Evaluate use of schema.org for organisation data #34

Closed acka47 closed 9 years ago

acka47 commented 10 years ago

As we have to do some tweaking for organisation data in lobid anyway (https://github.com/lobid/lodmill/issues/486, ), we might think about switching to schema.org if it covers all our needs. Whether this is the case will be explored in this ticket.

This would have consequences on efforts on aligning RDF representation in lobid and ISIL registry (https://github.com/lobid/lodmill/issues/181), though.

This is the current JSON-LD context. It lists all 29 RDF properties currently used in lobid-organisations.

The following example nearly includes all properties from the JSON-LD context, except dcterms:subject and skos:prefLabel (is this used anywhere in lobid-organisations?).

Let's see how one could express the example above with schema.org:

@prefix schema: <http://schema.org/> .

      a       schema:Library ; ## See https://github.com/lobid/lodmill/issues/509.

              <http://dbpedia.org/resource/Staatsbibliothek_zu_Berlin> ;
      schema:openingHoursSpecification
              [ schema:description
                        "Mo-Fr 9.00-21.00, Sa 10.00-19.00"
              ] ;

Re: dcterms:subject and skos:prefLabel: subjects are declared as dc-elements (NOT dc-terms). It's configured in morph https://github.com/lobid/lodmill/blob/master/lodmill-rd/src/main/resources/morph_zdb-isil-file-pica2ld.xml and you can search some data with curl -XGET -L 'http://quaoar1.hbz-nrw.de:9200/lobid-organisations/_search?q=@graph.http://purl.org/dc/elements/1.1/subject.@value:*' yielding 15k hits. prefLabel don't exist.

fsteeg commented 10 years ago

@dr0i @acka47 Have a look at the new https://github.com/hbz/lobid-organisations repo. The resulting JSON-LD uses schema.org as its context, though the properties are not yet mapped to schma.org. Check out the result in the JSON-LD playground (see readme for details). I think it's the ideal place to evaluate using schema.org for organisation data.

acka47 commented 9 years ago

This is actually done and could be closed. Leaving open until https://github.com/hbz/lobid-organisations is finalized.

acka47 commented 9 years ago

Closing as the beta is running with schema.org data: http://beta.lobid.org/organisations
