RDF support for orcid - FOAF profile

presents a simple FOAF profile for REST requests. Implemented by adding
org.orcid.api.common.writer.rdf.RDFMessageBodyWriter
and modified org.orcid.api.common.OrcidApiService<T>
to allow text/turtle and application/rdf-xml for viewBioDetailsRdf
by simply translating the XML JAXB bean into RDF. Thus existing
visibility checks etc. should work.

No write support from RDF is planned as it could get tricky if the RDF
contained additional statements that would have to be either thrown away
or stored somewhere per ORCID.

The implementations of OrcidApiService have been modified in both
orcid-pub-web and orcid-api-web -

TODO: Do we really need various methods like viewBioDetailsRdf and
viewBioDetailsJson, or just change them to have multiple @Produces ?

The remaining REST services have not yet been RDFized, doing this for
orcid-works requires some thoughts as to what existing vocabularies
and terms should be used - for instance BIBO ontology or simply
dcterms:bibliographicReferences etc.

RDF notes
=========

Vocabularies:

  * foaf:	http://xmlns.com/foaf/0.1/
  * pav:	http://purl.org/pav/
  * prov:	http://www.w3.org/ns/prov#

An ORCID (e.g. <http://orcid.org/0000-0001-9842-9718> ) is presented as a
[http://xmlns.com/foaf/spec/#term_Person](foaf:Person), with
foaf:givenName, foaf:familyName, foaf:mbox, etc.

The ORCID identifier represents the person (and not his record) and
can be used directly in Linked Data for attribution and provenance.

The ORCID record is identified as
<http://orcid.org/0000-0001-9842-9718/orcid-profile> - in the REST
interface both of these URIs return the same RDF (and XML), but the
distinction is that the second identifies the ORCID record at orcid.org.

Thus creation date of the record,
[purl.org/pav/html#http://purl.org/pav/createdOn](pav:createdOn), is when
the user registered on ORCID (the submission-date in XML), and if the
record was created on the website, then the person is also listed as the
pav:createdBy, foaf:maker and prov:wasAttributedTo.

If the ORCID has been claimed, then this will be a
foaf:PersonalProfileDocument - this is only the case if the user has
actually claimed (and presumably curated) the ORCID record, even if it
was imported through the API.
