Blocked

Delayed / Needs Discussion

1. Managing Authorization info in Angular UI: How to pass Authorization rights (i.e. logged in user's access rights) from REST API to Angular?  See for example: https://github.com/DSpace/dspace-angular/issues/393
   1. In July 25 meeting, we noted this probably cannot be resolved with just one simple solution. May need to look at different options for different scenarios
   2. Work is ongoing, but has been started in these areas:
      1. Summary of ideas: REST Authorization 
      2. Contract for Authorization Endpoints: https://github.com/DSpace/Rest7Contract/pull/92
      3. Contract for ResourcePolicies: https://github.com/DSpace/Rest7Contract/pull/87
2. REST API Projections:  Unable to locate Jira server for this macro. It may be due to Application Link configuration.
   1. Work begun in https://github.com/DSpace/DSpace/pull/2547 (by Chris Wilper)
      1. Based on detail discussions in our Oct 17 meeting. 
   2. (Outdated) Early work begun at https://github.com/DSpace/DSpace/pull/1847.  Discussed in more detail in our Aug 22 meeting.  Overall, this approach seems like a good direction, need volunteers to move it forward.
   3. https://github.com/DSpace/Rest7Contract/issues/2 (discussion resumed by Andrea Bollini (4Science) could be relevant for the projection)
3. Initial Performance Testing from Chris.
   1. https://cwilper.github.io/dspace-perftest/
4. (REST Contract) Edit Homepage News: https://github.com/DSpace/Rest7Contract/pull/45
   
   1. Delayed. General agreement (in meeting on March 21, 2019) that storing HTML in metadata fields is not really ideal behavior.  Metadata (from a librarian standpoint) tends to be free of format-related markup (as that allows for easier sharing, understanding of metadata.  Currently Community & Collection homepage information is HTML-based and is stored in metadata that is appropriate for a minor subset of information (like the title) but it is better to move large/rich text to bitstreams.  
   2. Proposal here is to consider storing HTML-based markup (for Site, Community & Collection homepages) in Bitstream(s) associated with the object in question.  May allow for more CMS-lite behavior in the future
   3. Timeline for this is uncertain.  Possibly in 7 or 8. May depend on how/whether it can be scoped.
5.  (Angular Bug) https://github.com/DSpace/dspace-angular/issues/368 ( Art Lowel (Atmire) )
6. Concurrency in DSpace 7 (or 8).  What do we want to do when multiple editors are editing the same object?  Needs further analysis regarding implementation details
   1. We've decided (in meeting on March 7, 2019) to use ETags to implement concurrency. REST Contract notes on ETags: https://github.com/DSpace/Rest7Contract#etags--conditional-headers
   2. ETags only update of the two fields match. If someone edits first, your edit would fail and you would get a fail response (422?)
   3. ETags seems to have broader support in other REST APIs.  Recommended also by both Art and Andrea.
