The project HSM addresses serveral research questions regarding problems of document archiving and long term archiving of various multimedia formats. For example, this concerns the software architecture, interfaces and management algorithms, different document formats for long time archiving (also interactive documents), questions regarding the digital rights management of specific information, aspects of data security, cryptography and key management, but also research questions about metadata management and extraction of semantic data of documents, as also problems of the usability of client- and serversided applications.
