The Collection Description is a subtype of the Package Description that has added structures to better handle the complex Content Information of an AIC. The Collection Description, which is modeled in figure 4-24, contains the information classes that are contained in the Unit Description. There are two types of Associated Description in a Collection Description:

  • There is one Overview Description that describes the collection as a whole (i.e., the top-level collection in a model of objects for transfer (MOT).
  • There are zero or more Member Descriptions that separately describe each member of the collection (i.e., child collections in a model of objects for transfer (MOT)
