Hi Paul - thanks for the report. We''ll check this out.  Looks like an XML parsing error.

Product: mod-rdf-jena
Version: 0.9.1

We are pleased to announce the availability of an RDF library module for NetKernel. The library provides a toolset for working with RDF models. It consists of utility services for parsing and serializing the RDF serializations including XML/RDF, N3 and N-Triple syntax. Once parsed the RDF models are represented as Jena Models and with a NetKernel resource aspect IAspectJenaModel. A range of tools are provided for manipulating models - these are divided into Set operations and Query/update operations.

Installation

1. Select "Install new applications and libraries" in the module install wizard - http://localhost:1060/ep+name@app_install_installer
2. Select your prefered mirror site and check the box marked "Display libraries".
3. Select checkbox marked "RDF Library based on Jena"
4. Follow onscreen prompts to complete installation.
5. Once NetKernel has hot-restarted search the documentation for "rdf" for guides and reference docs.

Installation Troubleshooting:  mod-rdf-jena is quite large (6MB), if you have a slow internet connection you may find that the installation times-out before the download is complete.  To prevent this timeout, temporarily increase the kernel''s deadlock detection period to a large value using the kernel config tool - http://localhost:1060/ep+name@app_ext_introspect_sysconfig

The library was only posted within the last hour - if you cannot see the RDF module on your chosen mirror then it has not yet been mirrored (this can take up to 24hrs) - in the mean time try the 1060 Primary Mirror.

Acknowledgements

Our thanks go to the Los Alamos National Laboratories Digital Library team for support and feedback whilst developing this library. Thanks also to our former colleagues in the HP Semantic Web team for their work in developing the Jena library.

Feedback

As ever, we welcome your feedback, please send comments to feedback@1060.org. or via this forum.

All the best,
