We just came back from FroSCon, a large, international open source conference near Bonn, Germany. Jan Steemann, one of the core developers of ArangoDB, had a talk on modelling data in a schema-free world. Jan was given the largest room in the conference for this talk, fortunately a lot of people showed up and even stayed ;-).
You can find Jan’s presentation below.
Note: Jan will give this presentation again in September at the nosql user group Cologne. We’ll probably record it, if you can’t come but would like to be notified when the recording is available, contact me at dorthe at arangodb.org.
