Canon

Star Wars canon depicts anything that has been officially published. Canon is unofficial, but reliable.

The New Jedi Order and Knights of the Old Republic are examples of canon material.

Star Wars: Exodus does not normally go into canon references. However, several things revolving around the community are, at least, linked to canon material. Please visit Wookieepedia, Star Wars.com, and the Completely Unofficial Encyclopedia for your canon material needs.
