12:07:47 <simonstey> two PRs defining the auto-publish workflows for node-expr and rules: https://github.com/w3c/data-shapes/pull/741 https://github.com/w3c/data-shapes/pull/740
12:07:55 <Robert> simonstey: discussing auto-publishing
12:08:00 <TallTed> Please update calendar for UI task force
12:08:26 <Robert> ... also auto-publish all task force work, e.g. node expressions, rules, ...
12:08:49 <Robert> .. Carine set up the auto publishing.
12:08:52 <AndyS> q+
12:09:42 <AndyS> q-
12:12:04 <Robert> simonstey: auto-publishing for sparql works
12:12:11 <elianaP> q?
12:12:21 <Robert> caribou: for publishing manually, then workflow can be set up
12:13:02 <caribou> s/for publishing/First Public WD is always published/
12:13:21 <Robert> TallTed: time in calendar for UI should be updated

12:14:04 <elianaP> q?
12:14:16 <Robert> AndyS: discussion for timelines
12:14:36 <Robert> ... chartered until end of this year December
12:15:27 <labra> labra has joined #data-shapes
12:15:29 <Robert> ... at least 4 months before end we should have a stable version.
12:15:42 <Robert> ... so implementers can pick it up
12:16:32 <Robert> elianaP: q1 to see what absolutely should be implemented
12:16:55 <Robert> ... have a plan until next month
12:17:36 <AndyS> q+
12:17:37 <Robert> elianaP: for core and sparql it should be fine
12:17:57 <Robert> ... for other parts, maybe risky timeline.
12:18:38 <Robert> AndyS: node expr and rules list/use a lot of functions
12:18:55 <Robert> ... implementation takes a lot of time
12:19:26 <simonstey> q+
12:19:35 <AndyS> ack me
12:19:54 <Robert> AndyS: maybe we don't need proof for every detail of implementation
12:20:10 <Robert> elianaP: but we need two implementations, right?
12:21:00 <Robert> simonstey: either implemented or not; how can we leave out parts?
12:21:20 <Robert> ... tests should cover it.
12:22:35 <Robert> simonstey: don't think we can leave out parts of the implementation
12:22:45 <caribou> q+
12:22:55 <Robert> elianaP: group functions and reduce workload
12:23:41 <Robert> simonstey: can we find a middle ground? are the already such cases?
12:24:22 <Robert> caribou: if we don't meet two implementations for some parts, we can mark them at risk
12:26:17 <Robert> ... for some features, implementers might not implement it at all -> mark it at risk.
12:26:57 <bergos> q+
12:27:40 <caribou> ack sim
12:27:43 <caribou> ack car
12:28:23 <Robert> AndyS: sparql picked up already defined functions
12:29:16 <Robert> ... which datatypes are expected to be supported?
12:29:46 <Robert> ... example duration: you need datetime + duration function
12:31:32 <Robert> elianaP: in the next months task force gorups should make a list of features and then look for parties to implement.
12:32:24 <Robert> bergos: Holger has the needed functions implemented, so we can reuse.
12:32:45 <Robert> ... core, sparql, node expr should be covered.
12:33:30 <bergos> ack me
12:33:38 <Robert> simonstey: people in the task forces can implement.
12:34:59 <Robert> elianaP: please update task force calendars
