    <Chris> Meeting: WebCGM WG f2f, Cologne

    <lofton> Scribe: Dave

    <lofton> Scribenick: dc

    <lofton> Scribes chosen for Session 1-6: Dave, Don, Benoit, Thierry,
    Chris, Stuart

Welcome, Logistics, Week's events, Review agenda

Review Goals

    <Chris> The goals sound good to me

    <Chris> LC= Last Call. CR = Candidate Recommendation

    finalize LC processing

    schedule CR spec production

    finalize agreement on CR exit criteria

    look at implementations and test suites

    plan & agree CR/PR schedules

    (start) prepare CR transition materials

    Webnesday afternoon we will have a telecon with the inplementers not
    present

Last Call processing

    <Chris> I reminded WAIPF about an outstanding review

    <thierry> Disposition of comments for WebCGM 2.0 Last Call

    <thierry>
    [14]http://www.w3.org/2006/07/03/WebCGM2-LastCallResponses.html

      [14] http://www.w3.org/2006/07/03/WebCGM2-LastCallResponses.html

    All last call comments received to date have been resolved

    May still get comments from WAIPF

    but as we move to CR processing we have a choice of how we deal with
    them

    two loose ends from internal discussions

    1. namespace defintion

    2. Benoit's rewording of highlight description

    namespace URI comment url

    System identfiercurrently in WebCGM 2.0

    [16]http://docs.oasis-open.org/webcgm/v2.0/webcgm20.dtd

      [16] http://docs.oasis-open.org/webcgm/v2.0/webcgm20.dtd

    We seem to be ok to keep the URI the same

    We seem to be ok to keep the Public and System identifier the same

    The dereference document should reflect the doublicity of the
    specification with both W3C and OASIS

    <scribe> ACTION: Chris to communicate with directory with namespace
    uri and identifiers [recorded in
    [17]http://www.w3.org/2006/08/23-webcgm-minutes.html#action01]

    <trackbot> Created ACTION-8 - Communicate with Director with
    namespace uri and identifiers [on Chris Lilley - due 2006-08-30].

    <lofton> current NS URI: [18]http://www.cgmopen.org/schema/webcgm/

      [18] http://www.cgmopen.org/schema/webcgm/

    Resolution: adopt WebCGM namespace for all versions of

    Namespace URI discussion complete

    BB - focus on object behavior to resolve this question

    BB - if you highlight an object, does the highlight propagate to
    children objects?

    WebCGM 2.0 reference:

    [21]http://www.w3.org/TR/2006/WD-webcgm20-20060623/WebCGM20-IC.html#
    webcgm_3_1_2_4

http://www.w3.org/TR/2006/WD-webcgm20-20060623/WebCGM20-IC.html#webcgm_3_1_2_4

    <Chris> void highlight(in WebCGMNodeList nodes,

    <Chris> in boolean state);

    <Chris> void highlight(in WebCGMNodeList nodes)

    <Chris> void clearHilight()

    <Chris> replace the first one (from the spec) with the two methods.
    one to add hilighting and one to clear it all

    <Chris> perhaps change the method name to addHilight

    <Chris> This makes the DOMmatch the object behaviors

    Currently the DOM doesn't match the description of the object
    behaviors

    Agreed that when an object is highlighted, all of it's children
    highlight

    Resolution: Acept Chris' proposal

    <scribe> ACTION: Editor to revise the document and the IDL [recorded
    in [22]http://www.w3.org/2006/08/23-webcgm-minutes.html#action02]

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

    <scribe> ACTION: Lofton to revise the document and the IDL [recorded
    in [23]http://www.w3.org/2006/08/23-webcgm-minutes.html#action03]

    <trackbot> Created ACTION-9 - Revise the document and the IDL [on
    Lofton Henderson - due 2006-08-30].

    <scribe> ACTION: Stuart to update the highlight test in the TS to
    reflect this decision [recorded in
    [24]http://www.w3.org/2006/08/23-webcgm-minutes.html#action04]

    <trackbot> Created ACTION-10 - Update the highlight test in the TS
    to reflect this decision [on Stuart Galt - due 2006-08-30].

    <lofton> (....morning break....)

    highlight behavior discussion complete

Begin CR discusions

    item left over from first previous topic

    Should we process an erratum to deal with changes to URI/IRI for
    WebCGM 1.0?

