Abstract: At present, the need of collaborative development for complex product can not be met by general data integration method. On the basis of analyzing the characteristics of collaborative development for complex product, a new data integration method based on Urid and RDF was proposed. Urid technology was used to solve the distributed and heterogencous problem of data accessing, and RDF technology was used to solve semantic heterogeneity between data sources,and eligible data source was obtained by the selecting approach based on QoS. Finally, an example was given to demonstrate the validity and rationality of the proposed method.
