A system for semantic retrieval and long-term preservation of multimedia documents in the e-government domain

In this work we propose a new model for Multimedia documents, Suitable for e-government applications, that provides different representations of the same Multimedia contents, allowing to solve open problems related to the technology evolution, different documental format and access rights. The model constitutes the starting point for an information system capable of managing documental streams integrating and processing different Multimedia data types and providing facilities for indexing, storage and retrieval, together with long-term preservation strategies. We have implemented a prototypal version of file system that realises the described Information Retrieval and Presentation tasks for juridical documents.
