    Resolved

    <kerry> ttps://www.w3.org/2015/spatial/wiki/Patent_Call

    Kerry: patent call

    <kerry> resolved: accept last weeks minutes

    Kerry: Test of webex from Frans..

    Frans: Press "Share my screen and chose app"
    ... Also able to share single window..

    <billroberts> looks good to me

    <AZ> I see all the window fine

    <MattPerry> I can see it

    <Linda> looks good

    <Rachel> looks fine for me

    Frans: Presentation - publication of 700m triple dataset
    ... Metadata exposed as html metadata witch spatial aspects
    ... Spatial data uses Dublin core location subject, not at best
    practice as such could be standardised ?
    ... Spatial coverage predicate used - extent as geometry as
    GeoSparql
    ... Geometry expressed as Lat/long in WGS84 transformed from
    Dutch National Grid
    ... Current standard prefer WGS84 it seems ( Default ? )
    ... WKT needs CRS ref to be stripped
    ... WGS84 OK for this applications level of accuracy - Higher
    accuracy cm's would be difficult !!
    ... Need to indicate type of data e.g. Vector
    ... Need to also express resilution
    ... Not currently possible would be useful..
    ... Metadata also includes sparql endpoint so possible to
    querry
    ... Geometry allows geocoding...
    ... Spatial functions supported including creation of a point
    from Coordinates - could be used for a "where am I" app on a
    mobile phone
    ... Use of Virtuoso tool has some limitations
    ... Demo of query to return addresses with postal code - uses
    semantics from BAG vocab

    <ErichBremer> Any thought to relative spatial data? For
    example, a symbolic WKT polygon that uses URIs of things as
    coordinates and that the actual coordinates are attached to
    those URIs instead of coded onto the WKT string itself?

    Frans: Demo of query of global semantics alongside national
    vocab based semantics

    Kerry: Questions

    <ErichBremer> see mine

    ErichBremer: Relative spatial data URL's as coordinates ?

    Frans: This would be a mutation is coords changed - new object

    Kerry: URI for everypoint ?

    ErichBremer: No URI attached to triangle symbolic link

    billroberts: Nice illustration - lots of ways to express
    spatial in RDF - but too many !!
    ... How to chose whats appropriate is a challenge

    Kerry: Quality of presso ?

    <ErichBremer> and link to the data?

    aharth: Nice to have presentation linked to wiki

    kerry: important for people who can't get webex to work

Use case timeline to First Public Working Draft

    Kerry: Agenda switch - use case timeline propsoal
    ... Need to move fwd on use cases need help from group to
    complete
    ... Dedicate next meeting to this.. 3rd June vote to progress
    doc to first public working draft
    ... This has more status
    ... Group needs to agree to this - as we take ownership of it
    at this point

    <AZ> A FPWD has a permanent URL and a fixed date of
    publication, while an ED has one URL for a document that
    changes all the time

    Kerry: Allows us to move on to BP Doc
    ... According to charter already a year late
    ... Think this is achievable any comments ?

    <kerry> topic; Use Case Actions

use case actions

    Kerry: Lots of Actions now on tracker...
    ... Using w3c tracker at the moment...

       [9] http://www.w3.org/2015/spatial/track/users

    <kerry> action-28 close

    Alejandro_Llaves Finished coverage transfer to html - Next
    phase to collect issues and comments that need group
    disscussion

    Alejandro_Llaves move these to tracker

    Kerry: will also cover next week
    ... Added new comments when making changes to Use Cases

    Alejandro_Llaves New reqs need to be added therefore

    Alejandro_Llaves: Like people to check for missing reqs and add
    comments in spreadsheet

    Kerry: Pick on Someone else with actions.. Mattperry

    Mattperry: UC 16 can be closed

    <kerry> close action-15

    <trackbot> Closed action-15.

    <kerry> close action-27

    <trackbot> Closed action-27.

    billroberts: Action 27 is duplicate of 18 both to be closed

    Frans: Action - work in progress

    Kerry: Leave principles stuff out ? Does this work ?

    Frans: associated email thread needs to be worked through

    Kerry: bring back next week
    ... Last 5 mins any other issues to do for use case ?

    Frans: Creating issues in tracker works well
    ... Happy !!!

    Alejandro_Llaves: How do we review as a group html doc before
    it becomes First Working Draft
    ... Appreciate wider review before this step..

    <AZ> My experience in previous groups: two reviewers within the
    group provide comments

    Kerry: Editors can ask one or two people to review...

    <AZ> about the editorial draft

    Kerry: Editors need to set the time

    Alejandro_Llaves: Some people have more expertise , so editors
    can select appropriate people

    <Alejandro_Llaves> of course, volunteers for reviews are
    appreciated!

    Frans: Technical talks ?

    Kerry: Not for next few weeks

    <Alejandro_Llaves> the idea would be to look at the different
    use cases for a specific deliverable, check the description,
    working links, etc.

    Kerry: Thx Frans

    <Alejandro_Llaves> thanks, bye!

    <ErichBremer> thank you

    <LarsG> thanks, bye

    <Linda> bye

    <ChrisLittle> bye

    <Rachel> thanks, bye

    <Ian_Holt> Thanks

    <AZ> bye

    Thanks all - bye
