Re: [webvmt] Status Update

Hi Rob A, et al., 

Thanks for sharing/copying the SDW list on this note! 

Would you or one of the other SDW folks be able to join a GeoPose SWG meeting to discuss this “alignment” with our experts and work directly? 

Just FYI, we meet tomorrow at 10 AM Eastern, and are invited to join <https://us02web.zoom.us/j/87364754557?pwd=XXp6rRO9ZDTa6DKRY4iUuXVv7MME1G.1> to see what we’re up to/lurk. Unfortunately, our agenda (20 minutes of which will focus on our current work <https://geopose.org/CallForContributors.html>) is already spoken for. 

Maybe there’s an opportunity to present/discuss the wrapped GeoPose schema on May 9? 
Steve Smyth will chair/host the meeting as I’ll be traveling. 

Alternatively, understanding that you are in a time zone that is not friendly to 10 AM Eastern, we might explore finding another time of day for an informal “workshop” with stakeholders.

Thoughts? 

Best regards,
