What is the Holocron?
In the fictional Star Wars universe, a Holocron is a device (usually cube-shaped) that serves as a repository of Jedi knowledge. The Holocron was first introduced in the Dark Empire comics. For the Attack of the Clones Visual Dictionary, Holocron "props" were built of a Jedi Holocron, a dodecahedron-shaped Great Holocron, and a pyramid-shaped Sith Holocron.

In the real world, the Holocron is an internal database maintained by Lucas Licensing that tracks all the fictional elements created for the Star Wars universe. The database includes material from the films as well as everything from the Expanded Universe (EU) which includes books, comics, videogames, trading cards, roleplaying games, websites, toys, cartoons, and just about every officially sanctioned fictional element of the Star Wars universe.

What are the main types of entries in the Holocron?
The Holocron classification system is loosely based on the one used in the Behind the Magic CD-ROM:
Character
Location
Alien/Creature
Technology (Droids, Vehicles, Weapons)
Group/Organization
Terminology
Event
Flora
Language

Is there any way to put on an online version that people could browse over for fun?
There are no current plans to make the Holocron available to the public either in an online or published version. In addition to being an archive for information that has already been published, the Holocron is a tool to track everything that is currently in development. Information is entered at the earliest stages, so there is information about products that won't be released until years later. It is also used to store unpublished reference information.

Are the entries in the Holocron sorted as canonical & non-canonical? Are there various degrees of "officialness"?
The database does indeed have a canon field for each individual entry and for sources, though the canon level of the entry would overide the canon level of the source since it factors in other sources associated with that entry. When determining canon levels for individual entries, anything in the films and from George Lucas (including unpublished internal notes that we might receive from him or from the film production department) is considered "G" canon. A new level we recently added is "T" canon, comprising of the theatrical release of The Clone Wars and the television series, in addition to the planned live-action television series. Next we have what we call continuity "C" canon which is pretty much everything else from the EU. There is a secondary "S" continuity classification used for older published materials created when there was less attention to making everything in the EU fit with everything else in the EU. But, if it is referenced in something else it becomes "C". Similarly, any "C" canon entry that makes it into the films can become "G" canon. Lastly there is non-continuity "N" which we rarely use except in the case of a blatant contradiction. Any contradictions that arise are dealt with on a case-by-case basis.

Is there an Indiana Jones version of the Holocron?
Yes. We call it the Indycron.

Here's an article on Wizards.com from a few years ago that gives some additional insight into my role as Keeper of the Holocron.
