      When a user has discovered a data set they would like to use for their analysis, it could be that (part of) this data set is stored on cold storage, or that not all data products in the data set are not stored at the same location as the processing system they want to work on. This requires the science gateway to have functionality to initiate the replication of a data product to the storage that can be directly accessed from the processing system.

       

      The actual execution of the replication is out of scope of this feature and is the task of the Data Management System.

      AC1: The science gateway has functionality enabling a user to define a data collection
      AC2: This data collection can be submitted to the DM API to create a Rucio DID of that data collection
      AC3: The user can request replication of that data collection via the DM API
      AC4: The resulting functionality is documented and demonstrated to the ART
      AC5: The user can only invoke the DM Service in compliance with DM policies

    Description

      Tasks could include (sequence likely important):

      • Utilise Auth API client to request a token exchange for Site Capabilities API
      • Utilise Site Capabilities API to pull information about destination RSE (i.e. UUID)
      • Utilise Auth API client to request a token exchange for Data Management API 
      • Utilise DM API client to issue staging requests
