Currently we are evaluating different approaches to distribute and query XML data. Basically, we are interested in using such an approach directly out of XQuery. The complexity for XQuery developers should be as small as possible, therefore we prefer solutions which do not extend XQuery specification with complex hierarchical structures. The "Distributed XQuery-based integration and visualization of multimodality brain mapping data" approach looks interesting and straightforward. We do more research in distribution approaches within the next weeks. > > regards > Lukas > > > On Monday, November 14, 2011 17:32 CET, Christian Grün <christian.gruen at uni-konstanz.de> wrote: > > > Hi Eric, > > > > nice to have your update! > > > > > I've been seeing quite a bit of chatter about cloud computing and > > > distributed systems at work of recent.
