A multimedia document is composed of different media objects. ISO's Op
en Document Architecture (ODA) proposes a standard multimedia document
model. However, the current ODA profile only includes static media, e
.g. text, geometric graphics and images. Because the future multimedia
documents not only include static media but also continuous media, e.
g. video and audio, continuous media document parts should be added to
have a complete multimedia document model. In this paper, we propose
a multimedia document model, which is derived from ODA's concept. The
proposed model is based on the object-oriented approach. Objects in th
e proposed document model are divided into two types: data objects and
pseudo objects. Data objects are data structures of a document; pseud
o objects are used to manage data objects. Based on the proposed model
, a multimedia document authoring and presenting system (MMDS) is also
developed on SUN SPARC workstations using the Solaris 2.X operating s
ystem.
