However, all of these tools have the same requirement: they operate on plain text encoded metadata which may become a burden especially in constrained and streaming environments, e.g., when metadata needs to be processed together with multimedia content which is available in a highly efficient, binary representation format. In this paper we present techniques for transforming such kind of metadata which is encoded using the well known MPEG-7 Systems Binary Format for Metadata (BiM) without additional en-/decoding overheads, i.e., within the binary domain. As such it enables us to process both the multimedia data as well as the metadata within its compressed domain, e.g., for metadata-driven adaptation purposes within intermediary network nodes which are becoming increasingly popular in the multimedia community as well as in the XML community.}, issn = {952-15-1364-0}, language = {EN}, pdf = {https://www.itec.aau.at/bib/files/TR_TransformingMPEG-21genericBitstreamSyntaxDescriptionsWithinTheBinaryDomain_Jun2005.pdf}, talktype = {none} }
