55    Hypermedia on the desktop would be useful for
56    keeping hyperlinked notes, for referring to
57    pieces of documents in discussion, or to
58    refer from a short memo to a document
59    with more in-depth information.

65  We believe that a major reason is that such links  We believe that a major burden to hypermedia
66  would break when documents are published, moved  on the desktop is that links break when documents
67  between folders, or sent by email. Changing all the links  are published, moved between folders, or sent by email.
68  when moving a document is too inconvenient.  
69    When sending a couple of hyperlinked notes per
70    mail, the receiver would have to assemble them
71    into the sender's directory structure. A document
72    collaboratively authored by sender and receiver
73    could not be linked to, except if both parties
74    place it in exactly the same directory.

82    on the Web, it would have the same URI [XXX] as on the

84    the receiver could follow the link as long as their
