LIMITED DISTRIBUTION: FOR XEROX INTERNAL USETowards an Interchange Standardfor Editable Documentsby Jim Mitchell (Mitchell.PA) and Jim Horning (Horning.PA)Version 1.3/August 31, 1982The Interscript standard will define a digital representation of editable documents forexchange among different editing systems. A script is the representation of a document inthe Interscript format; it can be transmitted from one editor to another over a network, orcan be stored for later editing. A script is not limited to any particular editor: if a scriptcontains editable information some of which is not understandable by a particular editor, it isstill possible to edit the parts of the document understood by that editor without losing orinvalidating the parts it does not understand.This draft is a proposal for the technical content of the Interscript standard. It defines andexplains the proposed standard, gives examples of its use, explains how to externalizedocuments from an editor's private format as scripts, and how to internalize scripts into aneditor's private format. It also indicates a number of issues that must still be resolved toestablish a practical standard.Note:This draft is being circulated to interested parties within Xeroxto report preliminary ideas. It should not be interpreted as a definitiveproposal, and should not be distributed outside.XEROXPALO ALTO RESEARCH CENTERCOMPUTER SCIENCE LABORATORY3333 Coyote Hill Road / Palo Alto / California 94304 ge0f@p{,+W;qTy gLXrX: gI  gFsr sD gDZ ts( gB": gA ? g?d2- g=0, g<. g9 R g7f ?t g5sAt s g4A g2pS/hrIs4 S--S,0(`u(`r(`S(`v! ge>QS HELVETICA HELVETICA HELVETICA  HELVETICA  HELVETICA LOGO HELVETICANj/sinterscript-title.bravomitchellAugust 31, 1982 4:27 PM
