    ParameterSpecValue would benefit from being split into its two constituent parts: the set of attributes that apply for integer ranges (valueFrom, valueTo, rangeStep), and the set of attributes that apply for discrete values (value). It might also be good to clarify whether discrete values are meant to be interpreted as plain strings, or as string representations of integers (meaning that it must be possible to convert the string to a valid integer).

    HI, 

    Are new classes going to be defined as abstract classes ? 

    Current ParameterSpecValue class is mixing up multiple alternatives. We should consider to clarify them and consider Jacqueline´s split proposal ?  


    1. Kevin Scaggs

      Hi Michela,

      These are concrete classes as specified.   They can be instantiated.

  4. Chuyi Guo

    Yes, I think they are abstract classes.

    It seems Jacqueline´s proposal is going to detail the expression of ParameterValue, but the original thoughts is that the  ParameterValue comes from the design time given values, so maybe don't need to specify again in run time side? I'd like to wait for Kevin's comments.

    1. Kevin Scaggs

      ParameterGroup is a set of concrete classes - they can be instantiated.   Some are instantiated as "design time" while others (the ParamaterValue) is instantiated at runtime.

  5. Michela Bevilacqua

    HI,

    abstract classes should be identified in italic, please review it.

    I think we need to discuss about ParameterSpecValues definition.

    1. Kevin Scaggs

      Hi Michela,

      Given you were not at today's Resource IM call, could you post your concern here?

  6. Michela Bevilacqua

    HI Kevin, apologize for today.

    I continue to think that parameterSpecValue class definition should be improved as it is mixing up different options together without providing a clear view of what are the valid options. 

    For instance , what is value ? a default or a an alternative to value from jointly used with value to ? 

    Anyhow, to progress, can we move the model to clean but take an action to review ParameterSpecValue as a modelling task in the next weeks ?
