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 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.

Expands the Achievement Standards Network http://zepheira.com/2009/12/jes-co-expands-the-achievement-standards-network/ http://zepheira.com/2009/12/jes-co-expands-the-achievement-standards-network/#comments Mon, 07 Dec 2009 18:38:46 +0000 admin http://wp.zepheira.com/?p=70 At the annual National Science Distributed Learning conference sponsored by the National Science Foundation (NSF), participants learned how JES & Co.’s Achievement Standards Network (ASN) framework is being used by Australia’s Curriculum Corporation in an effort to link educational resource data globally. Zepheira partner David Wood and contractor James Leigh worked with JES to develop a reusable, Open Source editor for Resource Description Framework content as a key portion of this work.

Zepheira combined the JES editor with the Alibaba RDF framework and the Mulgara Semantic Web database to produce a simple and extensible solutions stack for the creation of arbitrary Semantic Web applications. This solutions stack will be released as a new Open Source software project (see Zepheira’s pre-announcement here.

See the full JES & Co. press release for more details on the expansion of the Achievement Standards Network.

Callimachus builds on Mulgara (an established Semantic Web database), Ali Baba (an object-to-RDF mapping technology) and a new generalized, configurable RDF editor. The project will officially launch in December 2009. In the meantime, a slide show is available to preview Callimachus’ features.

Callimachus has been made possible by support from JES & Co., the National Science Foundation and Zepheira.
