Subject: Updated Location Primitive

All,

Below is a 2nd draft of the location primitive based on your feedback and review of the initial draft. Will post on the POIWG Wiki.

Locations Primitive
Goal:
Provide a rich and flexible description of a location
De-couple or isolate the description of a Place of Interest from its geospatial location, since many Places can be at the same location, and Places of Interest can change locations.
A Place of Interest can be a parent to other Places Of Interest each with its own location to allow for the representation of complex places that are the aggregate of a collection of Places (campuses, business with multiple entrances, large constructs like parks, etc.).
It should not be inferred that each of the elements within the location primitive are not spatially synonymous, but do refer to the same place.
Restrictions:
A Place Of Interest must have a location
A Place of Interest must have one location.
High Level Attribution:
Place Of Interest
...other descriptive primitives
Location : required
Identification : required
Geo-Reference : required

Supported by : Change-Reference primitive : optional
<to be defined later, for reuse across other primitives and attributes to describe ownership and change data>
<for example below>
Last Updated On : Date/Time  (optional)
Updated By : owner / author (optional)
For Use By : public, private, restrictions (optional)
Current Status : Active, blocked, deleted (optional)
Trustworthiness : degree of certainty the author has in the accuracy of the information in the associated primitive, based on a 5 star (high) to 1 star (low) simple rating

ID :  required : +Change-Reference : number or string
Name : optional : +Change-Reference : reference or name
Path to ID : optional : +Change-Reference : URL path to the Identification System or Service : Change-Reference
Associations : optional : +Change-Reference : list of other replacement, old or depreciated IDs that belong to this ID  : Change-Reference
Geo-Reference : required

Type : required : one of : Start/End/way point
Coordinates : required : <see above for details>
Area : optional : +Change-Reference : for representing a line-bounded area
Point : required : repeating for a directed linked list of points
Type : required : one of : Start/End/way point
Coordinates : required : <see above for details>
Object : optional : +Change-Reference : for representing a 3D object, building, etc.
TBD
Undetermined : optional : +Change-Reference : for representing a location as yet undetermined, such that a Place and its description can exist prior to the final location being resolved

Subject: Pachube and POI

Hello,

During our meeting January 26 I agreed to do some research on Pachube as a basis for understanding the needs/possible synergies between this platform and the POI WG work.

The specific area we would like to better understand is how to manage the frequent requests for information, and frequent updates to information in a database. I thought that the requirements we have for objects which are changing locations over time might have something in common with what Pachube does.

I want to introduce those of you who are not familiar with it to the system.

>From the home page:

Pachube is a data brokerage platform for the internet of things, managing millions of datapoints per day from thousands of individuals, organisations & companies around the world. Pachube's powerful and scalable infrastructure enables you to build 'Internet of Things' products and services, and store, share & discover realtime sensor, energy and environment data from objects, devices & buildings around the world.

I suggest that you study:

http://community.pachube.com/quickstart_no_code

http://api.pachube.com/

http://community.pachube.com/software_hardware

What are your thoughts?

Regards,

--

Christine
