I'm pleased to announce the first official release of LENA [1], a Fresnel Lens based RDF Navigator with SPARQL selector support.
[1] http://isweb.uni-koblenz.de/Research/lena A demo is available here: http://dom.uni-koblenz.de:8080/lena LENA stands for LEns based NAvigator. A lens represents a particular view onto RDF data and is described by the Fresnel Display Vocabulary [2]. LENA enables viewing RDF data in your web browser, rendered according to the lens descriptions you provide. LENA supports the use of multiple lenses and indicates if they are available for a resource, so that a different view onto the same data is always just one click away! To write lenses for complex RDF structures, LENA supports SPARQL selectors. While SPARQL [3] is a designated Fresnel selector language, an implementation did not yet exist. LENA provides an extension to support Fresnel SPARQL selectors that is now integrated into the Simile Fresnel engine [4]. The data which shall be processed by LENA, can either be put into the provided directory or be accessed through a Sesame [5] HTTP repository. For more information about the usage of LENA see the project page [1].
