Ann: Marbles 1.0 released on SourceForge

Hi all,
I'm pleased to announce the release of Marbles on SourceForge at http://marbles.sourceforge.net/ 
.

 From the Marbles documentation:

Marbles is a server-side application that formats Semantic Web content  
for XHTML clients using Fresnel lenses and formats. Colored dots are  
used to correlate the origin of displayed data with a list of data  
sources, hence the name.
By performing all formatting, data retrieval and storage activities on  
the server side rather than on a potentially thinly equipped client,  
the view generation can touch on large amounts of data and requests  
can be answered relatively quickly. Marbles provides display and  
database capabilities for DBpedia Mobile.

Data is retrieved from multiple sources and integrated into a single  
graph that is persisted across user sessions. When provided with the  
URI of a resource to display, Marbles tries to dereference it. In  
parallel, it queries Sindice for datasources that contain information  
about the given resource, and Revyu for reviews. In a similar manner  
as the Semantic Web Client Library, Marbles follows specific  
predicates found in retrieved data such as owl:sameAs and rdfs:seeAlso  
in order to gain more information about a resource and to obtain human- 
friendly resource labels.

Marbles uses the following components:

     * Sesame 2.1 with MySQL Storage for the browser's data model and  
storage of cached data; tweaked to support inference
     * SIMILE Fresnel Engine and IsaViz FSL; both were tweaked to  
support provenance and performant access to large graphs.
     * SAXON XSLT and XQuery Processor to generate XHTML  
representations of the rendered Fresnel trees
     * The dereferencer is partially based on the Semantic Web Client  
Library and makes use of the Apache Commons HTTP Client for optimized  
retrieval

We have also set up a new public server on http://www5.wiwiss.fu-berlin.de/marbles/

Thanks to Eli Lilly and Company for supporting the open-sourcing of  
Marbles in part by a research grant.

Cheers,

Christian
