Damian Steer has created RDFAuthor, an application for Mac OS X that enables the visual authoring and querying of RDF instance data.

RDFAuthor also supports data querying. Two incredibly pretty tutorials demonstrate its use. The application is written in Java, using Apple's Cocoa framework. Source code is available, although Steer has not yet determined a license for the application.

• Meanwhile, work continues in the RDFCore Working Group. In particular Brian McBride has announced the WG's resolution that anonymous resources (now cryptically called bNodes) are part of an RDF graph. Full details are available on the RDF Issue Tracking page.
