Minutes

Retiring m2.duraspace.org

  • Hosts a number of Maven artifacts that Fedora 3 needs
  • We would like to retire it
  • One approach: retire very soon and offer a script and JAR files to build the latest version of Fedora 3
  • Another option: Continue maintaining the server (not very appealing)
    • Someone else could stand up the server on their own infrastructure and redirect the DNS
  • We could send a post to the mailing list asking if anyone wants to maintain the server
  • There are probably very few people interested in building Fedora 3 vs. just using the installer
    • For these people, will Andrew’s build script work as an option? 

Server-managed PREMIS predicates 

  • There are some server-managed predicates in Fedora 4 now
  • In some cases users want to manage their own PREMIS properties but they are currently immutable
  • Should we stop using non-Fedora predicates for server-managed properties?
  • We have to reserve some LDP properties, though many can be updated via SPARQL-Update
  • In the case of PREMIS/fixity, should we (1) use a Fedora namespace, or (2) continue to use PREMIS but allow the properties to be mutable?
  • Recommendation: Investigate allowing fixity-related properties to be user-modified
    • Longer-term: Investigate using a server-managed Fedora namespace instead of PREMIS

ModeShape performance issue with many child nodes

  • This issue has been addressed by the ModeShape community by creating a new node type
    • The only issue is that this new node type won’t work with versioning
      • Might be possible to have the root node be of this type and all other nodes be of the normal (versionable) type
      • This mix of versionable and non-versionable containers might be cumbersome
    • Need to add some concerns as comments on the PR
    • We need to run new scalability tests with these updates
  • No labels
