Hi Christian: That is a a problem in the documentation. Workflow ids are recognized (in the command-line tool) *only* in queue entries (i.e. when CLI is processing a queue). The general idea is that workflow Ids are transient, system-private identifiers, and should generally not be exposed. But in restricted circumstances (like deferred operation in queues), they are the only means of identifying an item.
But it's not true that tasks extending AbstractCurationTask can't work with workflow objects. For instance, any task that is wired into workflow calls 'perform(DSpaceObjects dso)', not 'perform(Context ctx, String id)' The 'perform(Context, id) signature is really (with the exception of 'all' for the whole site) meant for public IDs like handles. I'll try to correct the documentation: thanks for pointing it out, and sorry for the confusion, Richard On Mar 21, 2014, at 9:06 AM, Christian Scheible wrote: > Hi together, > > I'm currently working on a curration task and found a Problem in the > documentation/implementation of Curration Tasks.
