Here’s a link to the notes which were made before and during the open space session on: Designing interoperable apps for the open app ecosystem.
You can also find background info on The Open App Ecosystem
And some more discussion about The Open App Ecosystem on Loomio
There’s also this great article introducing the idea of the Collaborative Technology Alliance
And info about the CTA “seal”
imho - our collection of communities should use the impetus from OPEN 2017 to help re-boot the CTA and to encourage uptake of the seal to further interoperability.
"Adopting the seal is an explicit pledge towards interoperability between our technologies and our communities"
