very narrow rules, and only a few basic properties are translated into SHACL; the rest is ignored.

Supported OWL ontologies

Roughly speaking, this tool supports a 25% subset of OWL Lite, plus some third party properties.

More specifically:

• OWL Lite
  • Class (Thing, Nothing)
  • `rdfs:subClassOf
  • rdf:Property
  • rdfs:subPropertyOf
  • rdfs:domain
  • rdfs:range
  • Individual
  • equivalentClass
  • equivalentProperty
  • sameAs
  • differentFrom
  • AllDifferent
  • distinctMembers
  • ObjectProperty
  • DatatypeProperty
  • inverseOf
  • TransitiveProperty
  • SymmetricProperty
  • FunctionalProperty
  • InverseFunctionalProperty
  • Restriction
  • onProperty
  • allValuesFrom
  • someValuesFrom
  • minCardinality
  • maxCardinality
  • cardinality
  • Ontology
  • imports
  • intersectionOf
  • versionInfo
  • priorVersion
  • backwardCompatibleWith
  • incompatibleWith
  • DeprecatedClass
  • DeprecatedProperty
  • rdfs:label
  • rdfs:comment
  • rdfs:seeAlso
  • rdfs:isDefinedBy
  • AnnotationProperty
  • OntologyProperty
  • xsd datatypes
• others
  • domainIncludes
    • schema:domainIncludes
    • dcam:domainIncludes
    • dcid:domainIncludes
    • rdfs:domain + owl:unionOf
  • rangeIncludes
    • schema:rangeIncludes
    • dcam:rangeIncludes
    • `dcid:rangeIncludes
    • rdfs:range + owl:unionOf

How to compile

You need to install Rust(lang) and Cargo.

Then get the whole repo plus git sub-modules with:

git clone --recurse-submodules https://codeberg.org/elevont/owl2shacl.git
cd owl2shacl

Then you can run:

cargo build --release

If all goes well, the executable can be found at target/release/owl2shacl.

Get the tool

As for now, you have two choices:

1. Compile it yourself
2. Download a Linux x86_64 statically linked binary from the releases page
