Surely this would be covered be just letting any data be linked to a
non-fixed location?

I certainly see value in tyeing POI information to non-fixed
co-ordinates, even given by image recognition, markers, RFID or some
other technology. But I'm not sure I see value it tieing it to a
"concept" such as a person - because theres no way to locate a person
without using some other technology.

Generally speaking, AR is about linking digital information to the
real world. You can link something to a person already ver, say, an
address book. But without a way to get this into the real world, its
not really relevant to AR.

So I'd say "+1" to tyeing any data to generic moving objects....which
could include people.
So that would be [method of identification - image/RFID/marker] tied
to [data/url etc], where the data or url could describe a person, or
be a link to a profile online or an existing standard format.

But I don't think theres any benefit to having a separate definition
for a person directly in the POI spec, as a lot could be said about a
person and I think it would be making the POI spec too large to deal
with it on its own. At the same time specifying a person doesn't help
a device know when/where to display the information.

Better to focus on the "link" between the real and the virtual, and
let the actual data being linked to be anything.
