output ontologies as JSONLD

[VladimirAlexiev]

Use tricks from https://github.com/gs1/EPCIS/tree/master/Ontology#conversion-to-jsonld. make jsonld invokes commands like this

ttl2jsonld CGMES-NC/ttl/SteadyStateInstruction-AP-Voc-RDFS2020.ttl | \
  jsonld compact -c file://CIM-ontology-context.jsonld > CGMES-NC/jsonld/SteadyStateInstruction-AP-Voc-RDFS2020.jsonld

• [ ] https://github.com/Sveino/Inst4CIM-KG/issues/110

Then I check for JSON-LD irregularities with a command like this;

grep -h '       "@' */*/*.jsonld|perl -pe 's{^ +}{}' |sort|uniq -c

Here are the exceptions, with issue listed:

I also check whether all URLs are properly shortened

grep -h '"http' */*/*.jsonld|sort|uniq -c|less

Breakdown of problems:

• [ ] https://github.com/Sveino/Inst4CIM-KG/issues/69 There are 2 dm prefixes but we can only declare one in JSONLD

  @prefix dm:           <http://iec.ch/TC57/61970-552/DifferenceModel/1#> .
  @prefix dm:           <https://ap-voc.cim4.eu/DatasetMetadata#> .

• [x] I had cim:UnitMultiplier.none 1.0 (decimal), now fixed to 1E0 (double)

This is largely done, see https://github.com/Sveino/Inst4CIM-KG/tree/develop/rdfs-improved/CGMES/jsonld.

• Leaving it open and assigning to Svein and Chavdar for the subtasks (checkboxes) above.
• Of them, https://github.com/Sveino/Inst4CIM-KG/issues/110 is most important

They are all posted as separate issues, so we may as well close this one.
