FLOW3, Symfony CMF, JCR, Doctrine and CouchDB
Among the attendees were not only Symfony developers but also Benjamin Eberlei (Doctrine Project), Nils Nadermann (phpBB), David Nuescheler (Day Software) and a lone FLOW3 developer - me.
On the first day David Nuescheler (the JCR specification lead) gave an introduction to JCR and talked about the plans for JSR-333 (the next version of the specification). Since the basics were known to me, I was more curious about what will be the scope of JSR-333.
