An experimental command line tool for interactively matching SKOS concepts to Wikidata.
% pip install -r requirements.txt
% ./skos_wikidata.py example/uat.rdf
This will look for concepts in your RDF file and ask you to match them up against Wikidata entities. As assertions are added to the graph they will be serialized back to the RDF file. So you can quit at any time and have your work saved.
By default skos:exactMatch assertions will be created between your SKOS
concepts and Wikidata. If you would like to be more nuanced and to also use
skos:closeMatch, skos:broadMatch, skos:narrowMatch and skos:relatedMatch
you will will want to:
% ./skos_wikidata.py --relations-prompt example/uat.rdf
Also your SKOS may use SKOSXL for labels, in which case you'll need to tell skos_wikidata.py to query the data a bit differently:
% ./skos_wikidata.py --skosxl example/uat.rdf
Because it loads the graph for the entire concept scheme into memory and writes it back to disk after every mapping assertion this may not be practical for super large SKOS concept schemes. But for thousands and tens of thousands of concepts it's not so bad. YMMV. Optimizations could be made (not saving all the time, etc) so give it a try and let me know!
Oh, and here is a video demonstration of the tool in action.
