EnumeratedRepresentation
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
