Models

  • [MCD] The models used in these serializations do not map to any existing model/model-in-progress with the possible exception of Dataset.
    This makes it difficult to compare annotations since the basis is not the same.

Annotation

  • [MCD] Annotation syntax allows for duplicating content, or referencing PARAM|FIELD if ID is available
    • so, I think this syntax has minimal impact on the native content.
    • FIELDs, I suppose, MUST have an ID. This is true with all of the annotation schemes?
  • [MCD] Relies on clients to use VOTable content to fully resolve model elements.
    • use FIELD ucd="phot.flux" or "phot.mag" to identify/destinguish the nature of the axis as Magnitude vs Flux
      The UCD value is the ONLY difference. Well, the PhotCal instance includes a reference to the respective columns, but that is not part of the PhotDM model.
