    Just for fun, I called Doug to see if he could shed light on the definitions
    of these terms. Here's what I got:

     Hyperdocument: "The knowledge container. No one says it has to be a file,
    any container."

     Dynamic Knowledge Repository: "The handbook, the conversations and
         the contents. Dynamically up to date representing the state of the
         If you want more depth, you can trace back and find the evolution of
    that in
         the record."

     OHS : "A toolset with the structure and properties of the knowledge
         containers plus the functions that you can execute on them, including
         traveling, linking, editing, etc. Includes auxilliary languages,
    compilers, tools,
         user interface. Does not include the contents of documents itself,
         only how you structure and operate on them."

     HyperScope: "Part of the OHS, that you can implement early and get
          utility in the context of legacy files. As it evolves to add more
          (e.g. backlinking, editing), it becomes a bigger part of the OHS."

    OHS to me now seems almost like the term "MS Windows", which contains the
    system, the look and feel, the philosophy, as well as a set of included
    tools such
    as the web browser or media player. But it appears OHS does not represent
    the content
    of the knowledge repository or containers (documents).

    Doug was thrilled to be asked about it and was happy that we are having
    about this because he emphasized how working through terms is an essential
    of cooperative knowledge work.

    Thanks for looking into that, Adam.
    Good to know that I hadn't just missed something obvious.

    Consistent terminology makes sense. It's the only tool we
    have to attack the problem with.

    I am totally in love with:
      HyperScope -- the viewer
      HyperDocument -- the thing viewed (a "slice" taken
         from a repository)
      Open HyperDocument Repository -- where they are kept
      OHS: HyperScope + OHR + HyperDocuments

    At the moment, I continue to reserve the term "DKR" for
    future developments. Jack and Howard are constructing
    the ontology for the OHS, and we need that. But later on
    they are going to want to build bigger and better
    ontologies to solve even deeper problems (yes?).

    I know that the OHS as currently envisioned will solve
    a lot of problems, and provide us with the ability to
    carry on intelligent, far-ranging discussions that can
    eventually "coalesce" to reach one or more conclusions.

    I'm not yet convinced, however, that it will give Jack
    and Howard *all* the tools they need to play with
    bigger and better ontologies -- to construct them,
    operate on them, and use them to deal with information
    in meaningful ways. Much as I want to see the capability
    come into existence, it is not all clear to me that the
    current design will be capable of doing that.

    So I tend to use DKR for that still-nebulous thing we
    hope to get to sometime downstream. In many ways, it
    is a label for my ignorance -- for all the things I
    have to understand about what we need, and about how
    to provide them. (The difficulty I have in following
    ontology-related discussions convinces me that the
    system I understand (the OHS) is unlikely to qualify
    as a DKR.)

    [BTW: When I reply to your messages, the automatic
    quoting feature does not seem to work. Perhaps because
    it is in HTML form? Or do you use IE, and it is doing
    something that is incompatible with Netscape's quoting
