    Kerry: patent call

    <phila> [9]Patent Call

       [9] https://www.w3.org/2015/spatial/wiki/Patent_Call

    <KarlG> I'm new

    Kerry: anyone new ?

    <kerry> +q

    <kerry> -q

    <KarlG> +q

    Karlg: works at Standford U - Space & Time modelling interests

F2F Meeting

    <kerry> F2F meeting: call for presentations on GeoSPARQL,
    NeoGeo and the ISA Core Location vocabulary, GeoJSON,
    GeoJSON-LD and TopoJSON (for initial background, not for
    discussion)

    Kerry: Pin down agenda

    <kerry> [10]https://www.w3.org/2015/spatial/wiki/F2f_Barcelona

      [10] https://www.w3.org/2015/spatial/wiki/F2f_Barcelona

    Kerry: Please look - main job use cases review
    ... Scope Questions - Is this Use Case relevant re charter
    ... Next F2F item requirements then Use Case doc ready ASAP
    after meeting

    <Frans> I have volunteered!

    Kerry: 2 Editors Frans & Alejandro
    ... 3rd editor welcome

    <Alejandro_Llaves> Yup! Sorry, audio problems with my SIP
    client again...

    <Alejandro_Llaves> Agree!

    Kerry: Final item Presentations on Technology in Charter
    ... From people who know them..

    <MattPerry> +q

    Kerry: Edit wiki to add your technology presso

    MattPerry: Happy to do GeoSparql

    <JoshLieberman> Gotomeeting will also be in use at the OGC
    meeting. Could use this for a remote presentation...

    <JoshLieberman> Visual sharing was what I was thinking.

    Kerry: GotoMeeting & Zakim/IRC may cause confusion -
    Gotomeeting for video only

Scope Questions

    <kerry> Scope Questions: pls see and add to
    [11]http://www.w3.org/2015/spatial/wiki/Scope_questions_and_Req
    uirements

      [11] 
http://www.w3.org/2015/spatial/wiki/Scope_questions_and_Requirements

    Kerry: Idea to use q's to understand which parts of use cases
    are relevant
    ... To do before f2f meeting
    ... No time to present all use cases at meeting
    ... Editors write up review

    <Linda> i hear it too

    No we all hear

    <RaulGarciaCastro> too

    <Frans> same hear!

    Thats better

    <kerry> you cant hear me???

    <AndreaPerego> No

    <Simon> Was Kerry ??P1?

    <Frans> Perhaps Kerry was P1?

    <KJanowicz> No

    No can't hear kerry

    <kerry> i dont know why you cant hear me

    <kerry> i can hear you

    <kerry> i am hear -- i can hear you!

    <kerry> i am here - i can hear you!

    Kerry: Working from wiki page Q1 resolved - yes spatial data
    ... Happy to accept new proposals

    <kerry> Does the requirement encourage publication or re-use of
    data on the Web; (suggestion to be developed) Is the
    requirement testable? - can it be tested by machines, humans or
    a combination of the two. (suggestion to be developed) public
    vs private web (suggestion to be developed)

    <Frans> +q

    <JoshLieberman> Not sure #1 covers this "does the use case
    involve spatial enablement of Web data?"

    Frans: Most appropriate place for other questions?

    <JoshLieberman> +q

    Kerry: Wiki?

    Phila: Mailing list preferred - track discussions, recorded
    ... Mailing list also provides notifications

    Kerry: Transfer to wiki also

    Phila: And link in wiki to mailling thread

    <Frans> Linking stuff is always good

    Kerry: Need to restrict Use Cases to Charter
    ... Some duplication expected

    JoshLieberman: Wider area beyond spatial data on the web, can
    be given spatial content
    ... Clemens use case is good example

    Kerry: Propose new question ?

    <Simon> existential crisis

    Kerry: Frans q2 What does resolved mean ? - Agreed

    <LieberJosh> Does the use case involve providing a spatial
    context or component to existing Web data or content.

    Kerry: Q4 - Q2 and Q3 will help
    ... in resolving

    <ClemensPortele> +1 to adding Josh's question

    LieberJosh: GeoRSS as example - adding geometry to feature

    <Simon> Ping backs

    LieberJosh: Provide spatial context for other information water
    level in a lake for example

    Kerry: Reword ?
    ... Use case must meet ALL Questions

    <Frans> +q

    Kerry: Combine with q1? Data + Spatial content

    <aharth> +q

    <kerry> ack

    Frans: Use case real world problem - scope to requirements not
    use cases

    <KarlG> please unmute KarlG.a

    Frans: Scope helps in interpretation

    Kerry: Any one else on this topic ?

