Ductus is a wiki system designed to handle arbitrarily-structured content and a variety of workflows. With Ductus, programmers can easily define classes of structured content, providing rich mechanisms for user interaction. For instance, the Wikiotics project uses Ductus to allow people to collaborate on "language lessons," which can later be used as quizzes or flashcards. Such modes of interaction are not possible with most wikis, which are designed primarily to handle freely-structured text.
WebBot is a Web development toolset which is designed to sit nicely on top of your existing infrastructure. It is built with a collection of Open Source tools which together enable building Python Web applications the same way native ones are built and running these applications on top of the leading Python frameworks (such as Django and Google's App Engine). As a result, the WebBot framework encourages reuse, concise code, rapid development, and happy developers.
CheckApp will serve as a basis for a free (as in freedom and as in beer) social network, so that anyone will be able to check out and modify the code, or deploy this application in their own server. It will also try to minimize the usage of personal information, so there would be no privacy problems.
