The Holocron is a database and catalogue of the Star Wars expanded universe created by the publishing department of Lucas Licensing in January 2000. It is curated by Leland Chee, whose formal job title is Continuity database administrator, but who is known as Keeper of the Holocron by Star Wars fans; Chee describes it as a "dream job". The Holocron contains details and designs about the characters, creatures, languages, locations (planetary systems, planets, moons, cities and towns), vehicles, and weapons found in the fictional universe of Star Wars. Before creation of the Holocron, story synopses and glossary details about Star Wars were maintained in black binders referred to as "bibles".
The Holocron is used to establish continuity and prevent a reboot of the Star Wars universe, ensuring the integrity of "a singular continuity across all forms of media" using retroactive continuity to resolve discrepancies when necessary. New products are vetted against the Holocron and must be consistent with its contents or expand upon the Star Wars canon it contains. This includes all films, animated series, novels, comic books, manga, computer and video games, and merchandise such as toys and trading cards. Chee has said "In the end, my ongoing vision is that as long as there's the Holocron, Star Wars will not reboot".
The FileMaker database is named for an object within the Star Wars universe, a crystal "holographic chronicle" cube powered by the Force that is used as a repository of mystical Jedi knowledge.
Entries in the Holocron are assigned a code based on their level of canonicity. The highest level is "G-canon" or "GWL", the content of which represents the words of Star Wars creator George Lucas and comprising the six films. The "T-canon" level, standing for "television canon", represents the 2008 movie and TV series The Clone Wars. The "C-canon" level is the continuity canon that includes the expanded universe and is canonical unless superseded by G- or T-canon. The two lowest levels are "S-canon," secondary canon related to older novels and texts (and the poorly received Star Wars Holiday Special), and "N-canon", which consists of details either not considered part of the Star Wars canon (such as crossovers with unrelated continuities) or removed from it, for example alternate endings to video games.
In 2012, the Holocron was transferred to Lucasfilm's marketing division. It had by this time accumulated information beyond the scope of the Star Wars universe and incorporated "style guides, timelines, spelling dictionaries, fonts, banks of trivia and quotes, and galaxy maps".

The Star Wars movies need to be reinvigorated, but not reinvented. Lucas himself has already sketched out the creative map for the films. He certainly has enough material: he maintains a database called the Holocron that contains a staggering 17,000 Star Wars characters who "live" on several thousand different planets.
