I'm developing a PHP application that connects to an Alfresco instance for application content storage. Never having used Alfresco before, I'm looking for some good tutorials that explain the structure and organization of an Alfresco repository, i.e. how Nodes work, etc.
I haven't found much beyond the Alfresco Docs on the alfresco.com website, and while they do a good job explaining how to setup and configure an alfresco solution, they don't seem to talk as much about how the content repository is structured. A google search doesn't reveal much in the way of free online tutorials for Alfresco development.
Anyone know any good free tutorials for this, or will I have to end up finding a book written on the subject?
