All the source code of the SPINE project, is managed through some subversion repositories (where subversion is a version control system that is a compelling replacement for CVS in the open source community).

Read-only access to these repositories is granted to the SPINE user community under the terms of the LGPL license, where not explicitly differently indicated. In order to reduce possible annoying disturbing effects of web-robots access, a special account has been setup to access these repositories, where both username and password are the name (5 letters in lowercase) of our framework or "backbone".

The repository trees can be browsed via a simple Web browser or, alternatively, you can prefer using a subversion client, e.g. tortoise, that enables you to view the complete histories of any file in the repository.

The SPINE subversion repository contains all the SPINE code (both the Node side and the Server Side) and documentation.
