Title: Data Sharing and Exchange: General Data-Mapping Semantics.

Abstract:

Several settings have been introduced in the literature to solve the problem of integrating data  from different applications that use different vocabularies. Those include data coordination settings, and recently, data sharing and exchange settings. Data coordination allows integrating information from different sources with different domains at query time. Data sharing and exchange on the other hand exchanges information between applications that maintain same objects using different names. We discuss in this paper a more general data sharing and exchange setting which exchanges information between applications that store related   information that is not necessarily equivalent.
