Better late than never

New OSGi specifications released - Compendium 4.3 and Residential 3.4

After some delays, the OSGi Alliance have made the latest specification documents available for download, in Compendium 4.3 and Residential 3.4 - the latter being the first of its kind.

The Compendium 4.3 document incorporates the latest specifications from the OSGi Enterprise 4.2 release, including Remote Services Admin, JTA, JDBC, JNDI, persistence framework JPA, Web Applications and SCA Configuration. Also making its way into the Compendium is the new Coordinator specification, which makes it possible for multiple parties to collaborate on a common task without a priori knowledge of who will collaborate in that task, which is a useful addition for OSGi.

The specification states:

A collaborator can participate by adding a Participant to the Coordination. The Coordination will notify the Participants when the coordination is ended or when it is failed.

Enhancements have been made to existing specifications, notably the Configuration Admin has been updated to allow multiple bundles to access the same configuration and extend the security model to allow configuration "regions". Event Admin and Declarative Services have both undergone transformations too.

The Residential Version is a new initiative from the OSGi Alliance, brought in to lend a helping hand to those within the Residential market, so areas such as consumer electronics. The document lays out the foundations for this market by providing requirements and protocols for management of residential environments.

BJ Hargrave wrote in the announcement:

Requirements and management protocols for this environment are defined in the specifications by consortias like the Home Gateway Initiative (HGI), the Broadband Forum (BBF) and the UPnP Forum. 

Check out the official announcement for further details about these latest documents. You can download the specification PDFs, companion code JARs and javadoc from the OSGi website as well.

It's a good first step since Peter Kriens left the foundation, and as expected, the work continues without him.
