h1. Collections as regular Arvados objects (Implemented August 2014 (See #3036) * Collections are assigned regular UUIDs * Collections have a regular @owner_uuid@ instead * Manifest hash goes into the @portable_data_hash@ field * @manifest_text@ and @portable_data_hash@ can be edited * Can access collections on API by uuid (returns regular record) or @portable_data_hash@ (returns record containing @uuid@, @portable_data_hash@ and @manifest_text@ with @uuid@==@portable_data_hash@) ** Setting/changing @manifest_text@ on its own updates @portable_data_hash@ ** Setting/changing @portable_data_hash@ on its own fetches the manifest from Keep ** @manifest_text@ and @portable_data_hash@ have to match * Add mutable @name@, @description@, @properties@ fields ** Use same logic for names/descriptions as already exist for other Arvados objects * 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 continues to be a manifest fragment or manifest hash+token stored in Keep ** Crunch-job continues to set job output to manifest hash+token ** Crunch-job creates output collection with @owner_uuid@ as the user (which means it will show up in the "home" project when #3499 is merged) * Pipeline runner is responsible for creating a collection in the target project and setting the name ** Add an @output_name@ field to the component description * When user clicks on a link to a collection uuid, it should include the expected portable data hash in the URL ** If there is a mismatch, it should throw up a warning and possibly tell the user what changed * Disallow content hashes in @head_uuid@ and @tail_uuid@ fields of links h2. Migration * Update schema to add @name@, @description@, @properties@ columns * Convert name links to collection objects owned by @tail_uuid@ and delete the name links * For remaining collections not accessible through name links, look for *can_read* permission links and create collections owned to the relevant user or group * Any other collections will remain owned by system user and will have to be assigned manually (?) * Update links (other than name or permission links) that point to a manifest hash to point to an appropriate collection uuid instead
