[Rets-dev] Data definition -- queries or objects?

[Matt Lavallee]

Hi everyone,

As I peruse the RETS Commons DTD, I'm curious about some of the
conflicting uses of elements vs. attributes.

For an easy example, bathrooms.  Currently, the spec defines the
following relevant complex types (displayed as a tree for simplicity's
sake):

Property
	Baths
		BathsTotal
		BathsFull
		BathsHalf
		BathsThreeQuarter
		BathWainscotMaterials
	Bathroom
		isMainFloor
		bathroomSize

>From a clean inheritance model perspective, Bathroom should inherit the
attribute list of Room, and just add those attributes that are unique.
Redone, you'd see:

Property
	Baths
		Bathroom
			<inherit Room>
			BathSizeClass  (Full/Half/ThreeQuarter)

Also, the count of baths being summed under Baths.BathsTotal runs
contrary to the Rooms/Bedrooms syntax of Property.TotalRooms,
Property.TotalBedrooms.  Personally, I think it should be
Property.Baths.Total, or something to that effect that respects the data
structure while querying.

Anyone else with thoughts on this?

-Matt
