(The most current version of the OpenAjax Hub Specification is at http://www.openajax.org/member/wiki/OpenAjax_Hub_Specification.

(This wiki page holds a portion of the version 0.5 internal editorial draft for the OpenAjax Hub 1.0 Specification. The home wiki page for the version 0.5 draft specification is at http://www.openajax.org/member/wiki/OpenAjax_Hub_Specification_v05. Version 0.5 is preserved for historical reasons and therefore may be out of date. A key point about version 0.5 is that it holds the first stable version after implementing decisions about the Hub made at the March 2007 face-to-face meeting and in the follow-in meetings which resolved detailed issues from March to May 2007.)
