Thanks for that. Great diagram!

If I read it correctly the number of non-DiGIR (i.e. SOAP) providers  
is more than double the number of DiGIR providers so to say that  
speciesLink is DiGIR network is only describing the public facing  
part of it. In a way it is more like a SOAP network with a DiGIR  

I am currently putting together a series ANT build files with an  
AntForms interface for day to day use. It will effectively do the job  
of your Java client. I figured it was the easiest way to build  
configurable pipelines with some common components.

I intend to base the table structure on a TAPIR CNS. The CNS files  
effectively flatten the ontology into a table in a predictable way -  
but without the opportunity to have repeating properties. The server  
side tables can then have the same schema.

The only downside of this is the need to have a table for any one to  
many relationship such as multiple identifications of specimens.

I may put a wiki page on the TAG wiki about this if I get a chance as  
it would be good for people to share experiences and know what  
resources are available.

All the best,
