Agenda Details

record keeping note: we recently introduced tracker products for the themes established at the June meeting in Cambridge: web applications, metadata, html 5 review.

1. Convene, review agenda
   • scribes: Jonathan volunteered for the 1st morning (8 Dec).
     Henry volunteered for the 2nd morning.
     Note we'll fill the remaining slots before taking the morning break.
   • Roll call
   • Goal: establish success critera for work on Web Application Architecture
     • form of the work?

     • TOC/outline (required reading)
   • Goal: clarify our interest in metadata
   • ACTION-330 on Dan Connolly: Prepare Dec f2f agenda in collaboration with Noah etc. - pending review
     • Suggestion: collaborative agenda management using Zakim's agenda tracking:
       1. Dan seeds the list for the day from the agenda prepared by the chair
       2. Participants use "agenda + ..." to make agenda requests; e.g.
          • refinements of broad topics
          • things you want to get back to in this session (i.e. before a break)
          • things you want to get back to today
          • things you want to get back to before the meeting ends
       3. At his earliest convenience, e.g. during a break, the chair should consider prioritizing agenda requests by reordering the agenda. Participants may reorder the agenda in consultation with the chair.
       4. At the end of the day, items are either promoted to the summary above for use the next day or dropped.
