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.
Rx4RDF is a set of technologies designed to make W3C's RDF less complex and easier to use. It includes RxPath, which enables one to use familar XML technologies like XPath, XSLT, and XUpdate to query, transform and update an RDF model, Raccoon, an application server that uses an RDF model for its data store and RxPath to translate arbitrary requests to RDF resources, and ZML and RxML, alternative text formats for XML and RDF that were designed to allow novices to write XML and RDF with (nearly) the same ease as a Wiki entry.
Rhizome is a Wiki-like content management and delivery system that exposes the entire site including content, structure, and metadata as editable RDF. This means that instead of creating a site with URLs that correspond to a page of HTML, you can create URLs that represent just about anything. It was designed to enable non-technical users to create these representations in an easy, ad-hoc manner. For developers, this allows both content and structure to be easily repurposed and complex Web applications to be rapidly developed.
