<SimonCox> Kerry having a go at 'sledging'
Patent call for OGC - any claims speak up !

<Frans> Link to the issue: http://www.w3.org/2015/spatial/track/issues/14
Frans to lead discussion
<phila> issue-14?
<trackbot> issue-14 -- Not clear Time req. - temporal reasoning and relations (xsd formats) -- open
<trackbot> http://www.w3.org/2015/spatial/track/issues/14
Frans: Issue 14 oldest issue - Req
<Frans> New requirement: "OWL Time should be updated to conform to the 2012 update of OWL datatypes."
Frans: Happy to vote on new req at this point
<SimonCox> ... however, OWL-Time already uses non-OWL datatypes as well, so has the horse bolted?
Frans: 3rd Req temporal relationships related to OWL time
<Frans> Possible new requirement: "There should be support for temporal relationships (Allen's interval algebra)."
Frans: Discussion already in OWL time does this need to be an additional req ?
<kerry> suggest change owl datatypes to xsd datatypes in requirement
Kerry: XSD data type as suggested by simoncox
<phila> XML Schema Part 2: Datatypes Second Edition
<phila> W3C Recommendation 28 October 2004
Simoncox: Just pointing out the confusion in OWL 2.0 time, one XSD was accepted - but not yet consistent
Kerry: Should allow for updates to OWL time and XSD
<SimonCox> http://www.w3.org/TR/xmlschema11-2/
Simoncox: XSD latest link posted
Frans: Suggested Req please in IRC ?
Phila: New datatypes OK, but not extending XSD ?
<SimonCox> 1. There is an alignment issue to be resolved or at least clarified
<Frans> How about "OWL Time should be updated to conform recent changes in related standards (e.g. OWL and XSD)"
Kerry: OWL time has some of XSD types - but old XSD data types
<SimonCox> 2. nevertheless, OWL-Time relies on a 'temporal reasoner' so already goes beyond OWL.
<kerry> OWL Time should be updated to consistent to the 2012 update of OWL datatypes and 2012 update of xsd datatypes
Kerry: Proposal above...
<phila> PROPOSED: OWL Time should be updated to align with the 2012 update of OWL datatypes and 2012 update of xsd datatypes
<ahaller2> +1
<LarsG> I guess that a requirement to update OWL DL to accept further temporal datatypes is out of scope for this group...
Phila: Make sure backwards compatible

<phila> RESOLVED: OWL Time should be updated to align with the 2012 update of OWL datatypes and 2012 update of xsd datatypes
Kerry: Do we need temporal
relationships ?
... Does not think so..
Frans: Agreed sets Dangerous precedent
Chris muted
<SimonCox> Perhaps acknowledge that Allen's temporal relationships are already in OWL-Time, bound to the class 'ProperInterval'
ChrisLittle: Jump from time coordinates to calendar could be a mess
Kerry: proposal to avoid ?
Chrislittle: OGC working on a BP
Kerry: Time special meeting in the future ?
Chrislittle: Chris Tucker might be interested
Chris tucker of Map Story
<kerry> https://www.w3.org/2015/spatial/wiki/BP_Consolidated_Narratives
Kerry: Intro end of last
week
... Next steps requested by Jeremy
... "cross-reference these common themes with those in the Data
on the Web Best Practice (editors draft) to determine overlap
(if any) - we want to avoid duplication
"
<joshlieberman> kerry, please post link again. irc froze on me.
https://www.w3.org/2015/spatial/wiki/BP_Consolidated_Narratives
Kerry: Second task "make sure we are consistent with the Architecture of the web (Volume One)"
<ahaller2> what is the deadline for that?
Kerry: Everyone clear ?
Volunteers ??
... Deadline next week
... Not a big job..
Billroberts: Can you clarify tasks ?
Kerry: Next steps 1 + 2 in Doc, and cross reference links to bottom of doc
<ahaller2> i volunteer for assignment of identifiers to ‘real-world things’ & information resources
<phila> http://philarcher1.github.io/dwbp/bp.html#DataIdentification
Phila: Approach taken by other group
<billroberts> I'll put my hand up for "publishing data with clear semantics"
Phila: Begins with general
blub... Defining URI's etc
... Links to BP elsewhere... for example persistent URI's with
examples.
... More to add not specifically real world objects - but
discuss later
Kerry: need to track changes of external links
<Linda> I volunteer for 'enabling discovery'
Phila: F2F next month, BP stable by TPAC
Kerry: By next monday if
possible,
... Linda - discovery, Bill Publishing, Armin IDs ?
<phila> DWBP
Phila: Main Doc link..
Kerry: expressing geo /temporal info anyone ?
<ChrisLit> me for temporal
<phila> Something else, ahaller2, see http://www.w3.org/wiki/HttpRange14Webography... and weep
<ChrisLit> Ok
Kerry: Exposing Data via API's
?
... Linking data ??
... Task to cross reference from other documents
<ChrisLit> me/ I will be on leave, offline, next week too
Kerry: please try to complete by
next week
... others if you can add your name - I will pick one
eparsons: data via API's
Kerry: I will do linking datat
<Frans> I have a general question about the BP deliverable
Frans: General question - Top down approach from narratives - what about bottom up writing up a single BP to start ?
Kerry: Not top down - analysis of
use cases thus bottom up - editors choice to do this but could
be possible
... Sapporo - SVG discussion and WoT lined up
... Interactions with other groups important
... Please register ASAP
ChrisLittle: SVG might be a year away from Geo use..
<SimonCox> Also note that there is a 1.75hr SDWWG session at upcoming OGC TC meeting - Nottingham 2015-09-16T13:00:00 (Wednesday afternoon)
<joshlieberman> Best practice is best derived from practice...
<SimonCox> http://www.opengeospatial.org/events/1509tcagenda
Kerry: May also have SDWWG at Sydney OGC TC
<phila> http://www.opengeospatial.org/events/1509tcagenda
Phila: Suggestion to align call with TC meeting
Kerry: Thank you all will add actions to tracker
<phila> Meeting at Nottingham TC would start an hour earlier than normal and last 2 hours
Bye !!
<billroberts> thanks bye
<joshlieberman> bye
<Linda> bye!
<Kostas> bye!
<ChrisLit> apologies for next week