    Chris - this is probably a good idea

    Timeline for CR Draft

    thierry - need a minimum date for exiting CR to put into the Status
    of This Document (SOTD)

    <tmichel> WebCGM 2.0 CR version cover page.

    We will need to pass a resolution in the WG if we want to transition
    to CR

    At that point we will need a conference with the director for
    approval to publist the CR

    This conference requires a 1 week lead time

    Best case - we have a Friday resolution and the document ready to go
    at that time

    Best case conference with director would be Tuesday September 5

    One month duration would be October 5

    Before entering CR we would need a draft implementation report

    Transition requiements for CR

    *dc test

    <Chris> From SVG spec:

    <Chris> When two line segments meet at a sharp angle and miter joins
    have been specified for 'stroke-linejoin' , it is possible for the
    miter to extend far beyond the thickness of the line stroking the
    path. The 'stroke-miterlimit' imposes a limit on the ratio of the
    miter length to the 'stroke-width' . When the limit is exceeded, the
    join must be converted from a miter to a bevel.

    <Chris> <miterlimit>

    <Chris> The limit on the ratio of the miter length to the
    'stroke-width' . The value of <miterlimit> must be a number greater
    than or equal to 1. Any other value shall be treated as unsupported
    and processed as if the property had not been specified.

    <Chris> The ratio of miter length (distance between the outer tip
    and the inner corner of the miter) to 'stroke-width' is directly
    related to the angle (theta) between the segments in user space by
    the formula:

    <Chris> miterLength / stroke-width = 1 / sin ( theta / 2 )

    <Chris> For example, a miter limit of 1.414 converts miters to
    bevels for theta less than 90 degrees, a limit of 4.0 converts them
    for theta less than approximately 29 degrees, and a limit of 10.0
    converts them for theta less than approximately 11.5 degrees.

Initial telecon with implementors

    <thierry> Pass all tests exept 6 tests:

    <thierry> Interested in 2.0 test suite result, but we are now
    interest into 1.0 tes

    <Chris> linecap 1 and 2, linejoin

    <Chris> miter limit

    <Chris> 2 pattern tests

    <Chris> sizing of the pattern is not correct

    <Chris> everyone seems to pass the values tomicrosoft gdi so they do
    not get the correct result

    <thierry> 6 probllematic tests:

    <thierry> The old 1.0 static founctionalities are the one that could
    raise issues. We are OK with the 2.0 tests

    <thierry> Lofton: Can you send more info when you have more results
    ?

    <Chris> SVG has some animated miterlimit tests

    <Chris> animate-elem-35-t

    <Chris>
    file://localhost/E:/cygwin/home/Chris/W3C/WWW/Graphics/SVG/Group/rep
    ository/testsuite/1.1/htmlObjectHarness/full-animate-elem-35-t.html

    <thierry> Probably by tomorrow.

    <thierry> Ulrich: Will send the result tomorow:

    <thierry> Lofton: For the schedule we are thinking about a 30 day CR
    phase beginning sept 5th, ending Oct 5th

    <thierry> Lofton: Any adjustement we need to do in this time frame

    <thierry> Lofton we are already covered on the 2.0 tests

    <thierry> Dave: we have a problem on the following funct -
    InterpollatedInterior

    <thierry> Ulrich: We do not support this funct yet

    <thierry> Dave : It does work in our 1.0 implementation.

    <Chris> Larson 2.0 viewer uses OpenGL for rendering

    <thierry> Don: But not as good in our 2.0 viewer

    <thierry> Ulrich will send an Implementation to Chris and Lofton
    tomorrow

    <thierry> Ulrich has now left the telecon.

CR exit criteria review

    <thierry>

    4.html

      [32] 
http://lists.w3.org/Archives/Public/public-webcgm-wg/2006Jul/0084.html

    <thierry> Lofton: we could change the profile, losen for 1.0
    functionalities that are issues

    <thierry> Chris: We can mention in the CR draft that these funct are
    at risk.

