Querying: Xcerpt - a versatile rule-based Web query language; and the CIQCAG query algebra - a highly scalable evaluation for Xcerpt and other Web query languages (http://queryware.com ).

Evolution and Reactivity: The prototype r3 (Resourceful Reactive Rules) - a general Semantic Web rule engine for reactive rules ( http://rewerse.net/I5/r3 ); the event query language XChangeEQ - a declarative high-level reactivity language (http://rewerse.net/I5 ).


Regarding advanced Web applications REWERSE has realized the following main systems:


Time and Location: The CTTN system for the treatment of geotemporal the CTSN system for geospatial notions is available. Additionally, the EFGT Net with concepts and named entities is ready for commercial exploitation (TopicZoom GmbH) ( http://rewerse.net/A1 ).

Bioinformatics: REWERSE has shown that the Semantic Web for life sciences is a reality by providing novel reasoning based solutions, e.g. the award winning GoPubMed.org, an ontology based literature search engine and further applications ( http://rewerse.net/A2 and http://transinsight.com ).

Personalization: REWERSE has developed the Personal Reader Framework, a complete suite of personalization services with several award winning applications ( http://www.personal-reader.de/rewerse ).
