A Workflow Model and Architecture for Content and Metadata Management Based on Grid Computing

Large scale multimedia services such as social networks, content delivery networks, online service archives provide access to huge amount of content with several hundreds of descriptors fields associated with and file versions, thus really complex content management systems. They have a great need of and orchestrated workflow system and automated process management system that allow managing content and metadata, in order to automate as much as possible the activities (thus reducing the costs) and increasing the quality and accessibility. Grid computing technology may aid at integrating and improving existing content management and workflow systems in order to efficiently organize and manage large amount of data and processes to cope with them. In this context, the workflow model and architecture base on grid computing adopted by ECLAP network is presented.
