I'm reading through these dates, looking at the calendar and only counting
3-weeks until we're supposed to be done (including this week).

Looking at the Detailed Plan [1] for this sprint (agree during Delft F2F)
that's about one-week too short.

Phil / François / Scott ... please can we have an extra week (e.g. to
"freeze" for a vote to release on, say, Friday 21-April)? This should still
leave enough time to get the doc published via both W3C and OGC in time for
presentation to the OGC TC by 12-May.

At tomorrow's sub-group call, we're (mainly) doing planning. Knowing our
target date would be very useful.

Another hello to you,

Based on the timeline provided below from Francois, here are the key OGC
milestones required to reach a 30 June 2017 publication date.

Best Practices

21 April - post of Best Practices to OGC Pending Documents: no major
changes allowed after this date
12 May - webinar to present Best Practices to Technical Committee (TC)
14 May - start TC recommendation vote (45 days)
30 June - Planning Committee (PC) approval at face-to-face meeting in St.


The W3C Recommendations cannot be approved as OGC standards by this
deadline. The process takes approximately 120 days once a stable version is
posted for review. What I recommend are the following milestones, starting
with the 14 April Last Working Draft.

14 April - submit document to OGC Architecture Board (OAB) for review
2 May - OAB review
3 May - start Public Comment (30 days)
15 May - finalize document with synchronized comments from W3C and OAB
2 June - assess whether public comments impact document
early June or 29 June - present standard to TC and request start of
electronic vote
middle to end of August - TC and PC votes complete and standard can become
official in OGC

Note that the Recommendations could also be published as OGC Best Practices
and later advanced as standards to meet the deadline.

thought it would be good to make deadlines clear for everyone, especially
for specifications that are to be published as W3C Recommendations (the SSN

constraints imposed by the W3C Process.

June 2017 to finalize on-going deliverables. Even if the group can
demonstrate progress, it is unlikely that it can get another extension for
the exact same reason after that. In other words, all documents should be
done by end of June 2017. Now, we may be able to negotiate that "done" can
be interpreted as "nearly done". Keep in mind that the following proposed
timeline already takes that into account and actually ends after June 2017!

get back to you within two weeks. Given the specifications, comments from
horizontal reviews should be minimal, so hopefully we'll be able to conduct
all reviews within a month timeframe.

This usually takes two weeks, sometimes less. The group should start to
work on filling out the implementation report in the meantime.
