For 2007, simplicity will continue to be a critical driver.
"Simplicity is one of the core values of ZK. In 2007, we will keep pushing ZK to the optimal goal: zero code," according to the roadmap, authored by ZK founder Tom Yeh.
"There are a few things that are special about ZK, from a design perspective," said ZK user Dietrich Kappe, in an email.
With ZK, markup and scripting are done in Java and designing becomes as simple as authoring HTML, the site says. Event-driven, server-centric components are featured to enable development as simple as programming desktops.
"The major rhythms of 2007 for ZK include ease of use, cross-platforms, cross-scripting languages, mega-components, and community collaboration," Yeh says on the roadmap.
"ZK has become the number 1 AJAX project in SourceForge.net, accumulated 250,000 downloads and 500,000 unique visitors and been referred by over 2,500 Web sites since the first release in November 2004," according to Yeh.
"In 2007 we would like to ignite more development of diversified plugins, versatile components, cool themes, design patterns, and sample applications," said Yeh.
"At the core, we will keep enhancing the extensibility with more flexible plugins, such [as] clustering and scripting languages, and the [long-awaited] Component Development Guide. With open source, people tend to modify the source codes directly, but please talk to us first," Yeh said.
As part of the roadmap, ZK Mobile, a Java Platform, Micro Edition client, is planned for release in the first half of this year. A visual design tool compatible with the Eclipse IDE also is on the agenda.
Core ZK developers work for Potix, Kappe said.
