New JSON-LD output
Hi,
I have been working on improving the JSON-LD output provided by Stanbol. The
output is now much cleaner by implementing the latest JSON-LD 1.0 spec. A
major improvement is that the implementation tries to avoid CURIEs
automatically. Below is a snippet from an output of the Stanbol Enhancer.
Web developers who are not interested in the details, can just overlook the
@context part and get the data they want from each @subject by using simple
short property names.
Best,
- Fabian

Re: New JSON-LD output

Hi Fabian,
That's good news.
I don't know if and how the json-ld library could be added to apache
commons. For now I've opened CLEREZZA-642 for adding the code there. A patch
would be very welcome :)

Hi,

Hmm may be you're right and this could be improved. I will have closer look
tomorrow. Thanks!

Looks great. Thanks Fabian.
However I don't understand why the @context has both a line for the
ontology prefix:
"db-ont:": "http://dbpedia.org/ontology/",
and then specific type shortnames such as:
"Artist": "http://dbpedia.org/ontology/Artist",
"MusicalArtist": "http://dbpedia.org/ontology/MusicalArtist",
"Person": "http://dbpedia.org/ontology/Person",
And then in the payload:
"@type": [
"dbp-ont:Artist",
"dbp-ont:MusicalArtist",
"dbp-ont:Person",
...
],
Either we use shortnames for types or we use the prefix notation
without polluting the context whith type shortnames.
