Oh Boy! Another Canon Debate!
Are the entries in the Holocron sorted as cannonical & non-cannonical? Are there various degress of oficialness?
The database does indeed have a canon field. Anything in the films and from George Lucas (including unpublished internal notes that we might receive from him or from the film production department) is considered "G" canon. Next we have what we call continuity "C" canon which is pretty much everything else. There is secondary "S" continuity canon which we use for some older published materials and things that may or may not fit just right. But, if it is referenced in something else it becomes "C". Similarly, any "C" canon item 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 or for things that have been cut.
I will not go into specifics as to what is considered "S" canon or what items that are seemingly "C" canon are actually "G" canon.
Okay, I know that the novels are C-level, and I assume that most of the newer comics are also C-level. Where on the continuity spectrum to the Video games come in?
"...continuity "C" canon which is pretty much everything else. " By everything else I mean EVERYthing else. Novels, comics, junior novels, videogames, trading card games, roleplaying games, toys, websites, television. As I've mentioned earlier, any contradictions that arise are dealt on a case-by-case. This has been our general approach to continuity since we began using the Holocron database to track it.
In a nutshell, anything created by the author would be C-level. Anything in the the novels created by George Lucas (whether it comes from unpublished early script versions, unpublished author interviews with George, or George's revisions to the novelization manuscript) would be G-level unless contradicted by the films.
It gets a little more complicated when something is seen on-screen but not named. So the "shuura fruit" mentioned in the AOTC novel would be G because you see it in the film, although the author came up with the name.
Is there anything post-Return of the Jedi that is G level?
Not in the database, no. If there is anything anywhere, only George knows.
Though I don't discuss specific continuity issues in this thread, I do want to the address the fact that in the Holocron, we track continuity by Holocron entry and not by source.
What that means is, a particular source would never be discounted in its entirety, only those elements of that source that are contradictory.
Hence, while there may be individual elements of say the Marvel Comics or the Holiday Special that are considered non-continuity, all the other parts can still be valid.
Straight from the horse's mouth, in this case, Tasty Taste/Leeland Chee. The KEEPER of Canon and Continuity.
