Categories, article types, tags and core entities

FLASHGALE uses a two-layer editorial taxonomy. The first layer is the public section structure. The second layer contains the subcategories, article classes, tags and covered objects that help readers move through the subject cleanly and help editors keep language consistent over time.

First-level sections
