As users’ requirements for information integration enhance increasingly, how to integrate multiply heterogeneous data in a global sharing system has especially been a challenge for its large scale and diverse formats. To address the above problem, this paper proposes an information sharing approach for multiply heterogeneous data based on a two-layer metadata. Firstly, the architecture of the two-layer metadata is introduced. Secondly, the synchronization between different users for distributed heterogeneous data is realized by sharing table structures. Finally, Lucene search engine combined with the element GM-description of the two-layer metadata is presented to retrieve metadata, which reduces the response time compared to other retrieval methods. The experiment results illustrate the effectiveness of our approach and the conclusion is given.
