next meeting


      [15] http://www.w3.org/2012/ldp/wiki/Use_Cases_And_Requirements

    Arnaud: next meeting is next monday, however we might have a
    summer schedule, as people take vacation

    <LeeF> I think we should keep the normal schedule.

    <rgarcia> +1 for summer schedule

    <cgueret_work> +1 to keep

    <svillata> +1 to keep

    <ericP> +1 to slacking

    <oberger> +1 summer schedule

    <Ruben> +1 summer schedule

    <cygri> +1 summer schedule

    <ghard> +1 summer schedule

    <oberger> (given that most are in northern hemisphere ? ;)

    Arnaud: July 9 then every other week until end of august ?

    <cygri> +1 to that

    <krp> +1

    <svillata> +1

    <rgarcia> +1

    <SteveS> +1 to Arnaud's proposed schedule

    <ghard> +1 every other week

    <Ruben> +1

    <cgueret_work> +1

    eric: missing one out of 3 is a sure way to be confused

    Arnaud: no objections?

    <cgueret_work> can we do anything for the time?

    noone screaming, so

    <cgueret_work> earlier or later?

    RESOLUTION: July 9 then every other week until end of august

    <cgueret_work> :)

telcon time

    Arnaud: telcon time. earlier or later?

    it's 7am in California, so doing earlier would be difficult

    <oberger> depends if summer siesta time ? ;)

    Arnaud: we tried a doodle with just 5 people, and even finding
    one slot was quite hard

    <cgueret_work> ok

    Yves: let's continue with this time and see if it works for
    most people or if too inconvenient

    Arnaud: it is customary with a WG to start with a f2f

    there is a notification period for F2F (because of travel

    the Technical Plenary once a year, for 2012 it's here:

      [16] http://www.w3.org/2012/10/TPAC/

    would people be able to attend that meeting?

    <SteveS> +1 I "should" be able to get to tpac but would
    recommend a 3Q F2F meeting 1st

    <JohnArwe> no known conflicts w TPAC for me

    <svillata> should be able to go to TPAC

    <ghard> Seems to work for me

    <cgueret_work> +1

    <Ruben> +1

    <oberger> +1 probably

    <antonis> +1

    <rgarcia> no conflicts for me "right now"

    <svillata> +1

    Erik: it's more up to the group to decide. at worst we can have
    a small group there

    SteveS: we could also do transatlantic f2f, with two locations

    <AndyS> was not me, was AndyS I believe

    Arnaud: if we get a transatlantic presence, it should be east
    soact US to reduce the time diff

    SteveS: having the first f2f in 5 monthes is a bit late

    Arnaud: the WG started right before summer, with lower
    attendance, so meeting in september while TPAC is in

    <ericP> -1 to sept f2f

    <AndyS> Notes on SPARQL Graph Store Protocol :


    AndyS: there are 3 protocols, issuing query, requests

    sparql update allows you to manipulate the graph store

    this is used for fined-grain graph control

    there is also bulk modification, like adding a graph store

    you can delete a graph

    the specification is just translating what HTTP says

    it defines POST of RDF data to add things to a graph

    you don't get hierarchy of containers, like stores of graph

    PATCH is proposed to mean a SPARQL update

    as in the first example, a URI can identify a graph in a graph

    a more complex example is doing indirect graph identification,
    using ?graph=<uri of the names graph>

    <ericP> <graphstore>?graph=[18]http://foo.example/graph1

      [18] http://foo.example/graph1

    POST to a graph means append, POST to a graph-store means
    create a graph

    Arnaud: do you have comments on how it compares to the IBM

    AndyS: the IBM submission has more complex things like what you
    put in containers

    in the SPARQL graph protocol, you only manipulate graphs in the

    there is only one case

    <Zakim> cygri, you wanted to ask about uptake

    cygri: how about implementations?

    <cgueret_work> Redstore implements it too:

      [19] http://www.aelius.com/njh/redstore/

    AndyS: Garlik is implementing it.

    <cgueret_work> I am

    LeeF: difficult to figure out all implementations

    <cgueret_work> but my mic does not work :/

    <cgueret_work> works fine

    <cgueret_work> sorry... :P

    <LeeF> We don't implement it all in Anzo but will be completing
    an implementation of it in the coming months

    <cgueret_work> (I use RedStore for a graph-centric data
    management stack and the graph protocol works just fine in it)

Annotea Protocol

    <ericP> [20]Annotea Protocol

      [20] http://www.w3.org/2001/Annotea/User/Protocol

    <ericP> [21]Linked Data API

      [21] http://www.w3.org/2012/Talks/0717-egp-API4KB/#%284%29

    <AndyS> Linked data API:

      [22] http://code.google.com/p/linked-data-api/

    <AndyS> implementation:


    the main difference with LDBP is the link list (next/prev ones)

    provides random access in a big container

    <SteveS> +q Was Annotea adopted? what happened to it after it
    was published?

    <AndyS> app using LDA:

      [24] http://environment.data.gov.uk/lab/bwq-web.html

    <AndyS> (and I'm watching the server stats :-)

    it's using URI templates

    short-string to predicate mapping

    <ghard> FYI: Virtuoso has some support for HTTP CRUD operations
    for graphs as well. Uses special endpoint /sparql-graph-crud

    EricP: annotea was mostly a demonstrator, paired with Amaya to
    show annotations
    ... it's just a random document, not a Team Note

    Arnaud: scribe duties is a shared responsibility, so we will
    start a scribe list

    default order will be alphabetical list

    <cgueret_work> +1 for alpha list :)

    next meeting in two weeks.
