LIMITED DISTRIBUTION: FOR XEROX INTERNAL USE

Towards an Interchange Standard
for Editable Documents

by Jim Mitchell (Mitchell.PA) and Jim Horning (Horning.PA)

Revision 1/May 4, 1982

The Interdoc standard will define a digital representation of editable documents for exchange among different editing systems. An Interdoc script can be transmitted from one editor to another over a network, or can be stored for later editing. A script in Interdoc is not limited to any particular editor: if a script contains editable information some of which is not understandable by a particular editor, it is still possible to edit the parts of the document understood by that editor without losing or invalidating the parts it does not understand.

This document is a draft of a proposal for the technical content of the Interdoc standard. It defines and explains the proposed standard, gives examples of its use, explains how to transcribe from an editor’s private format into scripts, and how to render scripts into an editor’s private format. It also indicates a number of issues that must still be resolved to establish a practical standard.

Note:This draft is being circulated to interested parties within Xerox to report preliminary ideas. It should not be interpreted as a definitive proposal, and should not be distributed outside.
