Re: [cmis] Reference Implementation Considerations

["David Nuescheler" <david@day.com>]

Hi Dennis,

thanks a lot for your mail, I fully agree that this is probably not
TC business to begin with, but we might find a number of
parties interested in having these conversations in one
location around the F2F.

Great idea about the BoF.
I am happy to prepare and host a BoF around the F2F, nothing
formal just a brief initial conversation on the topic.

So if anybody is interested, please let me know, so I can schedule
something and find a suitable location depending on the size of
the group.

I think based on the excellent conversations on this list we should
have enough materials for a great agenda. ;)

Looking forward to meeting you in person.

regards,
david
