Best Way to Extend the Geo Vocabulary to include an "error" or "extent" radius in meters

Hi LOD'ers,

There was some discussion about ways to record species observations using
the geo vocabulary at a recent biodiversity informatics meeting.

Some see the advantages of using the geo standard, but we really need to
have a way to incorporate and error or extent in meters.

What would be the best way to extend the current geo vocabulary so that it
includes this radius measure but still works well with geo aware tools and

The addition would be defined as the total extent including calculated

This would be used to record that a species or "thing" was observed or
collected within this geographical defined area.

Something like the example below, but I suspect that this might not make it
a real geo:Point?


This should work so that if I have 10,000 records recorded from within this
same area,. I can define it once and then refer to that area description RDF
in the 10,000 species occurrence records with one simple URI to that area

One solution would be for the geo authors to add the radius to the geo

Also there may be unrelated groups that might like the radius attribute for
some other use.

Another alternative would be to somehow extend the geo vocabulary within a
separate vocabulary.

It is not clear to me what is the best way to do this and still retain geo

I look forward to ideas and suggestions,

- Pete
