Note: SPADE and PAIL DDI would be listed as part of the ADAPT representation system. 

  • Any DDI we do not understand should simply be passed through as-is
  • Use existing DDI's, or references to them, to represent well-known data representations
    • Use ReferenceId if there is a corresponding ISO DDI
    • Use CompoundIdentifier to track id, possibly domain specific id
    • Consider migration path to promote agreed-upon data representations to ISO
  • UOM's and business rules: Should we be able to assign a unit to a RepresentationNumber that is not supported by its Representation?
  • Do we always need a Representation, or are there times we only need a number and UOM?
    • Maybe only logged data meters need a representation
    • Added UnitNumber so we can have a number and UOM without a representation.
  • Will need helper method to get value in particular unit or unit system

ISO DDI has:

  • Numeric entity id
  • String "Definition"
  • List of Device Classes
    • Do we need a DeviceClass enumeration? (Planters, Fertilizer, Sprayers, Irrigation, etc)
  • Unit
  • Resolution (What is this? Some kind of scaling factor?)
  • Range
  • Submit by / date / company
  • Revision Number
  • Current Status (ISO-Published)
  • DateTime Status Date
  • Status Comments
  • Attachments
