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.
Keylime for Zope is a set of generic objects to facilitate fast SQL application development. It offers the following objects, which can be used or overridden: htmlView, htmlInsert, formInsert, formUpdate, and htmlDelete. It uses Folder properties to define sqlTable, sqlKey, and sqlUniq so that the application will function using generic or overridden forms. Infinitely hierarchical SQL applications can be written very quickly. Sample apps and a Zope installation guide are included.
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.
EZ Reusable Objects (EZRO) is a Web application that can be used by non-technical staff to manage content as "objects." Content objects containing text, video, and audio can be shared, modified, and re-styled to appear via a traditional Web site, an on-line course, an innovative "Coach," or as a community of interest site. It is highly scalable and can be used for public Web sites, secure environments, and private intra/extranets.

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.
