- Dan,
-
- Thanks for your message. Obviously you know what you are doing with
- X11 browsers - we are impressed by what you have done to date. I was
- interested to hear that you are working on AVS - I have had some
- contact with AVS people at UNC.
-
- You make a good point that the world has been waiting for a good
- formatted text widget under Motif. One exists under NeXTStep, Robert
- Cailliau is just adapting one for the Mac for hypertext, but under
- Motif it has been lacking. Of course, hundreds of people have
- written them: all the word processors have them in, and products like
- dynaText, etc. However, there is none in the public domain.
-
- CERN like Convex has a copyright on all code, but we are doing our
- best to release W3 code as widely as possible, and possibly overcome
- this limitation. Why?
-
- The concept of the web is of universal readership. If you publish a
- document on the web, it is important that anyone who has access to it
- can read it and link to it. In order to make this possible, we don't
- need very new technology -- what we do need is
-
- 1. A common open naming/addressing format
- 2. Sufficiently powerful underlying protocols
- 3. Sufficiently powerful data formats
- 4. Some free implementations
-
- Now we have defined the (1), which did not exist before. We have
- supplemented the (2), where some protocols do exist. We have added a
- little to (3) though we will use all existing and new formats. We
- have written some code.
-
- You say your work would be of considerable valuer to convex. Yes,
- that is true. You must ask yourself whether it would be of more value
- to convex if kept private or released for general consumption. If you
- release it,
-
- - Convex gets the credit and a higher profile,
- (as Thinking Machines has with WAIS indexers for example).
-
- - Anyone in the world can read the information you supply
- with the same tool as they use for other information.
-
- - You get a lot of useful feedback from users on the network
-
- - A lot of people would be able to profit from what you have
- done
-
- You have to compare this scenario with that if you keep the code
- private. You will be able to use it internally. Would convex be able
- to profit from by selling it? If so, how many people would actually
- buy it? Will the AVS project benefit from a closed private
- documentation scheme?
-
- On these grounds alone, you may conclude that it is in Convex's
- interest to release the code. Still, you ask what we can "put on the
- table". If it would make it easier to justify the release of code,
- we would be happy to make all CERN-developed W3 code officially
- available to Convex under a more or less formal joint project
- agreement. Note that we are producing a parallel set of parsers and
- access mechanisms for HTML, newgroups, WAIS, prospero, etc. We have
- gateways, and other browsers. The line-mode browser you know, the Mac
- one is coming along, we may have a full-screen character grid browser
- too. We are currently unifying the browser architecture so that all
- access mechanisms can be used by all browsers. I'm not sure that
- either of our sides would want to be contractually bound to produce
- or maintain anything - the agreement would be just as-is code sharing
- of what exists when it exists, no strings.
-
- You ask about graphics. That cannot be our next priority, as we need
- to get the new architecure and general format negociation worked out.
- In many cases, we find that there are GIF/TIFF viewers on various
- platforms, and one can link in to them. We don't want to make a new
- graphics file format a la Mac/PICT, but we are intrerested in
- conversion code. Have you heard of editable Postscript? That might be
- what you are looking for. (See
- http://info.cern.ch/hypertext/Standards/PostScript/IPF.html)
-
- I don't know whether your company has a mechanism for allowing code
- to be released into the public domain (or General Public License). If
- it is politically impossible, then that's a pity. (We do have a
- group of students in Finland working on an X implementation, and if
- that doesn't work out we could write it ourselves. It may also be
- that more that one implementation with a different style will be
- interesting. Obviously it would be rather a duplication of effort,
- though we are under a lot of pressure from our management and users
- to put this at the top of the agenda.)
-
- I hope I have clarified the W3 team's philosophy, and perhaps
- convinced you to contribute, to our mutual (and the world's) benefit.
-
- Tim
-
- PS: Yes, I think you ought to be on www-talk, Dan. I'll put you on.
- The traffic is not too high.
