Re: Recording geolocation of the annotation (where the annotation has been created)

Hi Bob,

Yeah, that makes sense as a use case, but is it really annotation specific?
In the sense that I can think of plenty applications that would need that, and yet have nothing to do with annotation. Does it make sense that these applications would have to use the OA ontology to match their requirements?

It's a bit as if OA had re-invented a big part of the PROV ontology to match very generic requirements...

Summing up my position:
Explaining in OA documents how to use other standards: yes.
Introducing in OA new geolocation properties: no.

Cheers,

Antoine



> I agree that an important question is what are the use cases. For example, if the use is to find out how far from location L the annotation was created, one must perhaps know the accuracy of L and of the creation location.  Other provenance use cases may require 2d representation.  For example if you annotate a feature of a picture of the Eiffel tower
> and give a point   creation location near the  tower, i might respond that you cannot see that feature from that location.

Are they so common, and specific, that you would have to handle them by introducing a new property in OA? I'd be tempted to just rely on any general solution for recording any user-generated events...

Is it the annotating or serializing activity, in PROV terms, which the location is referring to?
