Rhizome is an application stack for building RDF-based applications and web sites implemented in Python. It includes: RxPath, a RDF data engine that allows XSLT, Schematron and other XPath-based languages to directly access RDF stores; Raccoon, an application server; and Rhizome Wiki, a Wiki-like content management and delivery system that brings the Wiki approach to building dynamic web sites. What's new? Major changes since last announced release (0.5.1): Rhizome Wiki: * major performance enhancements: several times faster * now supports GRDDL and "shredding", a framework for extracting RDF from content and maintaining the relationship over time. * better support for viewing and editing RDF directly with most RDF formats (RDF/XML, NTriples, Turtle). * new UI for editing users and roles * more Wiki features, including tracking missing pages and page and comment spam detection via the Akismet service RxPath: * much faster: now uses a simple but optimizing query engine * support for RDF named graphs (RDF contexts) * better support for using RxPath in XML contexts (e.g. an XSLT page) * better support 3rd party RDF libraries and RDF stores In addition, there have been many other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details. More Info: * RxPath provides a deterministic mapping between the RDF abstract syntax to the XPath data model, allowing you to query, transform, update and validate a RDF model with languages syntactically identical to XPath, XSL, XUpdate and Schematron. * 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. Rhizome uses: * ZML, 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, an alternative XML serialization for RDF that is designed for easy authoring in ZML, allowing novices to author and edit RDF metadata.

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 approach to building dynamic web sites. What's new? Major changes since last announced release (0.4.3): * RxPath's RDF mapping has been applied to Schematron, enabling a Schematron schema to be used to validate a RDF model. * The Raccoon application server has been signficantly restructured, new features include: - applications can now use XML (in addition to RDF) data stores. - added SQL-like triggers for changes to the data store. - added a two-phase commit transaction coordinator. - enable multiple applications to run in one Raccoon process, each owning part of the URL namespace. * Rhizome enhancements include: - Sports a new look and feel provided by a new, more usable and polished default theme. - The authorization schema has been made considerably more flexible and expressive, enabling all changes to the RDF data store to now be authorized. - In addition, all changes to the data store are now incrementally validated by a Schematron schema. In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt <http://rx4rdf.liminalzone.org/changelog.txt> for more details. More Info: * 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, update and validate a RDF model with languages syntactically indentical to XPath, XSL, XUpdate and Schematron. ** 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.

Rx4RDF is application stack for building RDF-based applications and web sites. Rhizome is a Wiki-like content management and delivery system built on Rx4RDF that enables the Wiki metaphor to be used to rapidly build dynamic web sites. What's new? (Since 0.3.0 -- I never got around to announcing 0.4.0.) 0.4.0: Rhizome gains full-text indexing, browsing and grouping by keyword, summary views, better support for RDF/XML, diffing in revisions view, and several usability enhancements. Raccoon gets several improvements to performance, security, and error handling. RxML and ZML syntax has been made more user-friendly with simpler syntax and better documentation. 0.4.1: RxPath adds support for RDFLib, if installed. Throughout all sub-systems: get non-ASCII content working. In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details. More Info: * 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.

Rx4RDF is application stack for building RDF-based applications and web sites. Rhizome is a Wiki-like content management and delivery system built on Rx4RDF that generalizes the wiki concept in several ways. What's new? This release is focused on making Rhizome usable for running small-scale web sites: * Much improved documentation, including manuals for Rhizome, Raccoon and ZML. * Many features added to Rhizome -- it now has (nearly) all the functionality you'd expect in a full-featured Wiki. It also much easier to browse and edit the underlying RDF model (and the default template is less ugly). * Raccoon's security has been enhanced by disabling potentially dangerous settings by default and by the creation of an audit log of changes to the database. Rhizome now supports fine-grained authorization of the changes to the RDF model and provides a secure default authorization schema. In addition, there have several other enhancements, see http://rx4rdf.liminalzone.org/changelog.txt for more details.
