2019-07-11 DSpace 7 Working Group Meeting


 from 14:00-15:00 UTC

Location: https://duraspace.zoom.us/my/dspace (Meeting ID: 502 527 3040).


  • (15 mins) Developer Stand Up - Developers give brief updates on their effort (or their team's effort).

    • Update/see "Current Work" section below based on your status. Please feel free to update prior to meeting.
    • Please highlight any new work (needing reviews/testing), any blockers (for you), and any discussion topics you may have.
  • (30 mins) General Discussion Topics
    1. (Topic #1) Short mention from Andrea Bollini (4Science)about the strategy to adopt to manage relations (entities) in the submission. The expectation is to enhance/update the workspaceitem endpoint as required but to don't use directly the item endpoint (i.e. /api/core/items/:uuid/relations). As soon a design document/PR/idea is ready Andrea Bollini (4Science)will be happy to provide feedback, please just ping
    2. (Topic #2) (Used time for a deeper discussion of outstanding PR)
    3. Improved Estimation Strategy for Beta release. (Estimates should include time for discussion / code reviews, also should be done by multiple developers)
      1. Development Planning Spreadsheet needs to be updated, so that we can determine what (outstanding) tasks need estimation.
      2. Will be using Wideband Delphi estimation technique
  • (15 mins) Planning for next week

  1. (Blocked PRs go here)

Delayed / Needs Discussion

  1. Initial Performance Testing from Chris. Needs detailed discussion in a future meeting
  2. (REST Contract) Edit Homepage News: https://github.com/DSpace/Rest7Contract/pull/45
    1. Delayed until after Preview release. 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.
  3. (REST) Scripts & Processes endpoint: https://github.com/DSpace/Rest7Contract/pull/17
  4. 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.
  5. Not discussed much, but could there be opportunities to use Travis CI + Docker Compose for testing of Angular??


  • Most of meeting involved a detailed walkthrough/assignment of outstanding PRs (in order to move them forward ASAP).  Notes are inline above.
