eContent is a Web-based content management system for creating information systems, intranets, B2B, B2C, catalogs, and vertical portals. Written in Java for scalability, and based on open standards Struts and Expresso for stability, eContent integrates content management, scalable content and application delivery, resource management, workflow and personalization. It supports executables, all documents types, OLAP reports, Java programs, and legacy integration.
TWiki is a flexible, powerful, and simple Web based collaboration platform. It is suitable for dynamic intranets and knowledge bases, and for sharing and managing documents and collaborative projects. It resembles a normal Web site, but every page can be changed from a browser. It features automatic link generation, full text search, group authorization, Web forms, reporting, change notification, file attachments, revision control of pages and attachments, a modular templating system with skins, hierarchical navigation based on the topic parenting feature, and more. Plugins can be used to enhance the program and build groupware applications.
Docpile is a PHP-based document management system that allows multiple people to share documents and keep track of revisions. Users can upload and download documents, grant per-file, -user, or -folder access privileges, and send notification emails when documents are being updated. Administrators can create access groups, each responsible for a different set of folders and users.
The Enhanced File Crypt/eXtended File Stealth System (EFC/XFSS) makes your uploaded files safe on the server so that no one can read them without knowing a few details to decipher the files. It generates different obfuscated names and encrypted files so no one will know what the original format or name was.
PhotoFS is a Web-based photo album or image gallery, based on the files-as-directories and attributes-as-files concepts at the core of the ReiserFS 4 filesystem. It does not require ReiserFS 4, but is much more efficient on that system than on others. It does many of the same things as other Web galleries, at least as far as the basics go. What makes it different is its use of the filesystem instead of a database. It allows you to use regular unix tools to access your photo collection. It can handle very large collections, and also encourages multiple categories per file, deep category hierarchies, and batch processing.