    <thierry> Don: We are going to stuff we have resolved a long time
    ago

    <thierry> Don: The DOM is THE objective

    <thierry> Don: Each vendor want to have a good static capabilities,
    but vendors really want to focus on a DOM

    <thierry> Chris: You can say it is required, if it is not correctly
    implemented

    <thierry> Lofton: We are not going to remove a 1.0 implementation
    because we do not have two perfert implementation

    <thierry> Chris: it is better to say in the Profile that it is
    optional than to have diffrent rendering in different viewers

    <thierry> Chris: we could have also some authoring guidelines

    <thierry> Benoit: Would be happy with relaxing the profile

    <thierry> Don: We could implement the Minorlimit

    <thierry> Don: we are 2 implementations; one for static and a new
    one handling Dynamic

    <thierry> Don: the real interoperability should be the DOM

    <thierry> Benoit: If chris says the only way is to change the
    profile, I am fine with that

    <thierry> Chris: W3C should probably have a sort of QA phase were we
    could use much more tests to test implementations

    <thierry> Chris: These would not be substantive changes, needing
    another Last Call

    <thierry> Lofton: to pass the patern tests we should have the size
    optional ?

    <thierry> Don: The gradient in the Interpolated Interior is the
    issue we have

    <thierry> Lofton: Need to be clear on which tests we have problems
    with

    <thierry> Lofton: Either two passes on each tests or downgrade the
    feature

    <thierry> Lofton: the feature at risk wil be the Interpolated
    Interior

    <thierry> Benoit: The miter limit we could have that done in our
    implementation.

    <thierry> Benoit: If we have time we should look at the impact on
    the profile

    <thierry> Benoit: I was thinking about miter limit, to to say so in
    the profile

    <thierry> Benoit: there is also an internal issue raised by Ulrich
    (Benoit will repport about that)

    <thierry> esolution: the candidate feature at risk are the pattern
    size aspect of deniable patterns and the performance requirements
    for miter limit

    <thierry> Resolution: the candidate feature at risk are the pattern
    size aspect of deniable patterns and the performance requirements
    for miter limit

    <thierry> Lofton: the feature Interpolated Interior is covered by
    the Larson 1.0 Implementation, so we are OK with this one

    <thierry> Benoit: we are pretty good on Unicode

    <thierry> Lofton: In the Test suite, there are 7 tests that are
    Chinese and Japanese, where two are IRI tests using Unicode
    caracters

    <thierry> Dieter : Pattern size - It is cearly a bug. We will fix
    it.

    <thierry> Dieter: miter limit: We think we pass this test.

    <thierry> Chris: It depends if you are implementing a converter or a
    viewer

    <thierry> Dieter: It is only a screen issue but it is correctly
    printed on a PS printer

    <thierry> Dieter: actually a screen performance issue.

    <thierry> Dieter is fine with the DOM change about highlight
    resolution discussed this morning

    <thierry> Benoit: we would be inrested in a flash object method

    <thierry> Lofton: that would be for 2.1 ...

    <thierry> Lofton: we have preliminary features for 2.1 and 3.0

    <thierry> Dieter: I would like to make sure this can be added latter
    on

    <thierry> Lofton: At this point I would like to have the minimum
    changes, this is the case for the highlight methodFlashing

    <thierry> Don: I would also like to wait before adding it. It may be
    tight to other features

    <thierry> Dieter: We could replace true/flase with flash On/off in
    the clear hightlight method

    <thierry> CHris: instead or True/false we could use a numeric value,
    allowing to add another value latter on, not a bolean value.

    <thierry> Dieter: Yes that is a good suggestion

    <thierry> Lofton: Sounds fine with me.

    <thierry> Resolution: second parameter is called behavior, and the
    value is add

(continue) CR process discussions

    <thierry> Lofton: will exit CR on 5th October

    <thierry> Lofton: This should allow to more to PR by end of October

    <thierry> Thierry: yes before Ac meeting in November. it would be
    usefull to advertize during the AC meeting wehere all AC Reps are
    present

    publication date on sept 05. Ending CR date on oct 5th

    <thierry> Thierry : SOTD includes the exit criteria adopted by the
    WG and 3 features at risk

    <thierry> features at risk are : Pattern size aspect of definable
    patterns, Performance requirements for Miter limit., Text on a path

    <thierry> The cover page also fulfills the pubrules

    <thierry> Thierry: Lofton needs to copy and paste it into the CR
    draft
