OpenSocial 1.1 release with OpenAjax Hub inside

Blogged by: Jon Ferraiolo on November 20, 2010 at 5:49 pm

After more than a year’s worth of collaboration between OpenSocial Foundation and various members of OpenAjax Alliance, yesterday OpenSocial Foundation announced the release of the OpenSocial 1.1 specification. One of the major new features in version 1.1 of OpenSocial Gadgets is the inclusion of OpenAjax Hub as the mechanism for inter-gadget communication.

The announcement talks about the use of OpenAjax Hub:

Version 1.1 officially support an inter-gadget eventing system based upon the OpenAjax Hub. “The OpenAjax Hub is a set of standard JavaScript functionality defined by the OpenAjax Alliance that addresses key interoperability and security issues that arise when multiple Ajax libraries and/or components are used within the same web page.” By incorporating this technology into OpenSocial, gadgets are now able to declare, as part of the module definition, events to which they are able to publish and subscribe. In addition, this specification has reserved several topic namespaces for use by OpenSocial. Please refer to the Inter-Gadget Eventing in the Core-Gadget specification for more information.

OpenAjax Hub is included in the Gadgets spec mostly via reference to the OpenAjax Hub 2.0 Specification. The Apache Shindig open source implementation (version 2.0.x) includes the OAHub source code within its distribution.

Congratulations to everyone! It isn’t often that major parts of the industry get on the same technology page.
