It’s a mere two weeks til the Freebase Hack Day and Unconference on July 11th in San Francisco. If you haven’t yet signed up, you should!

Plans are coming together. We’re starting to organise some projects to hack on and hunt down people to run sessions in the unconference. If you’ve got a project or a subject area you’d like covered, let us know! So far, some of the exciting topics that will be part of Hack Day include:

• We’ll be launching Acre 1.0 just a few days before Hack Day. Jason Douglas will be showing off the features of our hosted app development platform, including the ability to share and clone apps, connect to other APIs with our keystore and OAuth, and build queries and templated web pages based on Freebase data more easily than ever before. Acre’s come a long way since our last Hack Day, so don’t miss this. (Read more about Acre.)
• The MQL Boot Camp will be run this year by Bryan Culbertson. Learn how to query against Freebase’s structured data about almost 6 million topics, and see the new features of our query editor, including tab-completion for syntax and schema. (Read more about MQL and the query editor).
• Learn how to use Freebase to enhance your website with structured data, like the Wall Street Journal, or build entire apps and websites on Acre, like Tippify.
• Hack on apps like our Games With A Purpose, a TV program schedule mashup, and more. If you have a project and you’re looking for partners, technical help, or ideas, bring it with you! We’re also working on having a handful of projects ready for people to hack on who haven’t brought one of their own.)
• Find out about how Freebase’s part in the Linked Open Data world, and how to use Semantic Web techniques and tools to work with Freebase data.

Same as last time, we’ll have three meeting rooms available for presentations, discussions, and other unconference programming, while our main lunch room area and lounge will be available for general hacking and chat. Come prepared to talk about what interests you, share your ideas, and collaborate!

This event is completely free, but places are limited.

Coffee, lunch, and snacks will be provided, including vegetarian options. Unfortunately we can’t offer childcare or kids’ activities at this time, but parents of babies are welcome to bring them.

Please help us spread the word. Link to this blog post, or to http://freebasehackday.eventbrite.com/, tweet about the event, or just tell your friends and colleagues. It’s going to be a great event!
