Development background of bvio
Bvio is an encyclopedia using a handy hypertext algorithm presently called wiki.
The idea of using freely editable encyclopedia used to be common when the first HTTPD servers came in the early 1990s (later, then companies became to interested in, it became less open and free. Then, wiki became widely used).
I tried to make a freely editable and open hypertext system using Perl since 1995, but could not finish it. We have tried a self-editable perl CGI programs etc (which is now actually available developed by some other people).
From 2005, Bvio is using a slightly modified Mediawiki.
