- First of all, hearty congrats to the WWW people. It's a great tool, and
- since it is based on SGML, it has the broadest scope of any solution I have
- yet seen.
-
- To others, see the current issue of Byte magazine regarding "Info-Glut" and
- SGML. Interesting.
-
- ----------------------
-
- I have a few recommendations regarding new link types in WWW. This is based
- on thinking about hyper-applications for almost 15 years, (ever since I
- first had the pleasure of hearing Ted Nelson speak in 1977.)
-
- First though, there are a few ideas which I feel should be mentioned to 'set
- the stage' for my list.
-
- Transparent Documents --
-
- a transparent document is one which a user creates locally,
- and that is a new representation of an existant document.
- Transparent documents are used to create new local links on
- a document which I do not have permission to modify.
-
- Transparent documents can then be made available to others,
- (published) just as a "regular" document is, thus facilitating
- the creation of new works from old.
-
- User Documents --
-
- a user document is where I keep my "bookmarks", links to
- local documents, links to messages from others, links to
- my "attention" links, (see below). User documents are where
- we, as navigators of the docuverse, are defined as individuals.
-
- They are also where we can keep links to other user documents
- which have been permitted to view/modify my own local documents.
-
- Another function of the User document is to collect users into
- an abstract group. (Thus, based on my membership in user
- document 'Research Group', I am permitted access to materials
- 'owned' by that group. Of course, messages sent to an abstract
- group then become available to all members of that group.)
-
- (Please note that a User Document is nothing more or less than
- a collection of links, (as all documents are).)
-
- ------------------
-
- Now, on to my list of link types....
-
- There are 4 'minimal' link types which, I believe, a useful h-app *must*
- support.
-
- 1. Replacement
- -- when activated, replaces the current document
- with a new document.
-
- 2. Annotation
- -- when activated, overlays a new document on the
- current document, partially obscuring the original.
-
- 3. Inclusion
- -- when the document is created, elements from other
- documents are collection to be included in the
- representation of the current document. (Quotes)
-
- 4. Expansion
- -- when activated, new information is added to the
- current document, expanding the original scope.
- (Think of outline processors, and the collapse
- of detail.) This is also a reflection of
- Nelson's concept of 'stretch text'. (Stretch text
- is where a sentence is constructed in such a
- way that when it is collapsed it states it's thesis
- in simple terms, and when expanded adds detail to
- further express itself.
-
- There are 3 further types which I believe are necessary to complete the
- function paradigm.
-
-
- 6. Execution
-
- -- when activated, some arbitrary function is performed.
- The point that was mentioned about the lack of an
- ubiquitious scripting language is well made. Lisp
- is too arcane for most. Shell languages are too
- platform specific. What is needed is a simple
- to understand, freely available scripting platform.
- Although I hesitate to mention it, REXX might be
- a reasonable choice due to it's broad availability.
-
- 5. Attention (a specialisation of the Execution type)
-
- -- when the current document is modified (a link is
- added, or removed, or the document is merely read)
- a message is sent to the 'owner' of the attention
- link. This message creates a new link in the 'user
- document' of the individual who placed the attention.
-
- In this way, I could place a link onto a document I
- had interest in, and when it was changed or accessed in some manner, I would be informed.
-
- 7. Collection (a non-local specialisation of the Execution type)
-
- -- when activated, a collection link leaves the current
- document, and 'travels' the docuverse, in search of
- other documents which satisfy it's internal criteria.
- This is the concept of a 'knowbot'.
-
- Collection links can be activated based on day and
- time, much like the WAIS questions in the MAC
- WAIS interface, WAIS-Station. They could also be
- activated based on external events, such as the
- activation of an attention link.
-
- Collection links would be written in the ubiquitious
- scripting language, and would only be allowed to
- operate on documents which were EXPLICITLY permitted.
-
-
- ----------------------------
-
-
- One of the missing pieces here is the ability of creating new h-texts, and
- adding new links to old h-texts.
-
- Hypertext, and like systems, are of limited use if they do not support
- collaboration. I feel that this is a VERY important point.
-
-
- ----------------------------
-
- So.....
-
- Scenerio:
-
- I start my session with my h-app, and open my user
- document.
-
- I notice that 17 of my attention links have been activated
- in the last day.
-
- I select the most interesting and activate the link which
- it created in my personal user document.
-
- I am now reading an article which I previously linked, and
- see that an annotation which I made some time ago has been
- added to, by a colleague.
-
- The comments are pertinant to my current work, so I create
- a new local 'transparent' document to mirror the original
- work.
-
- On this new document, I make a few new annotations and decide
- to made this new work available to the research group of which
- I am leader. I place a link to it in the user document which
- represents my working group.
-
- I also send a new document link to the colleague who made the
- original comments, so that he can see how I have interpreted
- his ideas, and included them into my own research.
-
- I move ever onwards...
-
- ---------------------
-
- Ok, I hope that that fuels a little discussion, and I would *love* to hear
- from others regarding these ideas.
-
- (Yes, some of what I have talked about here exists, in various forms, on my
- own personal system, but I would be *very* interested in hearing from
- developers who might be interested in making something real and useful from
- it. I, sadly, have too little time to make these ideas real. My ultimate
- goal would be to make the realisation of these ideas available in the public
- domain.)
