MEDIA DESIGN IN*PROGRESS RELEASES INTERACTION 4.0 FOR MAC

SAN DIEGO CA, May 2, 2002: Media Design in*Progress releases the
Interaction 4.0 XML/XSL BASED WEB APPLICATION SERVER FOR MACINTOSH. The new
release adds support for WebStar V on MacOSX, Mac Web Sharing, Apache and
other web servers on UNIX and Windows, dramatically expanding the number of
sites that can take advantage of Interaction. A 30 day trial version is
available from:

http://interaction.in-progress.com

Interaction generates standard HTML and WAP pages from server-side XML and
XSL or CSS2 style sheets. Legacy HTML documents can be used as is or
enhanced with XML constructs, facilitating a smooth transition from HTML to
Extensible HTML and XML.

Extensible Stylesheet Language (XSL) is a standard from the World Wide Web
Consortium (W3C) used to build templates and transformations for the layout
of web pages. Cascading Stylesheets Level 2 (CSS2) is a W3C standard for
designing the presentation style of a web page.

The new release includes revised versions of the complementary Forum and
Chat services, with support for themes to design of the appearance of web
message boards and chat rooms. A theme is a set of XSL stylesheets or HTML
templates that controls the layout and style of the pages of a service.

Shipping since 1995, Interaction provides a mature, reasonably priced and
easy to use Mac alternative to expensive site management and dynamic
publishing systems. The application server uses XML and XSL to maintain a
strict separation between content, processing and presentation, making
websites more flexible, facilitating reuse and allowing a centralized
consistent design of the look & feel of the pages.

Press package, review copies and screen shots for Interaction 4.0 are
available upon request.
