Provide Occurrences-API

[nichtich]

As part of coli-conc we created an Occurrences-API to query occurrences and co-occurrences of identified subjects in K10plus. For simple occurrences the API serves one use case:

given a subject, how many resources about it does the catalog include and how can I deep link to the result set of this resources?

It's just one query parameter member with URI if the SKOS concept (e.g. https://d-nb.info/gnd/2015876-2).

In lobid API this would need to be translated to http://lobid.org/resources/search?q=subject.id:https\:\/\/d\-nb.info\/gnd\/2015876\-2%20OR%20subject.componentList.id:https\:\/\/d\-nb.info\/gnd\/2015876\-2&format=json&size=0 to get the totalItems and add boilerplate with information about lobid-resources and a deep link into the catalog:

{
  "database": {
    "uri": "http://lobid.org/resources/dataset#!",
    "prefLabel": { "de": "lobid-resources – Der hbz-Verbundkatalog als Linked Open Data" },
    "url": "http://lobid.org/resources/"
  },
  "memberSet": [  { "uri": "https://d-nb.info/gnd/2015876-2" } ]
  "count": 52,
  "url": "http://lobid.org/resources/search?q=subject.id:https\\:\\/\\/d\\-nb.info\\/gnd\\/2015876\\-2%20OR%20subject.componentList.id:https\\:\\/\\/d\\-nb.info\\/gnd\\/2015876\\-2"
}

Sure this is no rocket science, could be done in the client as well.

We won't be able to implement this in the coming months. Unassigning for now.

@nichtich is this still needed?

Yes, having this would simplify integration into Cocoda and the subject indexing application we are working on. Sure we can work without but then unlikely link to lobid.
