Abstract:Based on the problem of heterogeneous information among different systems in the field of Ordance Support, and in view of the characteristic of metadata, the thesis raises a solution to resource sharing of Web Service on the basis of metadata. In this thesis, we designed a transitional information format which names SXML, as a bridge of information exchange. JDBC and JDOM are respectively applied to the design of Wrapper and Parser, and the exchange of heterogeneous information was realized finally.
