It is also used as a backing store for the web view of the registry at https://www.khronos.org/registry/sles/ ; commits to the master branch of this repository will be reflected there.

In the past, the OpenSL ES registry was maintained in a public Subversion repository. The history in that repository has not been imported to github, but it is still available at https://cvs.khronos.org/svn/repos/registry/trunk/public/sles/ .

Interesting files in this repository include:

index.php - toplevel index page for the web view. This relies on PHP include files found elsewhere on www.khronos.org and so is not very useful in isolation.
api/ - OpenSL ES header files
specs/ - OpenSL ES specification documents.

Adding Extension Specifications

At present there are no extensions defined for OpenSL ES, and no process for extending it.
