Motivations

• To provide support for the design of Hypermedia applications

• To provide support for fast prototyping of Hypermedia applications

The tools can be the basis for additional services provided to publishers

• Software integration

• Data Base integration

• Multi-application Environment

Integration in the SIT-MOON architecture (1)

Software integrationThe suite of tools is made accessible from within the Sitmoon environment, with a button, a menu, etc.

Simple and useful

Data Base integrationThe DB of nodes visualized by JWeb

– Within the Director environment of Sit-Moon, a special function allows to save the editing results (a node for a JWeb application) in the proper Database (CARAT)

– when a node must be inserted in the JWeb Database, Director or CARAT is used to locate something previously created within the Sitmoon environment.

Less useful

Multi-application Environment• a coordinator environment, within Sitmoon, manages several applications (The current suite of JWeb is mono application)

• Applications are localized by logical names, rather than physical files.

• The user of such a coordinator environment, first of all will choose the application, and from there activate the different JWeb tools.

• The coordinator environment would be responsible for creating a new application, deleting an application, moving pieces from one application to another
