Hi Gobe,
I can see that you have documented the OGC process, and HOW external 
people can engage with this process.
However, I'm really looking for a Vision and Technical Roadmap which 
OSGeo can follow (re Terminology definitions). I feel you haven't 
addressed our OSGeo use case. And in particular, I'm not seeing an 
integration strategy between OGC and OSGeo.

On behalf of the OSGeo community, I'm offering to help source extra 
terminology, but I don't want to start a new incompatible system. I'm 
hoping we can set up something which seamlessly integrates with ISO 211 
and OGC. And for that I'm asking for help. Think about the reality of 
sourcing terms from thousands of individuals. These people are not 
interested in managing a glossary, but would be fine with suggesting a 
missing term, or refining a definition - if we make the process easy.

So if you were to advise on setting up an OSGeo Terminology system from 
scratch what would you suggest? I'm thinking advice should cover 
crowdsourcing information, include a review process, and particularly 
pertinent to the OGC, should describe seamlessly integrate into OGC and 
ISO 211 systems (because we have agreed on the same field names and 
complementary processes).

Note: In my first 30 sec look I can see there are gaps in OGC 
definitions. I can't find an edge case word "GeoJSON", but can find a 
similar transport format "XML".
I can't find package names such as "QGIS". I'm sure there are more. I 
feel the OSGeo community could complement OGC hugely in supporting the 
spatial community around terminology - and we would be so much better 
with OGC's help.

After collating your thoughts, I suggest we should follow up with a 
video conference call.

Sound good?
