By carefully analysis OWS and its relevant interoperability specification, author found that OWS based on geospatial interoperability application is confronted with embarrass of incapability of sharing again, because current framework of OWS lacks of integrative "conglutination" mechanism, precise geospatial oriented interoperability specification and its incompatibility with traditional interoperability specification. On the basis of GML (Geography Markup Language, GML), this paper proposes improved OWS interoperability model-OGIF (OWS based GML spatial Interoperability Framework) and creates operation architecture structure which can obviously improve geospatial and geography problem orientated interaction semantic expression mechanism; designs technology architecture consisted of client application component aggregation, Web application service aggregation, GML application service aggregation, registry service aggregation and data storage service aggregation; Microsoft .NET and private UDDI based constructs system architecture.
