      1. Review scope, use cases and solution architecture.
      2. Timeboxed activity to evolve or pivot current solution for serving data (working with MCCS on the server & client APIs).
      3. Collect data files to be served in one place (work with MCCS).
      4. Write clear documentation for how to add and access new data items through the library from the perspective of SKA developers (specifically cross-ART)
      5. BDD style test(s), exposed to Xray, for this service one from SDP and one from MCCS usage sides), eg.
        • Given an SDP visibility receive workflow is running
        • When the workflow requests a specified version of station/dish coordinates from the Telescope Model service
        • Then these are available to the workflow for subsequent processing

    Description

      Who? 

      For developers of systems needing a single source of truth for telescope model/instrument configuration data.
      Keep scope limited to start with to SDP and MCCS use cases - will evolve or pivot in future if successful 

      What?

      A solution that provides a single source of truth for telescope model/instrument configuration data, limited in scope to a few (TBD, see list below) data models needed for SDP and MCCS for AA0.5.

      Needs to consider use cases and data models with a limited scope starting with SDP and MCCS possibly including:

      • Static and limited dynamic data 
      • Data versioning (with timestamps on versions?)
      • Data models (and formats)
        • Station coordinates
        • Aperture array coordinates
        • Aperture array connection map/list (probably not the right term - check with
          m.waterson
          )
        • Haslam map (list of HEALPix pixels)
        • RFI Masks
        • (Embedded element beam pattern coefficients?)
      • ...?  (needs to be worked out in PI14 but not expected to be a complete list - just need to find out what we need in the short term based on needs of SDP and MCCS in the first instance)

      Review and evolution of current solution https://gitlab.com/ska-telescope/sdp/ska-sdp-tmlite-repository with consideration for data backend, service interface, and client library (can probably just persist current solution )

      A client library that provides a solution to make it easier for application developers to exercise this interface

      Simple data backend which supports the data models and data versioning 

      Simple service interface that abstracts how data is stored and hides it from the client

      Why?

      Single source of truth for configuration data that needs to be shared across the telescope, if we don't have this we'll have a massive headache trying to make sure data such as antenna coordinates are shared between sub-systems.

      Needs to be able to support versioning so we can reason about what configuration was used for any given observation/test.
