The problem of a model for representing multimedia documents and supporting operations on documents is addressed. Particular attention is given to the concept of type, since multimedia documents do not fit the static schema definition of database models. A syntax directed approach is proposed for the model. Three levels of specification for a multimedia document are discussed. The layout level describes the document presentation. The logical level describes the document semantic composition. The layout structure and the logical structure are compatible with the Office Document Architecture currently undergoing standardization (ISO, ECMA, CCITT).

Abstract
The problem of a model for representing multimedia documents and supporting operations on documents is addressed. Particular attention is given to the concept of type, since multimedia documents do not fit the static schema definition of database models. A syntax directed approach is proposed for the model. Three levels of specification for a multimedia document are discussed. The layout level describes the document presentation. The logical level describes the document semantic composition. The layout structure and the logical structure are compatible with the Office Document Architecture currently undergoing standardization (ISO, ECMA, CCITT).| File | Dimensione | Formato | |
