National Agricultural Research Information Management System (NARIMS) aims to enable agriculture scientists to carry out researches more effectively. It preserves existing information resources, prevent redundancy and duplication, and helps increasing co-ordination among researches. In order to maximize collaboration and the use of NARIMS in Egypt and similar Information systems in other regional countries, Open Archives Initiative Protocol (OAI) for Metadata Harvesting of NARIMS publications has been implemented in CLAES.OAI provides an application-independent interoperability framework based on metadata harvesting
