I believe we are supposed to publish another working draft before 
reaching CR status at the end of this year. If we want to give enough 
room for feedback I think we ought to do this soon after the upcoming 
virtual face to face meeting.

Looking at the list of open tickets, many are entirely editorial and 
others could be closed simply because we ran out of time and won't be 
able to give them justice (e.g. ISSUE-179, ISSUE-176). However, there 
remain some tickets with impact on the syntax and implementations:

ISSUE-92: partitions
https://www.w3.org/2014/data-shapes/track/issues/92
Eric promised to work on an update to the partition chapter. Without 
progress, I don't think we can include these features. We risk running 
out of time, and I want to be in a position where I understand all 
implications for an implementation (e.g. the potential worst-case 
complexity).

ISSUE-180: Path nodes.
https://www.w3.org/2014/data-shapes/track/issues/180
The suggestion is to change the path syntax so that IRIs are always 
named predicates while all path expressions (inverses etc) must be 
bnodes. I believe Dimitris and I agree on this change.

ISSUE-186: validation report properties.
https://www.w3.org/2014/data-shapes/track/issues/186
The suggestion is a simple vocabulary fix: 
https://lists.w3.org/Archives/Public/public-data-shapes-wg/2016Oct/0040.html

The latter two are hopefully easy to resolve in the next meeting.

A big unknown remains the topic of pre-binding (ISSUE-68 and ISSUE-170). 
The SPARQL EXISTS group seems to be making slow but steady progress, yet 
we need this done before we can move to CR.

BTW what ever happened to the Compact Syntax? It looks like we are 
running out of time and it won't happen. Maybe a differentiator for ShEx?
