I am still thinking that it would be better to have a PHPCR-ODM edition. But then I guess that opens the lid of the "edition for everything" box.

However it is the foundation of any tutorials we have at the moment.  But I guess that could change when we start supporting ORM  This tutorial for example could easily be realized in the ORM without losing any functionality when we add ORM support for menu and routing auto.

Maybe an article, "Getting started with PHPCR-ODM" which demonstrates the various options you have (jackalope, doctrine-dbal, mongodb) the merits of each and concise instructions on how to implement them from the SF SE.
