I should have also mentioned... in Fedora 3.3 the relationships methods of the API have been enhanced to allow modification of datastream relationships, so you don't have to deal with manipulating RDF directly. These methods will modify the RDF in RELS-INT for you. For SOAP, see http://www.fedora-commons.org/confluence/display/FCR30/API-M#API-M-RelationshipManagement For REST see http://www.fedora-commons.org/confluence/display/FCR30/REST+API#RESTAPI-addRelationship and http://www.fedora-commons.org/confluence/display/FCR30/REST+API#RESTAPI-purgeRelationship -----Original Message----- From: Steve Bayliss [mailto:[email protected]] Sent: 12 January 2010 21:19 To: 'Vamsee Vanaparthy'; 'Fedora Users' Subject: Re: [Fedora-commons-users] Object Attribute Retrieval Hi Vamsee If you use Fedora 3.3 (recently released - http://www.fedora-commons.org/software/current) and enable the resource index, you can do this - see http://www.fedora-commons.org/confluence/display/FCR30/Resource+Index You can define "attributes" of a datastream (actually relationships, triples with the datastream as the subject) using RDF, in a RELS-INT datastream - see http://www.fedora-commons.org/confluence/display/FCR30/Digital+Object+Relationships You can then query those relationships using the RISearch service - see http://www.fedora-commons.org/confluence/display/FCR30/Resource+Index+Search and for doing this as an HTTP service (GET and POST), http://www.fedora-commons.org/confluence/display/FCR30/Resource+Index+Search#ResourceIndexSearch-ApplicationInterface Hope that helps Regards Steve -----Original Message----- From: Vamsee Vanaparthy [mailto:[email protected]] Sent: 12 January 2010 20:55 To: [email protected] Subject: [Fedora-commons-users] Object Attribute Retrieval Hello Guys, I have recently started my development of Fedora Commons and made good progress with it. I have few questions, I hope someone can help me with them. 1) I have defined custom schemas for different objects in my repository. Can we have custom attributes even for different data streams in the object. 2) If we could can you please let me know how we can retrieve additional information (meta data) for every data stream? I mean in the API-A wsdl we have listDataStreams method but it only retrieves Label, Mimetype and filename.
