Minutes

Update/Discussion:

  • Subject areas should drive this work
  • Server can only react to specific requests
  • Consider recasting this group to be 'Metadata' rather than about Templates
  • iRODS can't/shouldn't be defining the templates for anyone?
    • Site-specific knowledge and interfaces are too diverse
  • PEPs / microservices / functions to validate, but not manage the templates themselves
  • Template management is too big a task for the server/policy
  • Metadata for search is very different than metadata for validation/orchestration/policy
  • Optimizations for retrieving metadata for orchestration and/or policy
  • Investigate unused description column in the AVU table
    • Instructions for the human creation
    • Possible type system on AVU
    • Behavioural types for AVUS
    • Permissions, to allow non-owners to annotate / use AVUs
  • Consider breaking apart the functionality of what a template does
    • Annotation
    • Validation
    • External references
    • Define parent/child relationships between metadata elements
      • Recursive query syntax of SQL
  • These parts together could be stitched together on a per site/application
    • Provide 70-80% of the original intent of metadata templates
  • Goal: iRODS metadata to become a first class citizen
    • Indexing and templates and policy are downstream from the 'truth'
  • Next meeting:
    • Work on a whitepaper / lessons learned / goals
    • August 2021
