At the TAG we held a session to debrief from the OpenAg IATI Tool Accelerator (catchy title, I know) event we held in London, over four days in Feb 2017.
I tried to tell the story of the event through tweets people made (which is also interesting in terms of many perspectives that can be gathered, after the event)
We quickly got - I think - to an important point: just making space for people to get together is an important thing, but also quite difficult. In the London event, we made sure we could bring in some of the key people making tools around IATI, but also worked to ensure that the environment, dialogue and learning opportunities were optimised.
In the session at TAG we were very keen to avoid the idea of a "flying circus" of IATI wonks turning up on spec, and talking/doing IATI - so many people expressed a preference for establishing a local/regional TAG. I'll even say that @YohannaLoucheur and @siemvaessen volunteered their locales!
In terms of stimulus for these groups, we ranged between "open space" (turn up and just organise) through to the "global list of things that need fixing in IATI" (people organise to fix them), which also seems important. I dont think there will be a fixed formula or set menu for any group to follow. What will be important is visibility, transparency and sharing between communities - hopefully as they grow and diversify.
