The OpenInsight for Web Development Toolkit (O4W) makes it possible for OI programmers with limited or no HTML/XML/javascript experience to develop feature rich web pages. O4W is designed to work the way OpenInsight developers think, taking advantage of the skills and knowledge they already have. While users with more web development experience can use O4W's advanced features, all developers can create modern web applications (using javaScript, XHTML, and AJAX) through O4W's APIs.
