The PURL Open Source Software community site at purlz.org has been migrated from Zepheira’s servers to Google Code.  Accordingly, the mailing lists hosted at purlz.org are also migrating to a Google Group.
The purlz.org DNS domain will redirect to the Google Code site.  The new Google Group that replaces the mailing lists is:  http://groups.google.com/group/persistenturls. Please subscribe!
Thanks for your patience and support as we transition the community infrastructure.  We look forward to continuing to serve you and the PURL community.

Zepheira will be presenting two papers at the W3C RDF Next Step Workshop on the future of RDF on June 26-27, 2010. The goal of the workshop is to gather feedback from the Semantic Web community on whether and in which direction RDF should evolve.

Zepheira will present a new RESTful RDF Store API supporting named queries and change isolation. Zepheira will also propose alternative handling of rdf:List in SPARQL. For more information on the workshop and to review the papers look here.

Callimachus is a Semantic Web framework for easily building hyperlinked Web applications. Callimachus allows Web authors to quickly and easily create Semantically-enabled Web applications with a minimal knowledge of Semantic Web principles or experience building other Web applications. Callimachus uses RDFa as both a query language and display template to make it quick and easy to create your own metadata management tools.

For more information about Callimachus visit the project page at http://callimachusproject.org
