SIARD (Software Independent Archiving of Relational Databases) software has been developed by Planets Consortium partner, the Swiss Federal Archives, and enhanced within the Planets project.
The SIARD suite consists of an open storage format for relational databases based on international standards (SQL 1999 and XML) and a software tool to support long-term archiving of database content.
This open storage format makes it possible to retain the content, relationships and metadata of relational databases. The software tool makes it possible to convert relational databases into SIARD, archive and upload them into a database instance, when required.
Planets has adopted SIARD as its official format for preservation of relational databases.
