A semantic-based information integration scheme for MedImGrid (medical image grid) is presented, which creates parent-ontology (HL7-RIM ontology) based on HL7-RIM (health level 7 referenced information model), and adopts hybrid means to construct the hierarchical structure of MedImGrid global and local ontologies. The HL7 (health level 7) gird middleware is developed based on Agent and middleware technology, which gives the semantic parsing capability to HL7 intelligent Agent to support grid service encapsulation and uniform access of heterogeneous data sources. The interrelations of data modes at ontology layer are denoted with ontology tag and used to support the semantic parsing and mapping between different medical data sources referring to MedImGrid ontologies. MedImGrid prototype is based on CGSP2 (China grid support platform v2.0) and adopts global and local semantic mapping loosely coupled means, and its special layered structure makes resource sharing and matching across systems and hospitals more efficient.

“…OGSA-DAI is the middleware to access and integration data from different databases by grid based on Globus platform, which provides users with uniform service interface and shares in data and cooperate with handling. OGSA-DAI has shielded heterogeneous data in storage management, however, this has no solution to heterogeneity for information representation [5] . The paper has proposed a data integration model based on OGSA-DAI and expand its functions, which adopted distributed query technology, finally realized data transparent access and associated query.…”

Aiming at the existing problems with traditional integration technology, the system structure, service and workflow of OGSA-DAI are analyzed thoroughly. Based on OGSA-DAI extension, the data heterogeneity of semantic is shielded by schema mapping. An integration model is proposed to solve data integration and distributed query under the grid environment, achieving transparent access to distributed heterogeneous data and associated process.
