Our research themes•An information value chain of producers & con-sumers yields an assured information sharing lifecycle

• PoliciesPolicies for trust, access and use grounded in sharable semantic models operating in a service oriented architecture accelerate sharing

•New integration integration andand discovery discovery techniques are required to assure information quality and privacy

•Modeling, analyzing and exploiting social social networksnetworks and incentives for sharing
