      Description

      In order to facilitate the independent development of both:

      1. ObsCore-compliant image metadata services (ObsTAP and SIAv2); and
      2. a SODA service

      we need a near-term-usable definition of how to construct ObsCore obs_publisher_did values for data in a Gen3 repository.

      "Near-term" is meant to mean at a minimum "expected to work for Gen3-based HSC datasets" and usable for them for the DP0 data release and the Spring 2020 LSP testing round.

      It would probably be good to have an idea for how this would also work for LSST simulated images (e.g., from DESC DC2), should these end up being part of DP0 but this is not a requirement for this ticket.

      Nor is it a requirement for this ticket that either

      1. we devise a solution that is relevant to the LSST operations era or
      2. the proposed solution continue to work without change throughout the rest of construction and commissioning.

      It is OK if a redesign turns out to be needed somewhere along the way. It is more important that we get this off the ground.

      The deliverable from this ticket is a written spec, not code.
