Based on the model of Open Archival Information System (OAIS) and the Directory of Open Access Journals (DOAJ), this study designs and implements an information system for integrating directories of open access (OA) journals. The issues examined in the study include metadata formats, dissemination of information package, method of connecting systems across different platforms, and communication protocols. The proposed system would benefit the system developer in designing and developing OA systems on the web which could be connected to the DOAJ platform with ease. Sharing and using of OA journals would thus be greatly increased as a result. The online system of the Journal of Educational Media and Library Sciences (JoEMLS) is used in the study as the environment for implementing the proposed model, originating and modifying from the OAIS. By analyzing the four main user types of JoEMLS system, we develop four distinct subsystems for ingesting, archiving, managing, and accessing JoEMLS. The result of the research project is that the integrated system can not only work successfully with the original JoEMLS system but also can be connected to the platform of DOAJ seamlessly.
