XMI13 — Clearer support for data as well as metadata

  • Key: XMI13-9
  • Legacy Issue Number: 4635
  • Status: closed  
  • Source: gmail.com ( Barbara Price)
  • Summary:

    Despite the 'Metadata' in its name, XMI has often been proposed as a
    model-driven approach to XML for Data interchange: this is also reflected
    in the car-related examples in the submission and indeed in the RFP
    (section 6.1.1).
    Is this valid and if so should it be reflected in the evaluation or even
    the name of the standard?
    For example, in 4.5.6 it should also be explained how the (Meta)Model
    elements are to be used (if at all) when the XMI file is being used for
    instance data (e.g. actual cars as opposed to the model for cars). I
    presume that the MetaModel element would refer to the Cars model and the
    Model element would somehow describe this set of cars (e.g. "Cars in the
    company car pool as of 1/1/2001"). It might be better if these element
    names were not wedded to the 4-layer approach: more generally "Model" would
    be better worded "Content" and "MetaModel" would be better named "Model"
    (i.e. the metadata for the content).
    It would help if the M2, M1, and M0 examples were given for the same model.
