EMMA's Genesis: Building the Client

This presentation examines the development and implementation of EMMA over the past two years. EMMA
employs a variety of technologies, but “her” core is the XML markup language. The editor used for the
project is an open-source java editor called jEdit that we have modified for our purpose. The project then uses
Cocoon (part of the Apache XML open-source development project), an XML publishing framework running
on the Jakarta-Tomcat servlet engine. Cocoon is used to produce server-side XSL transformations of the
XML documents. In the initial phase of the project, Cocoon produces a variety of HTML displays, but we
continue to work toward using Cocoon as a complete document production and management environment that
will include PDF production, a rich search capability, and multiple document concatenation. Currently we are
using Filemaker Pro as the database for authentication and document tracking.
