Plone is a content management system that is simple to set up, maintain, and modify. It is designed to be a corporate-ready content management system. It is ideal as an intranet and extranet server, as a document/Web publishing system, and as a groupware tool for collaboration between separately located entities. It aims to be a proper content management and publishing system, sharing the same qualities as Teamsite, Livelink, and Documentum.
Silva is a CMS for organizations that manage multiple or complex Web sites. Content is stored in clean XML, independent of layout and presentation. Features include versioning, a workflow system, an integral visual editor, content reuse, sophisticated access control, multi-site management, extensive import/export facilities, fine-grained templating, and hi-res image storage and manipulation. Silva is built on top of the Zope Web application platform.
Kraken is an application for managing knowledge objects, which can be documents, remote or locally cached Web pages, personal information, todo list items, appointments, and so on. It is especially useful for researchers or students to manage their information. Users can annotate these knowledge objects with metadata, perform complex queries, and present the results as HTML pages. Kraken uses RDF as its native format, allowing its data to be easily read by external applications.
Conflux is Web-based groupware and collaboration software. It offers a shared central document repository, shared calendars, tasks and contacts, and an email client. It has support for Unicode, multiple languages, and date/time formats for the English, German, and Estonian languages. Access rights are offered in hierarchical (group) form.
Drugref is a collaborative effort to create and maintain a database of pharmaceutical reference information, tagged by language, country, and reference source. A Web interface written in PHP4 allows the community of health professionals to maintain and review content. The database structure, implemented in PostgreSQL, is designed to facilitate automated decision support. "Tagging" allows one to import information from any source in parallel, thus allowing drugref to work as a generic interface to any kind of (comercially or freely) available drug reference information.
Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.
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.
