Review current status


  • Need to restate queries in plain language

  • Query for events at repository level and resource level


  • REST API would not be used to POST internal events - only external

  • Use case: bulk operations. Give me all the resources that were ingested on a given day

    • To what extent should the repository support queries as opposed to exporting to a triplestore for the queries?
      • Should probably limit querying within Fedora and focus on exports
  • Scheduling exports

    • Could be done with an external tool

Events and event agents

  •  External events

    • Use case: pull in audit history form F3

    • Creation vs. migration: the date an object was created in a previous repository vs. the date it was imported into F4

      • The repository will record a system date for when the resource is created/migrated, but a semantically meaningful created date could also be supplied


  • The recommendation is to use PROV-O in combination with PREMIS
    • There are too many PREMIS classes. These can be used as sub-classes of 3 PROV-O classes
    • Internal data model should be informed by PREMIS so we can map to that level of granularity without trouble

Next steps

  • Review events and agents

    • Make sure they cover your needs
    • Suggest edits as necessary

    • Need to push this investigation deeper
    • Find out who else is implementing these ontologies
  • Queries

    • Need to translate queries into plain language
    • Add any final comments to unanswered questions
    • Offline discussion on the mailing list re: what we will support from the repository perspective
  • Schedule another call before implementation starts (March 30)
  • No labels
