OnlineCourse is a Zope Product that allows you to implement a web based distance learning application. Main features include an online chat classroom, message board, upload of course materials from MSWord .doc files, log of student participation, and provisions for assignment entry, homework entry, and grading.
NuxUserGroups is a Zope product that adds the notion of groups of users. Groups provide a level of indirection in the user -> roles mapping, which provides greater flexibility. The groups are defined and managed in the User Folder. They are then used at the local roles level, where you can define an additional mapping of groups -> roles, thus giving the users who belong to these groups additionnal local roles. A workgroup can be defined simply and managed in a centralized manner.
ZShellScripts extends Zope scripting by allowing developers to interface with other language interpreters. It currently supports Python, Perl, PHP, Ruby, Lisp, and Unix (Bash) scripts which can be executed from within Zope with semi-transparent access to Zope's variables and objects. It is designed to encourage people to invent new ways to deal with Zope and its object database by providing a common base infrastructure.
With Zope Object Files and the 'zof_install' associated script, you can work on Zope objects directly on the filesystem and install them to a Zope server with a simple makefile (exporting is also provided). Meta-data instances are stored in a simple XML file with pointers to data documents. It is used in production, but some objects do not work.
HamCannon is a Zope/Plone product for managing outbound email marketing. HamCannon is designed for sending ham, not spam: it has much support for helping users unsubscribe and none for hiding from them. HamCannon provides all of the tools required to produce personalized email newsletters or other email marketing, with subscription management, open tracking, bounce tracking and link tracking, complete statistical reporting and complete personalization, limited only by your data.
Aiakos is an innovative distributed authentication system, based on Zope and Plone. Much of the heavy lifting is done using the LDAPUserFolder product by Jens Vagelpohl. Aiakos allows you to provide a central sign-on system for a network of Web sites. All login and registration activity takes place on the central Aiakos server. Participating sites receive encrypted authentication packages from the authentication server, with which they can authenticate users.
