WebWisdom is a JavaScript (and some CGI) based system for managing hierarchically arranged information such as you get in Education as you span lectures, courses, degrees, departments, Universities. The database available here illustrates 3 worlds:

Administration,
The Virtual University with Courses(electronic foils) and the

Virtual Family (photo sets)

The Tree of Wisdom

You mean WebWisdomNT. This is not a new version of Tango but a "Virtual University" database that is designed to work very well with Tango. Tango and WebWisdomNT are standalone products but the power of product and patent comes from linkage There is only one version of Tango as we evolve Tango1.0 to 2.0 > Which one do you (and if there are other inventors) prefer?

Client side sends essentially a URL to servlet. The URL specifies version of material wanted and this choice currently made on client What you describe above is Tango's typical way of sharing a server side (CGI or its Java equivalent the servlet) object > > > > > > > 4) A class is Tango Server (Tango1) or room (Tango 2) > > Teacher and students log in.

(sorry for the run-on) What you say is true but what I meant is that each page has a "NEXT" button constructed by servlet when it produced page.So database/servlet define what next is, teacher invokes it in way you describe > > > Slaves map URL for two reasons > > 1) Change source of material to a "mirror site" such as local web server or CDROM on > > what's meant here?
