An excellent piece from Businessweek describes the due diligence process undergone by Disney chief Bob Iger, which is just one of many good bits of the piece. It reveals a bit of Lucasfilm trivia I didn't know about, the Holocron:

His company maintained a database called the Holocron, named after a crystal cube powered by the Force. The real-world Holocron lists 17,000 characters in the Star Wars universe inhabiting several thousand planets over a span of more than 20,000 years. It was quite a bit for Disney to process. So Lucas also provided the company with a guide, Pablo Hidalgo. A founding member of the Star Wars Fan Boy Association, Hidalgo is now a “brand communication manager” at Lucasfilm. “The Holocron can be a little overwhelming,” says Hidalgo, who obsesses over canonical matters such as the correct spelling of Wookiee and the definitive list of individuals who met with Yoda while he was hiding in the swamps of Dagobah.
