[Minutes-SSN] 2016-06-14

The minutes of this week's SSN Sub group meeting are at 
https://www.w3.org/2016/06/14-sdwssn-minutes in which you'll see that 
the discussion was actually about OWL Time, not SSN :-)

Vote on publication of the draft (http://w3c.github.io/sdw/time/) 
imminent - maybe in next week's plenary.

Text version of the minutes below.

OWL-Time: Editor's walk-through: see ed draft

    <SefkiKolozali_UniS> Kerry: we are planning to catch the
    deadline to publish ssn by next week. OWL-time has been around
    for 10 years.

    <SefkiKolozali_UniS> Simon: Simon has presented OWL-time. He
    said Section 2 shows the changes from previous changes. So far
    the only modifications have been made is the changes addressed
    in the journal paper Simon has authored. Simon has embedded
    some issues into the web page. Section 4 is a preliminary
    overview.

    <SefkiKolozali_UniS> Simon: There are two subclasses of
    TemporalEntity class, namely interval and instant.

    <DanhLePhuoc> [12]https://www.w3.org/community/rsp/

      [12] https://www.w3.org/community/rsp/

    <SefkiKolozali_UniS> DanhLePhuoc has reported that time
    overlapping property is a general concern for people who work
    in stream processing field. It needs to be further developed to
    help researchers to describe events in more detail.

    <SefkiKolozali_UniS> Kerry: OWL-Time is good enough to deal
    with stream reasoning, and there are a couple of good
    implementation solutions to overcome concerned problem without
    having a need of modification of OWL-Time.

    <Kerry> ACTION: danh to investigate needs for temporal
    relations in stream reasoning to consider for owl-time

      [13] http://www.w3.org/2016/06/14-sdwssn-minutes.html#action01]

    <trackbot> Created ACTION-179 - Investigate needs for temporal
    relations in stream reasoning to consider for owl-time [on Danh
    Le Phuoc - due 2016-06-21].

    <Kerry> issue: do we need to add rules to owl-time to support
    stream reasoning - realtes to action-179

    <trackbot> Created ISSUE-68 - Do we need to add rules to
    owl-time to support stream reasoning - realtes to action-179.
    Please complete additional details at
    <[14]http://www.w3.org/2015/spatial/track/issues/68/edit>.

      [14] http://www.w3.org/2015/spatial/track/issues/68/edit

    <Kerry> ACTION: sefki to check through defintions of intervals
    in owl-time [recorded in
    [15]http://www.w3.org/2016/06/14-sdwssn-minutes.html#action02]

      [15] http://www.w3.org/2016/06/14-sdwssn-minutes.html#action02]

    <trackbot> Created ACTION-180 - Check through defintions of
    inteval relations in owl-time [on Sefki Kolozali - due
    2016-06-21].

    <SefkiKolozali_UniS> Simon has asked for a help for someone to
    look into the definitions of interval properties. Sefki has
    accepted to check it.

    <SefkiKolozali_UniS> Simon: the original owl-time schema was
    based on xml:date time but there is a small room for
    improvement. It is now based on single calendar, and it needs
    to be extended to support different calenders.

    <ByronCinNZ> Isn't TRS analogous to CRS? Can we use similar
    approach?

    <Kerry> that gendattimedescriptionbecomes
    generaldatetimedescription

    <Kerry> gendatetimedescription?

    <Kerry> generaldatetimedescription?

    <Kerry> +1

    <ClausStadler> +1 full name preferred as well - gen also
    overlaps with e.g. generator ;)

    <SimonCox> General +1

    <DanhLePhuoc> +1 full nam

    <SefkiKolozali_UniS> There has been a discussion to replace the
    word "Gen" with its full name "General" between Kerry and Simon

    <Kerry> +1 to that approach for trs

    <DanhLePhuoc> +q

    <ClausStadler> While we are at naming: was hasTRS already
    present in owl time so far? if not, maybe a full name or the
    abbreviation might be more intuitive? -> temporalRefSys,
    spatialRefSys

    <SefkiKolozali_UniS> Simon: Issue 7 was to trigger a discussion
    on temporal reference system on the ontology. However, he
    hasn't received a response from the group yet.

    <SefkiKolozali_UniS> DanhLePhuoc has asked a question about the
    time zones. Simon said that it is a separete subject as it is
    subproperty of gregorian clock system and has not worked on it
    yet.

Prepare for W3C FPWD and OGC discussion paper on OWL-Time vote next
week

    <SefkiKolozali_UniS> Simon: OWL-Time now supports Unix and GPS
    time
