Objectives and Approach

The purpose of the HYTEA project is to implement a set of tools to support the development of large and complex hypertext/hypermedia applications.

The target of the project is applications which exhibit a number of specific features: the body of information to be represented is very large and complex; the authoring effort is long-lasting (continuous maintenance or updates); and there is a clear-cut distinction between authors and readers.

For applications with the above features, authors need support in several respects:

• an application-oriented model to define the structure (ie the schema) of the applications
• an application-oriented model to define the objects (ie instances) which populate the application
• a way to "translate" the application developed with the above model into an implementation model (the features of which can be exemplified by the Dexter reference model for hypertext systems)
• tools to support all these phases: specification, design, development, debugging, maintenance, etc.

The expected results of HYTEA are:

• an application-oriented model to describe schemas of hypertext applications
• an application-oriented model to represent an application according to a predefined schema
• a model to translate the representations defined at above into an implementation with a conventional hypertext system
• tools to support the definition of schemas, the modelling of an application, the "translation" of the application into a conventional application, and the maintenance of that application
• a number of prototype applications.

Different media will be supported (both in the model and in the tools): text, still graphics, animated graphics, sound, still images, video images, etc. The implementation environment will support a number of different standards and technologies: CD, CD-I, DVI, etc.

End-users are directly involved in the project.
