Interoperability Working Group Charter Has Expired
The IDE Working Group was chartered from 2007 through 2010, published:
as official OpenAjax Alliance Specifications, helped produce various white paper, coordinated with OpenSocial Foundation on integrating OpenAjax Hub 2.0 into OpenSocial Gadgets 1.1, worked on various other initiatives (e.g., OpenAjax Registry) and the charter expired at the end of 2010.
Interoperability WG Rechartering Approved
OAH 2.0.1 open source update posted
The 2.0.1 release of the open source reference implementation for OpenAjax Hub 2.0 contains the following updates:
- No more clicking sounds on IE6/IE7. With Hub 2.0.1, we borrowed a coding trick from OpenSocial Gadgets to pass messages across frames in IE6/IE7 that avoids the clicking sounds that occurred with the 2.0 open source.
- Refactoring and consolidation. The Hub 2.0.1 code was refactored in a significant manner, with the result that the code is smaller and cleaner. This refactoring is also a major step in the direction of allowing OAHub to be integrated into OpenSocial Gadgets for inter-gadget pubsub.
OpenSocial/OpenAjax Integration Underway
OpenAjax Alliance is collaborating with the OpenSocial Foundation and the Apache Shindig project to merge the pubsub features from OpenAjax specs (mainly, OpenAjax Hub 2.0 Specification, but also a couple of features out of OpenAjax Metadata 1.0 Specification. Here are some pages that show work-in-progress:
Hub 2.0 Spec Approved
The Interoperability Working Group has approved the OpenAjax Hub 2.0 Specification.
White Papers Available
The Interoperability Working Group has written several white papers about the OpenAjax Hub 2.0. These white papers are available at the following URLs:
OpenAjax Hub 2.0 Reference Implementation Enhancements
We are working on some updates to the OpenAjax Hub 2.0 reference implementation within the OpenAjax project at SourceForge. These updates will probably be completed in late 2009. Here are some things happening with this source code update:
- Addition of a new cross-frame transport layer for IE6 and IE8 to eliminate the clicking sound with message passing when widgets are placed into Iframes
- Reorganization, cleanup, and improvement of the transport code
- Make progress on the OAHub 2.0 code to allow future sharing of cross-frame transport logic between a future version of Apache Shindig with a future version of OAHub 2.0 reference implementation
Howard has proposed a recommended event envelope object: Simple Event Envelope
Interoperability Working Group (v2) Approved

Interoperability Working Group (v1) Approved
The OpenAjax Alliance Steering Committee approved the creation of a formally chartered Interoperability Working Group on May 14, 2007. The approved charter can be found at http://www.openajax.org/member/wiki/Interoperability_Charter.
OpenAjax Hub 1.0 Approved
The members of OpenAjax Alliance and its Steering Committee approved the release of OpenAjax Hub 1.0 per our Development Process at http://www.openajax.org/process/DevelopmentProcess.pdf). The approved Hub 1.0 specification is at:

It is relevant to this discussion because it talks about features and issues within the OpenAjax hub.

- (Historical) Image:Tibco-Dojo-Event-Hub-Proposal-2006-06-19.pdf - Tibco and Dojo have submitted a proposal for discussion and consideration that outlines an Open Ajax Event Hub (OAH) that provides standard methods for gracefully managing multiple toolkits in context of each other: a simple approach to toolkit interoperability.
- Alternate Hub Proposal Using XML Namespaces - Here is a proposal that attempts to provide the same functionality as the Tibco/Dojo proposal but expresses the markup in a manner that attempts to channel the spirit of W3C's architecture vision and thereby leverages XML namespaces. Not sure if this is a good idea or not, but here it is for people to review.
A related technology effort is the XAP proposal that is now an incubator projects at apache.org. Here is a wiki page that provides an executive summary of XAP and includes links to detailed information on XAP:
James Margaris of Nexaweb pointed out that we need to have a clear definition of what we are trying to accomplish. Here are notes, which are mostly directed at the issue of markup mixing:
