goal of the work in this branch: update the RDF schema used in Sesame repository to be in line with proposal from Working Group PS1
Merge branch 'master' into feature-rdf_schema_update
'org' and 'locn' ontologies used partially in line with PS1 proposal (for now we do not have an address registry so address is linked via blank node)
vocabulary clean-ups and fixes
enhancements to vocabularies + linking of org. data to donation data via Company URI
further clean-up: 'xSupplier*' -> 'supplier*'
further clean-up: 'xGift*" -> 'gift*'
bumped up release version
further clean-up of schema
better data linking + some RDF serialization fixes (in regards to the source URL)
clean-up: small refactoring of serialization so that is is little simpler
ICO now serialized as 'adms:Identifier' (and 'rov:RegisteredOrganization' links to it)
clean-up: further refactoring of serialization to make it simpler: getConceptRdfAbout() removed
RDF output optimization/clean-up: do not put NS definitions where they are not used
serialize float number always in same way, irrespective of current
locale
clean-up: removed file which are generated by Eclipse/Maven and do not need to be versioned
clean-up: files which are generated by Eclipse/Maven and do not need to be versioned put into .gitignore
RDF data: 'opendata:supplierIco' and 'opendata:donorIco' predicates were
removed as "newer, better linked, more shiny" 'opendata:supplier' and
'opendata:donorCompany' prodicates replaced them
