I am a researcher at University of Vienna, Department of Distributed and Multimedia Systems and co-founder and CTO of Gnowsis.com, designing and developing Cluug, a tool to help people remember. I am working in the field of Semantic Web, Semantic Desktop, and integration of semantic information into file systems. I wrote my doctoral thesis about infrastructures for Semantic Desktop applications.
Currently we are running (amongst others) the SemDAV project (semantic enrichment of personal and corporate document collections) and the MobiSem project (availability of RDF data on mobile devices); if you are interested get in touch with me.
