Registry Workshop 2025‐05‐27

Agenda

• Robustness issues and solutions:
  • "noisy neighbor" issue
  • solutions so far:
    • increase maximum resources available
    • increase retry/wait time intervals for harvest: to be released.
• Cognito users internal maintenance
• Alternate data file path management
• Q&A

Minutes

Robustness

Pat/Anne comments/questions:

• nodes might run multiple harvests at the same time.
• moving to the cloud will require re-harvesting, and more resources needed.

Anwers:

• EN is adding solutions as problems occurs, without over-engineering
• EN is aware that the registry is being used more, as it should and is prepared to react quickly to new resources challenges.
• EN might need to implement a fair API to allocate computing resource for indexing equally for all nodes.

Cognito user authentication upgrde

Nodes have been informed of the update done last Friday.

Alternate data file paths

• Here is the parent theme for this task: https://github.com/NASA-PDS/registry/issues/266

• Need use cases, examples user-side for alternate format/path.

• The links between alternate paths and path defined in the labels need to be available in the registry.

• Possibly useful standard vocabulary for access types: https://vocabularies.coar-repositories.org/access_rights/ Controlled Vocabularies for Repositories: Access Rights
