Abstract: In order to solve the problem of “information island" of science and technology resources, the deep integration and application analysis of heterogeneous data is performed. Guided by the application demand of multi perspective users for science and technology resources, the metadata characteristics of multi-source and heterogeneous science and technology resources are analyzed, and the integration design of heterogeneous data is carried out by using association aggregation method and knowledge organization tool to establish the relationship between various types of science and technology resources. Based on the application of science and technology resources metadata of information service platform of Jilin Province science and technology literature (referred to as “the platform"), the metadata storage and sharing service of multi-source heterogeneous data of the platform is realized, and the degree and effect of science and technology resources sharing service are enhanced.
