Make all resources symmetric
The following modifications have to be carried out:
1. Support for three different JSON formats: (1) proprietary EntryStore-specific JSON, (2) RDF/JSON, and (3) JSON-LD.
2. A unique MIME type for each of the JSON formats: (1) application/json, (2) application/rdf+json, and (3) application/ld+json.
3. Special cases do not have to be symmetric, e.g. includeAll exists only for GET and is very different from a plain GET.
