10:00 am ET

Attendees:

Terrell Russell, Kory Draughn, Alan King, Jessica Natonick, Lazlo Westerhof (Utrecht)

Minutes

Update/Discussion:

  • Utrecht has already done this separation
    • UI Schema - React valid JSON-Schema form information
    • Metadata Schema - valid JSON-Schema
    • Research space - no metadata required, but can fill it in
      • Same schemas, just ignore the 'required' errors
      • Implemented in python, using the validators
    • Vault space - has to be requirements, export/publication mandates
      • Enforces the full schemas
  • Microservices (as plugins, not irods/irods at the beginning)
    • UU has a python ruleset
      • When metadata file is updated, rules fire to push/pull into the iRODS AVUs and back to JSON file
      • Schemas live in iRODS themselves, but are referenced by collection_name (which holds both schema files - by contract/assumption)
    • Do these AVUs need to be protected by metadata_guard?
      • A: irods::metadata_templates
      • V: http://coolthinghere
      • U: data [data/ui]
      • These are on a collection? And/Or a data_object directly? Not at UU.
      • UU has no recursive references yet, still flat
      • Jonathan Melius also probably interested
    • Attach (type, schema, object_id)
      • Initially, type will just be 'url'
      • Could later be 'irods_schema' and store the id from the new table
      • Or 'form' for ManGO wrapper/form information
    • Detach (type, schema, object_id)
    • Validate (object_id, recursive)
      • Run gather (below) to build the effective json schema
      • Get and build json payload with all current AVUs
      • Run payload and schema through validator
      • Return result (OK or failure/explanation)
    • Export/Collapse/Rasterize/Gather/Dump (object_id, recursive)
      • Find all associated schemas and construct 'effective' schema
      • Recursive would check/gather all parents up to root
  • Next Meeting
    • Sept 2023
