Digital Rights Management for Distributed Multimedia E- Learning Content

Nowadays a steadily increasing amount of multimedia content is generated and requires storage in digital libraries. Current research focuses on identifying user needs to make relevant information available through semantically enhanced retrieval techniques. In this context the already complex task of retrieving multimedia content on a semantic level is further complicated by right management and security issues which are evolving into fundamental topics in the area of digital libraries. Previous research conducted by our group concentrated on topics like extraction of metadata from multimedia content, indexing of metadata and application of indexed metadata for storage, search and retrieval tasks. Our research activities resulted in a semantic technology framework for metadata based multimedia retrieval. Based on these results we have selected promising and emerging technologies to extend our framework according to the application domain E-Learning with special focus on digital rights management in context of distributed multimedia learning content management systems.
