I repost some of my blog posts made @ liip. Please see here for the original post and comments: http://blog.liip.ch/archive/2011/04/12/news-for-the-symfony2-cmf-second-phpcr-implementation-hackday-announcement-and-phpcr-to-become-official.html
The Midgard Project started to implement the PHPCR interfaces for their content repository. From their website: Midgard is a persistent storage framework built for the replicated world. It enables developers build applications that have their data in sync between the desktop, mobile devices and web services. It also allows for easy sharing of data between users.
This prompted us to clean up the separation between phpcr and jackalope. You find now everything that is phpcr in general on https://github.com/phpcr/ , while the jackalope implementation stays at https://github.com/jackalope/ . There will be some changes inside the code to separate stuff. Luckily we planned to separate all along, but with only one implemenation around, unfortunately we where sloppy in some places.
To boost the phpcr implementations, Liip will invite to a phpcr hackday to work on jackalope, the midgard layer and the api tests. For now, there is a doodle up to decide on the details. Fill it in if you are interested.
If you are more interested in the upper layers of the cmf system, there will be a Symfony CMF camp in italy end of july, organized by ideato.
And finally, we submitted PHPCR to the JCR group with the idea of having PHPCR officially sanctioned as the PHP interface for the next version of the content repository standard.
