Systems and methods are disclosed that provide a framework, e.g., a Java®-based toolkit, that provides various levels of abstraction according to the needs of the designer. The abstraction levels are each associated with a set of packages that provide functionality suitable to the level. A user or designer accesses the level packages within the framework and employs the same to create a desired computer-readable media, e.g., a Blu-ray® disc or “BD”. Other aspects may provide corresponding or complementary functionality. For example, the framework abstracts drawing or graphics primitives to higher-level entities, allowing the same to be easily employed in the creation of arbitrary graphical elements. In another example, a business logic module may be employed which can be customized by using settings files.
