The paper gives an overview of the OSCAR system supporting collaborative and distributed authoring of multimedia training materials. OSCAR refers to an application scenario featuring the cooperation of multiple actors and the distribution of the authoring resources such as authors, authoring tools, information base and equipment. Increasing needs of uniformity, quality, productivity and reliability of the courseware development process along with increasing opportunities for large scale training projects are making collaborative and distributed development of training materials one of the most promising sectors of the educational technology market. OSCAR, based on an open system architecture, provides multimedia communication facilities, a common information repository and high level services (co-authoring services) supporting multimedia authoring, collaboration, coordination, co-decision and re-use in courseware projects. In what follows the functionalities and the architecture of OSCAR are described with a special emphasis on the coordination facilities offered by the system. The OSCAR system is being developed within the CEC DELTA Programme.
