Rx4RDF is application stack for building RDF-based applications and web sites implemented in Python. Rhizome is a Wiki-like content management and delivery system built on Rx4RDF that brings the Wiki metaphor to building dynamic web sites.
Major changes since last announced release (0.4.1):
- Support for RDF Schema (subclasses and subproperties) - Added a UI for adding comments and several other UI improvements - Added a notion of themes to ease customization of look and feel. - More security enhancements including sanitizing HTML and supporting Google's new anti-comment spam standard. - Smoother installation and command line handling. - Compatibility with 4Suite 1.0a4 (enables OS X support).
In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details.
* Rx4RDF is a set of technologies designed to make RDF more accessible and easier to use. It includes:
** RxPath provides a deterministic mapping between the RDF abstract syntax to the XPath data model, allowing you to query, transform and update a RDF model with languages syntactically indentical to XPath, XSLT and XUpdate (dubbed RxPath, RxSLT, and RxUpdate respectively).
** ZML is a Wiki-like text formatting language that lets you write arbitrary XML or HTML (using Python-esque indentation rules), enabling you to author XML documents with (nearly) the same ease as a Wiki entry.
** RxML is an alternative XML serialization for RDF that is designed for easy authoring in ZML, allowing novices to author and edit RDF metadata.
* Raccoon is a simple application server that uses an RDF model for its data store, roughly analogous to RDF as Apache Cocoon is to XML. Raccoon uses RxPath to translate arbitrary requests (currently HTTP, XML-RPC and command line arguments) to RDF resources, each of which can be associated with RxSLT and RxUpdate stylesheets.
* Rhizome is a Wiki-like content management and delivery system built on Raccoon that takes the concept of the Wiki to the next level: everything is editable, not just content but its meta-data and behavior, even the structure of the site itself. Furthermore, Wiki entries are abstract globally unique RDF resources that can have any kind of content and whose presentation is contextual.
