[tdwg-tapir] OGC standards and TAPIR

Before we jump in bed with GML (which I have been in favour of in the 
past) it is worth looking at the other side.

This is an interesting article/opinion on GML:


And somewhere down this page is a blog by a guy talking to Ron Lake 
about getting RDF stuff in GML or visa versa which makes good reading.


If we think about integration of technologies then it seems to me that 
we want to be able to plug into as many other domains as possible. If 
some one wants to pass information around about people or buildings or 
DNA  along side herbarium specimen data then we should not make up a 
schema for it the user should be able to use any of a whole bunch of 
widely acceptable, cross domain ontologies/vocabularies. They should 
pick the one most suitable to them.

If we go with pure GML then we may end up having to invent or port 
things to it that aren't of interest to the geographic community. GML 
may be a bunch of cartographers trying to invent their own semantic web. 
GML applications may be nearly as far away from plugging in to 
"everything else" as we are.

So maybe a one night stand or an open marriage but not total commitment 
unless we can see a path to more generic W3C standards - is what I'm 
thinking at the moment.

All the best,
