Coordination of data in heterogenous domains

摘要

Existing semantic integration approaches to coordinating data do not meet the needs of real world scenarios which contain fine-grained relationships between data sources. In this paper, we describe extensions to the popular GLAV mapping formalism to express such relationships. We outline methods for solving the data coordination problem using these mappings, and discuss future research problems for data coordination to be realized in heterogeneous domain scenarios that occur in practice.
