Content and Context: Two Worlds to Bridge

Networks, terminals and users are becoming increasingly heterogeneous. In this context, the growing availability and usage of multimedia content have been raising the relevance of content adaptation technologies able to fulfill the needs associated to all usage conditions without multiplying the number of versions available for the same piece of content. For efficient and effective adaptations, content and context descriptions must be available in order these two worlds are adequately bridged. This paper discusses the problem of content adaptation considering the major technologies which may have a role to play in achieving the ‘one fits all’ content provision paradigm with emphasis on descriptions/metadata.
