• The implementation of visibility (i.e., PUBLIC, PRIVATE, SHARED) has not yet been fully designed.

Get List of Items in a Virtual Collection with Pagination

...

Sorted by List Order

Data Referenced in Query

• VirtualCollectionRDF.owner == _CURRENT_USER_URI_
• VirtualCollectionRDF.rdf_subject == _SELECTED_VIRTUAL_COLLECTION_URI_
• VirtualCollectionItemRDF.proxyFor == _SELECTED_VIRTUAL_COLLECTION_URI_
• VirtualCollectionItemRDF.next - assume it plays a role in the query since this predicate specifies the list order
• number of items to return in the results
• token identifying starting point for next set of results

Data Returned

• VirtualCollectionItemRDF.rdf_subject
• VirtualCollectionItemRDF.proxyFor
• VirtualCollectionItemRDF.visibility
• BibliographicReferenceRDF.rdf_subject
• BibliographicReferenceRDF.title
• BibliographicReferenceRDF.description
• BibliographicReferenceRDF.author
• BibliographicReferenceRDF.pubdate

Example Query

Example is INCOMPLETE -- Does not address sorting and pagination issues

# _CURRENT_USER_URI_ = "http://localhost:3000/individual/p234"
# _SELECTED_VIRTUAL_COLLECTION_URI_ = "http://localhost:3000/individual/vc123"
SELECT ?vci_subject ?title ?description ?author ?pubdate
WHERE
{
   ?vci_subject <http://www.openarchives.org/ore/terms/proxyIn>  <http://localhost:3000/individual/vc123>
   <http://localhost:3000/individual/vc123> <http://purl.org/dc/terms/creator> <http://localhost:3000/individual/p234> .
   ?vci_subject <http://www.openarchives.org/ore/terms/proxyFor> ?biburi
   <http://localhost:3000/individual/vc123> <http://www.openarchives.org/ore/terms/aggregates> ?biburi 
   ?vci_subject <http://TBD/visibility>                          ?visibility .
   ?biburi      <http://purl.org/dc/elements/1.1/title>          ?title .
   ?biburi      <http://purl.org/dc/elements/1.1/description>    ?description .
   ?biburi      <http://purl.org/dc/elements/1.1/creator>        ?author .
   ?biburi      <http://purl.org/dc/elements/1.1/date>           ?pubdate .
}

Notes

• The concept of owner will not be represented by dc:creator.  See Triples Examples page for more details.
• The inclusion of the <virtual collection> <owner> <person> triple is a sanity check that the current user has permissions to view this item.
• The inclusion of the <virtual collection> <aggregates> <biburi> triple is a sanity check that this item is actually in the selected virtual collection.
• The implementation of visibility (i.e., PUBLIC, PRIVATE, SHARED) has not yet been fully designed.
