In March of 2012 I presented The Alice in Wonderland World of Fields and Entities at DrupalCon Denver.
Drupal 7 is a topsy turvy place where everything you thought you knew about content types and fields goes out the window. Enter the Mad Hatter's world where anything can be an entity and fields can go everywhere. Already the floodgates are opening as developers and users find new ways to take advantage of all the possibilities: Field Collection, Entity Reference, and Entity Construction Kit are brand new concepts. Bean has re-invented blocks as entities. Media has re-invented files as entities. Organic Groups has been re-written to make groups entities. Drupal Commerce makes commerce transactions into entities. The new Entity Translation module treats groups of translated fields as entities. And D7 is just getting out of the gate. This session looks at some of the new entity and field modules, and some older modules that have been re-invented for D7. We'll talk about how they work and where they could be useful and what they get from using the new entity framework.
