== Links == Chat Log: http://www.ietf.org/jabber/logs/vwrap/2010-03-23.txt Audio: http://limestone.uoregon.edu/ftp/pub/videolab/media/ietf77/ietf77-ch8-tue-am.mp3 == Meeting Setup == We attempted to bridge the real life (RL) meeting room, the XMPP (Jabber) room, and Second Life for what we call a "Mixed Reality" meeting. The setup was as follows: * MacBook Pro doing A/V encoding and streaming (via third party provider under contract) * Audio/Video capture via an HD camera. (ISSUE: Unfortunately the mic wasn’t amplified and we didn’t have the right cables to plug into the room’s mic setup. Also, the stream had a 10s delay.) * Audio stream from the room mics (provided by the IETF). This was high quality but maxed out due to the number of remote users. * Jabber chat was relayed to/from SL chat. The real-world projector was showing SL so both chats appeared. * Virtual world slide projector, shown on the real world (so both realities saw the same content). (ISSUE: didn't have access permissions set up on the in-world controls, so attendees accidentally advanced the slides a few times; ISSUE: since we were looking at the slides, we couldn't see the in-world audience; ISSUE: audio delay meant that slides advanced too early) This was an interesting experience, since at the IETF meetings the Jabber rooms, while respected, are not considered first-class attendance and remote participants are responsible for adapting with little concession from the physical event. SL attendees, however, are used to being considered full participants. David W. Levine counted 25 RL attendees, 24 SL avatars (not counting "duplicates" also present in RL), and 9 attendees in Jabber (ditto) == Opening (chairs) == http://www.ietf.org/proceedings/10mar/slides/vwrap-9.pdf We started just a couple of minutes late (waiting for folks to wander in, jabber.org auth to work, and computer swappage). Barry started off the session with an apropos song. == Topic #1: Open Issues in Abstract Type System and Foundation (Mark Lentczner) == http://www.ietf.org/proceedings/10mar/slides/vwrap-0.pdf As this addressed the two largest standards-track drafts in the WG, it was the "meat" of the session, and took up the first hour. Mark summarized his session here, including the open issues that were discussed and consensus reached: http://www.ietf.org/mail-archive/web/ogpx/current/msg00909.html And a summary of LLSD implementations is given here: http://www.ietf.org/mail-archive/web/ogpx/current/msg00910.html == Topic #2: Intro and Goals (Meadhbh Hamrick) == http://www.ietf.org/proceedings/10mar/slides/vwrap-1.pdf The big open question was whether or not the Intro and Goals I-D should be finalized sooner (with elements almost certain to change) rather than later (after elements are more broadly/fully understood locked down). The consensus that we should not delay finalizing this (i.e. submitting as an information RFC); known issues should be addressed, but extensions such as an enumeration of deployment patterns can be included in replacement RFCs. == Topic #3: Client-Side Capabilities (David Levine) == http://www.ietf.org/proceedings/10mar/slides/vwrap-2.pdf Not a lot of discussion here since there aren't multiple implementations yet. Some good clarifying questions by the floor. == Topic #4: User Authentication (Meadhbh Hamrick) == http://www.ietf.org/proceedings/10mar/slides/vwrap-3.pdf Heated discussion initiated in-world about issues raised on the mailing list (specifically, account id vs. multi-part SL-style names) that had not been addressed in the draft. There was some confusion because those in the physical room believed the drafts had been updated, while those attending remotely (and thus accessing the documents) were able to confirm they had not. The chairs called on participants to propose specific changes to the drafts rather than general complaints. We also noted that: IETF has SVN for documents; we could put the XML of the I-Ds in public SVN so diffs can be proposed IETF has trac for issue tracking; we can take reported issues and proposed changes and formally track them. The chairs and draft authors/editors will discuss use of SVN and trac for drafts. == Topic #5: Cable Beach and VWRAP (John Hurliman) == http://www.ietf.org/proceedings/10mar/slides/vwrap-3.pdf A summary of Intel's experience building Cable Beach to learn about asset and inventory storage for virtual worlds, implementation experience with VWRAP elements like LLSD, and outline of the future direction of the work: "The Cable Beach research project is now entirely folded into VWRAP development efforts" == Topic #6: Client Application Launch Message (Meadhbh Hamrick) == http://www.ietf.org/proceedings/10mar/slides/vwrap-4.pdf We skipped this topic since we were running short on time. == Topic #7: Deployment and Trust Patterns (David Levine) == http://www.ietf.org/proceedings/10mar/slides/vwrap-5.pdf (David wins the "use of clip art" award for this presentation.) == Topic #8: What’s NOT in VWRAP (Joshua Bell) == http://www.ietf.org/proceedings/10mar/slides/vwrap-6.pdf We skipped this topic since we were running short on time and it was a co-chair's session rather than a "guest speaker". [Note: Joshua presented the content to the SL "AW Groupies" group a few weeks later.] == Topic #9: Virtual World Accessibility (Katherine Mancuso) == Presentation on universal access, and why the IETF needs to care at the protocol level - i.e. don’t require heavyweight clients, don’t couple visual presentation unnecessarily, and so forth. == Closing (chairs) == There was not time to call for consensus for the WG to adopt the I-Ds; indicated discussion should occur on the list.
