1) Review the extent to which domain-specific or open-ended elements of SSN should be extended, possibly by reference to external ontologies (skos-like vocabularies) as exemplars, or by small additional components.
21:07:20 [frans]
2) Model tasking, programming and actuation of sensing devices.

frans: talking action-111- original use cases. Requirement 2- do you agree that it is a good requirement? Is something required by the outside world?

ack ahaller2
21:10:28 [kerry]

21:12:07 [kerry]
21:12:16 [JRamsay]
...not 100% comfortable with translation to requirements, what to look to.
21:12:59 [JRamsay]
frans: lots of requirements for best practices also are very general
21:13:42 [kerry]
21:13:48 [JRamsay]
... this particular one looks rather specific to SSN

21:14:52 [kerry]

21:18:08 [ahaller2]

21:18:36 [JRamsay]
ahaller2: for first requirement- a little abstract?
21:18:54 [ahaller2]
+1 for 2nd requirement

resolved: ucr doc to incorp requirement for actuation

Is it a requirement for examples that show how ssn can be used?
21:20:53 [JRamsay]
Kerry: yes, this has all sorts of things of people wanting on advice on how to do things that SSN may not do itself. May not need to be a requirement. Could be best practice
21:20:56 [kerry]
21:21:04 [kerry]
ack ahaller2
21:21:05 [frans]
Then I think is is a good and valid requirement

phila: things are being discussed in two places- github and issue tracker. This is a problem for archiving.
21:25:53 [JRamsay]
... github doesn't have a pledge for archiving
21:26:34 [ScottSimmons]
21:27:10 [JRamsay]
... all conversations should be recorded and archived. Whole group should know what is happening. Not everyone sees github..
21:27:59 [kerry]
ack ScottSimmons
21:28:06 [ChrisLittle]
+1 to discussions on mailing list. Docs on GitHub
21:28:10 [JRamsay]
... discussion specific to doc itself can go on github
21:28:42 [kerry]
21:28:42 [JRamsay]
ScottSimmons: OGC has the same policy.
21:29:52 [JRamsay]
Kerry: I also think that is is important to use mailing list to include the rest of the sdw working group
21:29:55 [kerry]
21:30:45 [kerry]
21:31:16 [JRamsay]
ahaller2: Thats okay. some things are just much easier on github.
21:31:55 [SimonCox]
21:31:59 [JRamsay]
phila: just be aware of the audience. If the issue is better discussed on github, do that, but consider mailing list first.
21:32:51 [JRamsay]
... when chair is looking at issues in meetings, look at github also?
21:33:57 [JRamsay]
... we don't want to be dictatorial. As long as everyone is aware, thats the important thing.

issue-73 -- Ssn group needs to produce a wiki document that realtes to requirements met or not from ucr -- raised

21:35:42 [JRamsay]
topic: UCR - reviewing for SSN requirements issue-73 and (Kerry)
21:37:52 [JRamsay]
Kerry: anybody who is happy to look through the UCR doc to analyse from W3C working group perspective?
21:38:54 [frans]
editorĀ“s draft of the UCR doc:
21:39:58 [kerry]
action: roba to review UCR doc from an SSN viewpoint -- is it complete and correct?
21:39:58 [trackbot]
Created ACTION-195 - Review ucr doc from an ssn viewpoint -- is it complete and correct? [on Rob Atkinson - due 2016-08-30].
21:40:00 [JRamsay]
roba: The comments I've made previously still haven't been mentioned in there, and are key concerns for spatial data. Is a challenge though.
21:40:35 [JRamsay]
... I'm willing to give this a review, but I need to understand better how to do this.
21:40:39 [kerry]
21:40:56 [SimonCox]
roba: UoM & precision are relevant to many UCs - probably a BP issue rather than narrowly SSN?
21:42:30 [JRamsay]
roba: if we are keeping the integrity, we need to make sure it gets into the use case requirements
21:44:02 [JRamsay]
phila: we will need a table in the doc that says how we met the requirements, or why they aren't relevant to address.

frans: it is probably out of scope for spatial data.
21:44:52 [kerry]
21:46:56 [JRamsay]
My audio just dropped out for scribing the last 30s. Anyone catch that?
21:47:27 [kerry]
roba: precision and uom needs to be pushed inot one or more of our deliverables
21:47:34 [kerry]
21:47:46 [SimonCox]
(talking about internationalization, ISO standards allow for the French-style decimal point indicator - comma vs. period!)
21:48:02 [JRamsay]
21:48:48 [JRamsay]
roba: is it BP or SSN?
21:49:03 [JRamsay]
Kerry: Both
21:49:27 [frans]
21:49:35 [kerry]
ack frans
21:49:38 [SimonCox]
phila: expressing quantity (or 'measure') as number+uom is like internationalization ...
21:50:03 [SimonCox]
21:50:14 [JRamsay]
frans: many requirements just come from doing things the way you are meant to do them

21:52:10 [kerry]
21:52:10 [JRamsay]
SimonCox: there is similarity between CRS and UoM.
21:52:15 [frans]
But CRS is really spatial
21:52:22 [kerry]
21:52:40 [JRamsay]
... the pattern is the same.
21:53:24 [kerry]
21:54:03 [kerry]
roba: suiggests tweaking the CRS ucr to include uom and precision....
21:54:19 [ChrisLittle]
21:54:38 [kerry]
21:55:20 [kerry]
issue: that uom and precision should be covered in UCR and BP (and respected in other deliverables too)
21:55:20 [trackbot]
