HYPERTEXT INTERCHANGE USING ICA

Interchange of text and hypertext between various systems is vital in order to reuse text and hypertext, but the task of generating translat ors between different representations is often complex and tedious. Th e Integrated Chameleon Architecture (ICA) is a public domain toolset f or generating translators. However, ICA can only handle context-free g rammars while the grammar of hypertext is not context-free. This paper presents an extended ICA (E-ICA) which is based on ICA with extra pre - and post-processors to handle the context-sensitive and implicit inf ormation of hypertext. A system called SGML-MUCH has been developed us ing E-ICA. The development and use of the SGML-MUCH system is presente d as a case study with converters for the hypertext systems MUCH, Guid e, Hyperties, and Toolbook described in detail.
