[occi-wg] OGF 42 OCCI Sessions - thank you & notes

[Metsch, Thijs]

Hi,

Thanks to all of you for helping the last weeks and months preparing the sessions we just had at the OGF 42 event in London. Also many thanks to those who attended in person. Again: it is the community who uses, lives and defines the standard :-)

Here are some rough meeting notes I took over the course of the OGF event. Excuses for the bit longer list - we had a total of 4 sessions with plenty of discussions.

Many thanks again,

-Thijs, Andy