    <KarlG> +q

    <KarlG> please unmute KarlG.a

    <Frans> Maybe we can try out the scoping process on one use
    case as a test?

    <KarlG> question for Josh

    <aharth> -q

    KarlG: Q for Josh - spatial context is spatial data ?

    LieberJosh: Context not geometry

    <Simon> Geometry is a property or attribute, but is not a
    feature in its own right

    LieberJosh: Geometry is attribute

    <KJanowicz> focusing merely on geometry would be very
    reductionistic

    <AndreaPerego> +1 to KJanowicz

    <aharth> "context" may imply too much though, too broad a term

    LieberJosh: may want to link spatial object to different
    spatial geometry or reference for context

    <KJanowicz> what about platial data?

    KarlG: Spatial data definition is Broad enough

    <Frans> We may need a glossary page

    <Adila> +1 to KarlG

    <LarsG> +1 to Frans

    <KarlG> +1 to Kerry

    Kerry: OK to amend spatial data or context

    <Alejandro_Llaves> +1 to Frans

    <KJanowicz> +q

    <Zakim> phila, you wanted to wonder whether this is the Web/GIS
    split

    Phila: Interesting - problem with conceptual areas without
    boundary - little Italy for example
    ... Spatial context makes sense +Lieberjosh

    <LieberJosh> +1 for Phila

    <KJanowicz> Montello, Daniel R., Alinda Friedman, and Daniel W.
    Phillips. "Vague cognitive regions in geography and geographic
    information science." International Journal of Geographical
    Information Science 28.9 (2014): 1802-1820.

    kjanowicz: Not explicit spatial geometry

    +1 Phila

    <Simon> Names are the primary 'spatial' designator in the
    general community!

    <KarlG> placial? ;^)

    <KJanowicz> not about whether you like the term, I made the
    same argument as you did

    <CoryHenson> +q

    <phila> :-) KJanowicz

    <LieberJosh> +1 to spatial data or spatial context

    <KJanowicz> for most of the places we do not have an exact
    spatial representation

    CoryHenson: Spatial and Observations ? Observation out of scope
    ?

    <Simon> However, PhilA argument (you can put a name on a map)
    proves that place-name can be linked to a coordinate, even if
    it is merely 'centre of gravity' or similar

    <Frans> an observation can be of spatial nature. The observer
    can also have a location.

    Kerry: No SSN covers this

    <Simon> Cartographers have known this forever

    <KJanowicz> so if our SSN is part of 'spatial' then our
    definition is very broad anyway

    <LieberJosh> Observation actually has a multiplicity of spatial
    references, not a paucity

    Kerry: Don't want spatial but not temporal

    <Simon> If I understand correctly, Josh argument is that names
    can be linked to spatial coordinates, but often the link is
    maintained externally.

    <KarlG> this always happens to time

    <KJanowicz> +1 on spatial implies temporal

    <kerry> Is the use case specifically about Spatial data on the
    Web? (Resolved 29/1/2015)

    <Frans> In the locations and addresses group we hade a nice
    discussion about space and time. I send the link when I find
    it.

    <kerry> Is the use case specifically about Spatial data or
    spatial context on the Web?

    <AndreaPerego> Here it is:
    [12]https://www.w3.org/community/locadd/wiki/Space_and_Time

      [12] https://www.w3.org/community/locadd/wiki/Space_and_Time

    <Simon> @kerry - what am I supposed to be looking at?

    <LarsG> can we then say "spatiotemporal data or spatiotemporal
    context"?

    <kerry> Propose: is the use case specifically about Spatial
    data or spatial context on the Web?

    <KarlG> +1

    <Frans> I am not clear on the definition of spatial context.

    <kerry> +

    <phila> This would amend the resolution taken on 29 Jan - which
    is fine

    <Linda> +1

    <aharth> +1 with josh's description over the phone

    <LieberJosh> spatial data is feature data. spatial context is
    spatial reference attribute information separate from features.

    <aharth> context = feature or geometry

    Kerry: Not RESOLVED - discussion to be continued on the list

    <aharth> i can write a short mail

    <AndreaPerego> I'll explain my objection on the mailing list.

    Kerry: Add more scope questions please
    ... TIme zone changes start this week until end of april
    ... No changes to current UTC time

    <Simon> 5am meetings!!! Arrgh

    <ahaller2> -1

    Kerry: Will look again when all changes have worked through -
    end of April
    ... add time issues to list - Poll will not work
    ... Editor for use case still looking for more help
    ... Meeting closed

    <Simon> Coffee.

    <KJanowicz> bye, bye

    <AndreaPerego> Bye bye

    <CoryHenson> bye

    <LarsG> bye

    <Frans> to sleep!
