Collections as regular Arvados objects¶

• Collections are assigned regular UUIDs
• Collections have a regular owner_uuid instead of the system user
• Manifest hash goes into the portable_data_hash field
• Add mutable name, description, properties fields
• Continue to use manifest text hash (portable_data_hash) for crunch
  • Choosers set the value to the manifest hash, record the selected collection uuid on link_uuid
  • Task output is manifest fragment or manifest hash+reader token stored in Keep
  • Crunch-job continues to set job output to manifest hash
  • Add optional output_name and output_owner fields to job submission
  • When job completes, collection is created under output_owner, given output_name, and the collection uuid is recorded under new output_uuid field
    (Side note: job should not be marked as successful/completed until all its output and logs have been uploaded.)

Migration¶

• Create collection objects from name links
