Minutes of TT WG Teleconference on 03/31/05 Attendees Glenn Adams (XFSI, Chair, Scribe) [GA] Mike Dolan (invited expert) [MD] Geoff Freed (WGBH/NCAM) [GF] Sean Hayes (Microsoft) [SH] Erik Hodge (RealNetworks) [EH] Thierry Michel (W3C) [TM] Regrets David Kirby (BBC) [DK] Dave Singer (Apple) [DS] ************************************************************************ 1. Request for Delayed LC Comments from MMI/SYMM WGs ************************************************************************ [GA] Asks if any objection to approving delay until 04/25 of LC comments from MMI and SYMM WGs. [*] No Objection. Action: [GA] to inform MMI and SYMM WGs that we will accept comments until 04/25. ************************************************************************ 2. LC Comments ************************************************************************ [GA] Notes a few interesting comments received so far: 1. Potential need for <img/> support; [GA] thinks one way to accommodate while maintaining no external references would be something like: <img type="image/png"> <data encoding="hexBinary">...04ff69....</data> </img> This is preferred over use of "data:" URI scheme due to typical limits on length of attribute values. 2. Potential need for <font/> support or for specifying minimum glyph set support by built-in font families. 3. Further input on need for real-time or media-time durations in combination with event based marker timing. Action: [MD] to review new equipment in DFXP LC for SMPTE timing mode. ************************************************************************ 3. Upcoming Meeting Schedule ************************************************************************ No telecon on 04/07 due to [GA] travel. Next meeting will be F2F at Apple. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ START SUMMARY ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ *** RESOLUTIONS *** *** NEW ACTION ITEMS *** Action: [GA] to inform MMI and SYMM WGs that we will accept comments until 04/25. Action: [MD] to review new equipment in DFXP LC for SMPTE timing mode. *** CURRENT ACTION ITEMS *** Action: [SH] To elaborate use cases for audio embed usage. Action: [GA] to generalize and clearly articulate [MD] feedback on XBC with TT-AF structured timing as use case, then send to WG for review prior to forwarding to XBC. Action: [GA] change language in vocab element defs that defines equiv class of attrs in foreign namespace to not admit unqualified attrs. Action: [GA] need to ensure that we document whether time intervals are half-opened intervals or closed. We always use half-opened intervals for [begin,end) = [begin,begin+dur). Action: [GA] ensure there is language that gives precendence to end over dur in case both are specified. Action: [GA] formulate proposal to express coordinates in rows and columns and to express total # of rows/cols for which content was composed. Partially done. Needs more work. Action: [GA] ensure that all elements can also take ttm:* attributes, but need to define in context of specific elements which ones have standard semantics. Action: [GA] define semantics of ttm:agent metadata attribute such that inner specifications override outer specifications, e.g., Action: [GA] for each AFXP style property that we don't include in DFXP, need to specify a normative default value for DFXP, but do so in a way that doesn't require normative use of AFXP specification. Action: [GA] since <color>s are opaque, need to say so in verbiage. Action: [GA] Ensure that if we define overflow="clip" on region that we say that outermost region is expected to be clipped in all cases. Action: [KB] Review the March 2002 TT Task Force requirements to see if the current TT-AF-1-0-REQ does not include all those earlier requirements, and if not, then make a case for including in TT-AF-1-0-REQ. [TM] will help as required and report back to WG. Action: [GA] To verify that TTPRO DB is well configured to handle DFXP comments. Action: [DK] To help verify that TTPRO DB is populated with open DFXP issues. Action: [SH] to submit message to reflector on text-outline issue; Action: [KB] to review metadata for content adaptation workshop presentations [15] to see if there is relevant input to our work on DFXP. Action: [GA] add language under namespace and/or conventions section that indicates that if an element type is used unqualified in spec then it is in tt: namespace. Action: [GA] further research required on quoted-string. Action: [DK]|[GF] respond to query at [2]. Action: [GA] put issue raised by John Birch regarding use of durations with discontinuous marker mode onto F2F agenda. Action: [GA] put issue raised by John Birch regarding use of background style variations onto F2F agenda. Action: [TM] Contact Adam Wells <adamw@apple.com <mailto:adamw@apple.com?Subject=Re:%20Draft%20Minutes%20-%20Telecon%2003%2F31%2F04&In-Reply-To=%3C7249D02C4D2DFD4D80F2E040E8CAF37C06C6C6@longxuyen.xfsi.com%3E&References=%3C7249D02C4D2DFD4D80F2E040E8CAF37C06C6C6@longxuyen.xfsi.com%3E>> the week before F2F to indicate number of attendees. Action: [*] Reminder to register for F2F. *** OPEN ISSUES *** See Issue DB. *** Upcoming Meetings *** NO telecon on 04/07. F2F - Apr 11-13/2005 - Mt View, CA (Apple) *** URIs *** ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ END SUMMARY ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
