Currently I see no way in the GUI.
Possible other ways would be SQL, SOAP, in future REST.
If you want to strip off all up or down relationships of a document, then it could be done by a context sensitive velocity report that makes use of
RelationshipDao.getRelationshipsForDocument
with the flag you select up or downstream.
Then put that list into that call:
RelationshipDao.batchDeleteRelationships
But this would be dangerous, as everybody that executes that report world delete the relationships.
have not tried that, but I am pretty sure the following would work:
#set($rlshpDao = $applicationContext.getBean("relationshipDao"))
#foreach($vDoc in $documentList)
## delete up traces
#set($rlshp = $rlshpDao.getRelationshipsForDocument($vDoc.document.id,false))
#set($dummy = $rlshpDao.batchDeleteRelationships($rlshp))
## delete down traces
#set($rlshp = $rlshpDao.getRelationshipsForDocument($vDoc.document.id,true))
#set($dummy = $rlshpDao.batchDeleteRelationships($rlshp))
#end
could not resist, tested, works
