I took the locations primitive which Karl provided

http://lists.w3.org/Archives/Public/public-poiwg/2011Jan/0017.html

as well as the suggestions from Roy Davies

http://lists.w3.org/Archives/Public/public-poiwg/2011Jan/0007.html

and created, based on those, a laundry list of what could be included in 
the "objects primitive".

As Roy suggests and we discussed on the call January 26, an Object has a 
location but it can change over time (in which case it is a NON-FIXED 
POI), or not moving (in which case it is a FIXED POI).

I welcome feedback.

Regards,

Christine

Object Primitive

Goal:
Provide a rich and flexible description of an object (aka a thing)
De-couple or isolate the description of an object and from where it is 
(a Place of Interest) and other primitives.
An object has one location at a (temporary-duration undefined) specific 
point in TIME but does not have one fixed point over time.

An Object of Interest can be a parent to other Objects each with its own 
description to allow for the representation of complex objects that are 
the aggregate of a collection of Objects (a car, boat, or airplane).
It should not be inferred that each of the elements within the object 
primitive are not spatially synonymous, but do refer to the same object.

High Level Attribution:

Object Name
Object's Absolute Location at last known time
Identification

Object's category [living, non-living]

Object's Attribution Details

Identification
                 ID (optional)
Identification System or Service
ID
Associated IDs

Name
Last Updated On : Date/Time  (optional)
Updated By : owner / author (optional)
Use : public, private, restrictions (optional)
Ownership info : owner of all or part of a POI
Cost - each point can cost more for the people who lease it from the 
layer owner.

Status : Active, blocked, deleted (optional)
Trustworthiness : degree of certainty the author has in the accuracy of 
the object

Category

Object (optional)
                                 Type
Living - composed of one or more cells
Non-living - inanimate, not composed of cells

[Then we can classify according to animal or plants, mammal, etc!]


MORE OPTIONAL INFO ABOUT OBJECTS:
Circumference/radius (the description applies to this Object plus the 
space around it?)
Is it planar or 3D?
If it is planar, what are its X&Y dimensions? This is the equivalent of 
area for the location primitive.

If it is 3D, what is known about it?
Volume
Density

Identification (optional)
Supplier: who made this object?
Version: what is its version?
Associated Object ID
Trustworthiness of this information?


What are its relationships to other objects?
Is it near a fixed object? How near?
Does it belong to someone? A company or an individual?
Connected- Part of a larger entity (a motor?)
Independent- not part of a larger entity
