Abstract
A data structure is disclosed in which stored objects in a computer system can be extended. The data structure contains a header containing encapsulation information related to the stored object, data describing the essential elements of the object, and at least one subobject extending the description of the object. Header information includes metafile identification, version and revision numbers, endian code information as to the ordering significance of the stored data and a table of contents. Encapsulation information describes the size and type of the individual objects. Essential elements and extensibility data permit additional attribute information to be used and shared among applications which utilize the object.
