Serious technical discussion about Linden Lab's Architecture Working Group (AWG). "AW Groupies" is an unofficial, Resident-operated group, though most (all?) members also participate in the AWG.

Invite only (apply in-world to Zha Ewry), but the criterion is simple. Show up and contribute to the AWG, at Zero Linden's office hours, or on the Wiki, or on SL-Dev or in the irc channel for the Python test client.


The main AWG meeting is held annually or semi-annually. We now meet up to 8 times a week in-world, counting AW Groupies meeting, Zero's office hours, Which's office hours, Enus's office hours, Whump's office hours and the pygop daily meetings.

Our main focus these days is on the Open Grid Protocol, the Open_Grid_Public_Beta and the pyogp Python test harness for protocol testing.

Also members are quite active on the wiki and in the SLDEV mailing list.

A public SVN repository is open to all AW Groupies members here:

Contact anyone with root on for an account if you are in the AW Groupies group in-world.

Architecture Working Group meetings

In-World Meetings

Chat Logs

Chat logs of the in-world meetings are published and accessible via the links below:

  • 2007 meetings
  • 2008 meetings
  • 2009 meetings

(if you post chat logs, you might want to use the sllog2wiki perl script to turn them into a more readable wiki table format ready to copy & paste into the chat log page)

Chat logs of AWGroupies meetings should be summarized on the wiki.

Viewpoint Advocacy Groups

Viewpoint Advocacy Groups - groups to focus on specific requirements.

AWG-specific VAGs

AWG-related VAGs


Work-in-progress wiki pages are architecture pages that are (as the name implies ;-)) work in progress. Once the group has reached consensus that a particular topic is "good-to-go" we'll graduate that page to the main AWG page.
