System Architecture

• Built upon robust, flexible and well documented frameworks and technologies:

– Apache Tomcat 6.0

– Spring Framework 3.0.5

– Spring Security 3.0.3

– ExtJS 3.3.1

• Using SKOS (RDF) as metadata format – standardized by the W3C

technologies

Indexing and Mapping

• Rich metadata in a standardized, extensible format (SKOS / RDF)

• Central metadata repository
