You ask a good question. Currently, all we do with existing WWW software is as
you describe: you need write access to annote it. See
www http://info.cern.ch/hypertext/WWW/DesignIssues/LinkToLiving.html
and
www http://info.cern.ch/hypertext/WWW/DesignIssues/Multiuser.html
for discussions in this area. We would like to include facilities in the
new protocol to allow front-end update.
One observation I have made is that many nodes are basically lists, and the
option to add a link to the list could be a simple and safer operation than
allowing full write acess.
The function would be annotate(docid1, docid2) which would, in the simplest
hypertext case, add a bit of text to the end of doc1 consisting of the title
of doc2, linked to doc2 itself. This function would give allow a "reply"
feature when used on a mail message. For a newsgroup, it would equate to
"post". obviously it would be up to a server how it would impelement it (ity
could maintain alphabestical order for example, it could store the links in a
separate databse, it could formatthem anyway) -- the requirement would only be
that at the end, a link from doc1 to doc2 existed.
I'd be interested in CSCW people getting involved with the web. Certain servers
could for example mention their ability to support concurrent editing of
documents for clients which support that.
