DigitalPreservationEurope has released Database Preservation: The International Challenge and the Swiss Solution.
Here's the abstract:
Most administrative records are stored in databases. Today’s challenge is preserving the information and making it accessible for years to come, ensuring knowledge-transfer as well as administrative sustainability. Lack of standardization has hitherto rendered the task of archiving database content highly complex. The Swiss Federal Archives have developed a new XML based format which permits long-term preservation of the relational databases content. The Software-Independent Archiving of Relational Databases (short: SIARD) offers a unique solution for preserving data content, metadata as well as the relations in an ISO conform format.
