Archetypes is a framework for developing new content types in Plone. The power of Archetypes is first in automatically generating forms, second in providing a library of stock field types, form widgets, and field validators, third in easily integrating custom fields, widgets, and validators, and fourth in automating transformations of rich content.
Java+ is a Java preprocessor that adds its features to any Java compiler. It has long, multi-line strings with executable inclusions like Perl or Ruby, optionally segregates Java+ strings into ResourceBundle files, eliminates the need for JSP or ASP and their implied need for Java compilers on deployment servers (a security concern), and adds absolutely no overhead in either space or time. There are graphical and command line interfaces, and a simple, general, and recursive string syntax.
The zen Platform is a Java development environment for J2SE/J2EE. It eases and accelerates the Java application development by visual methods (RAD). Complete applications can be modelled in an intuitive fashion without the need for technical expertise. The complexity of Java and J2EE programming is tremendously hidden - reducing the learning curve for Java novices. Java experts are by no means restricted - they may apply their knowledge without limitations. Application flexibility is a core feature of the platform, which is delivered as an Eclipse plugin.
Expose is a PHP template engine. It supports server and client-sided caching, a plugin system (to simplify common tasks like inserting a date picker) and internationalization (to write templates in multiple languages using external translation files). Unlike most template engines, Expose's template script language is based on PHP itself, which means you don't have to learn a new syntax. You can use most of the PHP language elements and functions in the way with which you're familiar.
BabelKit is an interface to a universal multilingual database code table. It takes all of the programming work out of maintaining multiple database code definition sets in multiple languages. The code administration and translation page lets developers define new virtual code tables, new languages, enter all codes and their descriptions, and then translate them into all languages of interest. Perl and PHP classes retrieve the code descriptions and automatically generate HTML code selection elements in the user's language. This makes internationalization and localization of Web sites and database interfaces much easier.
HEBCI is a technique that allows a Web form handler to transparently detect the character set with which its data was encoded. By using carefully-chosen character references, the browser's encoding can be inferred. Thus, it is possible to guarantee that data is in a standard encoding without relying on (often unreliable) Web server/browser encoding interactions.
