[wip] cardsearch api

[aaxelb]

a search api

accepted oddities:

• jsonapi/ld serialization:
  • every value in resourceMetadata is an object with either @value or @id (so there's no mistaking text for an iri, and there's always a place for @lang if we have it)
  • there is no @type, only resourceType
  • propertyPath has an explicitly ordered list using @list

known TODOs:

• api features
  • [ ] jsonapi include param
  • [ ] jsonapi sort param
  • [ ] search-result pagination
  • [ ] index-property-search
  • [ ] index-value-search
  • [ ] test coverage
  • [ ] error responses with codes and messages
• osfmap representation:
  • [ ] dcterms:subject expressed different ways in different places (ideally would use an iri but that'll take osf-side change)
  • [ ] reconcile registration_form, dateWithdrawn, and withdrawalJustification with OSFMAP
  • [ ] reconcile sharev2 Award with osfmap:FundingReference
