Semantic Dependencies

This tool converts the node_modules dependencies of an npm project to RDF. Currently this is done by parsing the output of the npm ls command, while in the future we also want to be able to simply parse a given node_modules folder.

Note that this is not the same as the dependencies that can be found in a package.json file! The output will contain the actually installed versions, not the semantic ranges.

Sample output when this is executed on its own folder:

@prefix doap: <http://usefulinc.com/ns/doap#>.
@prefix npm: <https://linkedsoftwaredependencies.org/vocabularies/npm#>.
@prefix doc: <https://www.w3.org/2000/10/swap/pim/doc#>.
