RE: Separation of Presentation from the Places/Things

The POI/Places draft edits should be out on the wiki for review.

Location is a primitive that consists of one for more types of descriptions of where a place is, such as X/Y, Address, MBR, vector of points, 3d constructs, etc.

A POI/Place consists of other primitives such as names, ID, what type of thing it is (category), a location, relationships to other POIs, meta-data about when it was created, who can use it, etc.

I agree that a prime goal should be the separation of the definition of a POI and a location.



A POI may need one or more locations to describe itself (navigation point x/y/z, display point center, main entrance door front, parking spots, a parcel area, a bounded polygon of linked X/y's, a set of navigable map references - link/side/spot, etc.).



POI's can and do move from one location to another (closed and moved across the street).



Locations may not always have POIs.



A location can be shared by several POIs (stores in a mall).

Subject: Separation of Presentation from the Places/Things



Hi,



a while back I posted a note about the Data Model coming in 2 main

flavours[1].



        1. the data describing the physical placement of the POI

           (e.g.lat/lon/alt/x-rot/y-rot/z-rot).

        2. the content the POI is linked to

           (e.g. title, description, type, keywords, favicon/thumbnail,

           3D model, etc.).



Looking back at it I think I didn't quite express it correctly...but the

idea is important and needs more discussion.  I think with point 1. I

was really thinking about Presentation.  With point 2. I was thinking

about the underlying Place or Thing that the POI was re-presenting.



On the Data Model page there seems to be a real blurring of these 2

types of data (e.g. "Apply some CSS-like "outer-glow: 3pt yellow;"

effect to your POI").



I think clarifying this abstraction would allow the two aspects of the

Data Model to develop more freely and independently.



NOTE: In the Mobile AR space there is a constant push for more freedom

in the Presentation layer (just like CSS enabled with the web).  But in

the Data Model discussion this is quite different from separation of

Markup and Presentation.



NOTE: Dynamic behaviour (e.g. scripting) may also need to be explicitly

separated out too.
