Abstract
A library can store different types of multimedia objects, including effects (for example, behaviors, filters, fonts, and particle effects) and content (for example, audio clips, video clips, and still images). The library can store both pre-defined objects and objects that have been created by a user. The library is extensible, so that it can store objects of unknown type.
