Persistent TestBed Federated Access Management for research & teaching in the SDI Saxony (GeoSN, TU Dresden, con terra; 9/2012-12/2013) http://sdi-testbed.eu Main Goals: Combine SDI access management with the German research network (http://www.dfn.de) Enabling researchers and students to get access to the SDI in a single-sign-on-manner (similar to accessing digital libraries) Appropriate license model to allow for research and teaching use based on existing licensing frameworks 23 TU Dresden Scientific GDI
Using (volunteered) crowd soucing!? Issues When & where do we reach the critical size of the crowd, esp. for volunteered crowd sourcing? Quality control, esp. for spatiotemporal phenomena (includes modeling trust) Data fusion & data mining (derive relevant events/processes) Data privacy TU Dresden Scientific GDI http://watch.eyeonearth.org 24
Conclusions As GDI get established in Administrations Scientific GDI are still in their infancies and have several challenging questions for us... Scientific GDI are more than GDI...(here we focussed functional aspects, but did not cover archiving, funding, operation, etc.) need more elaboration an horizontal measures & activities Scientific GDI should become part of Research Infrastructures (NSF Earth Cube, ESFRI Environment...)
