rdf-to-ts --help
Usage: dist [options] <pattern>

Generate TypeScript from RDF


  -V, --version          output the version number
  -p, --prefixes         output prefixes
  -i, --iris             output IRIs
  -l, --literals         output literals
  -c, --classes          output classes
  -d, --default-exports  output default exports. Can only be used in combination with other flags
  -D, --debug            output debug information
  -h, --help             output usage information


The following command will output types for all classes explicitly defined in the ontology, as well as an object containing the prefixes and IRIs used by the ontology.

rdf-to-ts example.ttl > example.ts

How does it work?


In order to construct types for the classes in the ontology we need the following pieces of information for each type:

  • owl:Class: What is the name of the class?
  • rdfs:subClassOf: What are its super-classes?
  • rdfs:domain, rdfs:range, owl:FunctionalProperty: Property names, types and pluralities.
