- Using ODA for Translating Multimedia Information
-
- 1. Status of this Memo
-
- The purpose of this RFC is to inform implementors of multimedia
- systems about our experiences using ISO 8613: Office Document
- Architecture (ODA). Because ODA is being proposed as an encoding
- format for use in multimedia mail and file exchange, implementors
- wishing to use ODA in an open systems environment may profit from our
- experiences. This memo provides information for the Internet
- community. It does not specify any standard. Distribution of this
- memo is unlimited.
-
- 2. Overview
-
- ODA is a recently approved ISO (8613) and CCITT (T.410) standard for
- representing documents containing multifont text, raster images and
- geometric graphics. This encoding has been specified for use in a
- number of related standards, such as X.400.
-
- However, ODA is a very abstract standard, defining entities such as
- "composite logical object classes" and not common entities, such as
- "paragraphs". Therefore, effective use of ODA as an interchange
- medium requires the definition of a document application profile
- (dap) that defines some common entities and a map between ODA
- entities defined in the dap and entities used in the interchanged
- systems.
-
- 3. EXPRES Experiences
-
- The National Science Foundation funded the EXPRES project, which
- consisted of groups at Carnegie Mellon University (Information
- Technology Center) and the University of Michigan (Center for
- Information Technology Integration). These two groups collaborated
- with groups at McDonnell-Douglas Aerospace Information Systems, NIST,
- and Interleaf. Together, the five groups investigated the use of ODA
- as an interchange medium for submitting research proposals by
- electronic mail to the National Science Foundation.
-
- Part of the investigations yielded strategies for using ODA. We based
- our strategies on the NIST dap and the features provided by the
- Andrew, Diamond, and Interleaf systems. Our experiences been
- documented and published in a book [1]. The discussion may be
