I attended DBPL 2013 in Riva Del Garda, Italy - a very attractive venue. I was stupid and only came for the day of the workshop. There were a lot of interesting talks.

- Stephanie Scherzinger spoke on work with Meike Klettke and Uta Störl on schema evolution for NoSQL data.

- Soren Lassen (Facebook) gave an invited talk about Facebook's graph search (the Unicorn engine)
- Radu Ciucanu spoke about work with Slawek Staworko on inference of unordered XML schemas from data.
