International interoperability

Dear Sam, all,
I am fully aware of the openEHR efforts, CKM etc. I agree that these are 
platforms are required !!! to get the work done.

My point is that interoperability will only work for users / systems who 
are represented in the discussions. Those  who engage and agree on 
harmonised solutions will have interoperability. "The rest of the world" 
are not represented, they do not discuss. We cannot solve their problems 
for them. The "rest of the world" will therefore not have 
interoperability (with us) without further work.

Limiting the scope to a certain user group and a use case will make 
harmonisation crisp and easier.  We can focus on solutions for those who 
are represented in the discussions and get those going. We can then 
prove and disseminate to "the rest of the world" that this works 
elegantly with little effort for a certain purpose in a certain 
community. Our experience in Austria is that "the rest of the world" 
will notice and jump on the train. The train needs to be there before 
anybody will jump on.

(I do admit that we do not see the complete "rest of the world" on our 
Austrian trains. But there is an audience and there is international 
cooperation with relevant groups elsewhere.)

(Online tools are fine. In my experience however harmonisation work is 
successful if you have at least a few face to face meetings at the 
start, but that is another story, does not belong here.)
