Interoperability of Digitizing Systems Based on Semantic Grid

With the growth of the complex multi-disciplinary collaborative design product demand, the collaborative environment and functionality interoperability of the product design put forward higher requirements. To solve the issues of information-sharing among heterogeneous digitizing systems, this paper introduces semantic grid combined by semantic Web and grid technology, and proposes the semantic grid hierarchy model supporting interoperability, and establishes digital system interoperability integration framework based on semantic grid, and achieves a prototype system on this basis.
