Re: Next steps

We seem to be talking about several different use cases, and there's a danger of commingling them. I suspect this is because each of us has a particular application in mind, but we're (presumably) trying to cover a somewhat broader area.

If I'm parsing this correctly, there are at least two broad scenarios:

(1) "AR": device detects a nearby POI (building, sign, ...) and performs some related action, visualization or other media rendering;

(2) "GIS" POI: An application wants to search for suitable POIs in a defined area, and then render them in some way. Active behavior or 3D wizardry is not necessary or called for, searchability, simplicity and uniform structure are.

I think there's a common intersection, but probably easiest by having pointers to properties and behavior that can then be ignored by other applications. For example, a POI "object" can easily include a set of URIs that contain related media, with appropriate tagging.

I was just thinking about the separation of these three parts. Maybe what I call representation is what other people call data? Note that both representation and data may need "layout" markup to explain how it should appear in our real world.
