  • Federation config

...

    • Esme and Eric set up a sample configuration for filesystem federation

 

    • Esme:
  • Only thing that works is so far setting up filesystem federation once
    • Initial set up of filesystem federation works as expected - changing the config and reloading breaks things.
    • Looking for ways to change and reload config, added debug statements to trace issue
    • Adam: We should talk to Modeshape; should be their issue

...

    • Esme: will open a ticket on Modeshape
  • Eric's federation issue: applying auth rules on federated nodes

       

        • When setting ACL in federated content, an error is thrown.
        • ACLs are persisted as children nodes of resources and resource names are namespaced. This is problematic with the current filesystem connector.

       

        • Andrew: if we are not able to resolve this in current sprint, we should lay out in the wiki what the issue is and possible approaches to tackle the issue in subsequent sprints.
      • AIC async derivative generation

           

            • Currently CMS generates derivatives.
            • With Fedora 4, derivatives will be created by sequencers, thus asynchronously
            • How do we monitor derivatives being generated?
              • Async API: it's planned further down the road, so it's not an option for now
              • External messaging system: better solution, client should rely on messages sent directly from sequencers.
            • How do we know which derivatives are expected once master file is ingested?
              • We don't want to hard-code list of expected derivatives in client for each resource type
              • We can use SPARQL query to find derivatives

          ...

              • Andrew: a suggestion would be pre-populating derivative datastreams with placeholder images

           

          ...

            • Planning for Hydra updates to work with F4

           

            • Andrew: will discuss list of features planned for 4.0 - consistency in messaging is important

          ...
