Hi Vincent
There are two methods to update relationships using API-M
The easiest is probably to use the relationships methods - see:
https://wiki.duraspace.org/display/FCR30/API-M#API-M-RelationshipManagement
and the corresponding methods in the REST API at
https://wiki.duraspace.org/display/FCR30/REST+API#RESTAPI-APIMMethods
The second is as you suggest - read the RDF directly (eg API-A
getDatastreamDissemination) , modify it in your application, and then update
RELS-EXT with the updated version (eg the API-M modifyDatastream methods).
Full documentation on the REST and SOAP APIs is at:
SOAP: https://wiki.duraspace.org/display/FCR30/API-A and
https://wiki.duraspace.org/display/FCR30/API-M
REST: https://wiki.duraspace.org/display/FCR30/REST+API
Regards
Steve

Subject: [fcrepo-user] Modify RDF content
Hi,
Currently I add a custom node (isFeatured) in the RELS-EXT Datastream to
grab objects I want to feature in my repository. I didn't really know any
other way to do this so I used the RELS-EXT Datastream. I want to modify
RDF Datastream to add this custom node using Fedora APIM. Is there a way to
do this? Or is there a way to read the RDF Datastream as an XML and add a
node and then "re-add" the datastream? Please let me know if there's a
better way to achieve this functionality.
Pardon any ignorant questions I may ask, as I'm still a Newbie.
Vincent Vu Nguyen
