Integration of distributed educational library resources based on metadata and web service middleware

After analysis of the current situation of educational library resources construction,an integration scheme of distributed heterogeneous educational library resources(DHELR) based on uniform management of metadata and web service middleware is brought forward.Meanwhile,nine function modules and their working models are designed for the web service middleware which is used for DHELR's connection and operation.The scheme can solve some problems,which are how to share educational resource in DHELR,how to reuse old educational resource library system,how to protect the investment and how to provide users with a transparent,onestop-visit environment.
