    <raphael>
    [12]http://www.w3.org/2008/WebVideo/Fragments/wiki/FirstF2FAgenda

      [12] http://www.w3.org/2008/WebVideo/Fragments/wiki/FirstF2FAgenda

    is the agenda ok and complete?

    no objections

    Monday will be mostly use cases

    please prepare some material for your use cases

    the discussion of the syntax will be on Tuesday

    jackjansen would like to swap the use cases around, because he can
    attend only on Tuesday

    proposes switch of discussion I and discussion III

    raphael is ok with it

    no further comments

    remember to prepare more details on your use cases

    please also enter into the wiki your arrival and departure times

ISSUES LIST

    action items to go through

    <trackbot> Sorry, couldn't find user - items

    Raphael to look into image maps spec re spatial fragment shape

    image maps allow several different shapes

    there are two types of image maps: client-side & server-side

    server-side image maps are done with queries ("?") but are not often
    used on the Web

    <Yves> server-side image maps were used back in 94/95, no longer now

    cleint-side image maps have as a draw-back the problem that they
    cannot be indexed by search engines

    the second action will be discussed during the F2F and thus
    documentation created

    <Yves> close ACTION-3

    <trackbot> ACTION-3 And Erik to document container formats closed

    Silvia has sent a long email and a sketch on how fragments and
    protocols can work

    she started with side conditions and then took into account all the
    different standards (HTTP, proxy, URI) that prvide restrictions

    Yves was to check the status of ';' in a URI

    he sent an email and found that ";" basically has the same
    restrictions as "?"

    <Yves> ACTION-5 closed

    <trackbot> ACTION-5 Check the status of ';' in a URI closed

    he is not sure how many other applications are using ";" for
    different purposes

    silvia mentions that we should check use of whatever syntax we
    decide upon by checking existing usage

    <Yves> [13]http://www.ietf.org/rfc/rfc3986.txt

      [13] http://www.ietf.org/rfc/rfc3986.txt

    Erik: ";" may be in use by others, too

    jackjansen: requested a reading list for the plane

    <Yves> Section 3.3 is the useful one, for ;

USE CASES

    * Media Annotation UC: [Silvia]

    Silvia focused on her action item

    will have more at the F2F

    * Media Delivery UC: [Davy]

    <Erik> Day, you have to speak louder

    Davy says we may only have to consider http

    raphael: can you investigate more for next week?

    * Media Linking UC: [Michael]

    Michael modified the UC a little

    added Bookmarking

    scribe: Playlists
    ... and interlinking

    possibility to get input from seesmic for these use cases

    Silvia wonders what we can get from seesmic

    WP plugin from Seesmic helps leaving comments

    Jack: Seesmic is more about chatting than blogging

    Silvia: yes, a "video twitter"

    Raphael: much links happening between videos in Seesmic

    Jack: they seem to still treat each session of video as a separate
    unit

    Raphael: probably only because of current technology limitations
    ... if they had temporal URI, they would use it

    Jack: ok..

    Raphael: let's discuss more at the F2F

    * Media Search UC: no volunteer

    * Media Browsing UC: no volunteer

    Raphael: may need input from the media annotations working group
    ... chance to meet them at TPAC to discuss more

    * Photo Book UC: [Erik]

    Erik will have something to present at F2F

    * Map and Multi Resolution UC: [Raphael]

    Raphael will have something to present at F2F

    scribe: with discussion of what technologies are currently used

    * Karaoke UC: no volunteer

    deferred

    * Moving Point of Interest UC: [Davy & Erik]

    relevant in second phase of WG

    nothing to report right now

    * Video Browser UC: [Silvia]

    will present something at F2F

    no further questions on use cases

STATE OF THE ART

    <raphael>
    [14]http://www.w3.org/2008/WebVideo/Fragments/wiki/State_of_the_Art

      [14] http://www.w3.org/2008/WebVideo/Fragments/wiki/State_of_the_Art

    ** HTTP/URI (Michael/Yves)

    ** RTSP Fragment (Silvia)

    ** SMIL (Jack)

    ** CMML (Silvia)

    ** MPEG-21 (Davy/Silvia)

    ** Spatial Fragment (Raphael)

    Issues page is mostly focused on HTTP/URI case

    Raphael: Silvia, would you like to add something to CMML

    <raphael> Jack: CMML relevant since it allows to attach annotations
    to media fragments

    <raphael> Silvia: small overlap

    Silvia: CMML relevant from the POV of naming segments in media files
    ... but the attachment of metadata, descriptions, timed text and
    outgoing hyperlinks are not that relevant to this WG

    Jack: curious to discuss at F2F

    <Erik> work hard :)

AOB

    no other business
