triplification using 2 methods

RML

vs

JSON2RDF + SPARQL construct

goals

this is not a performance test. this an ease and capabilities of mapping comparison.

input

the input json is characters.json

output

see

• rml/out.ttl
• json2rdf_and_sparql/out.ttl

notes

• RML required a preprocessing stage and quite a big mapping file (rml/mapping.rml.ttl) (though the mapping is expressed in triples (which is nice)).

• JSON2RDF + SPARQL was much easier than i expected it to be and it did not make superflous triples like RML did.

  • It turns out that JSON2RDF isn't needed either. You can turn json into jsonld (that is almost identical to the output of JSON2RDF) by injectecting some @context into the json. I'll update the repo with that alternative soon.
