The State and University Library (hereafter called SB) is a public institution under the Danish Ministry of Culture. The library serves as university library for Aarhus University, as the main loan centre for Danish public libraries and also as a national library.

As a national library SB is engaged in long term preservation of digital cultural heritage material as part of its obligations according to the Danish legal deposit law.

SB wants to procure a new System, that shall replace the Existing Metadata Repository and the Metadata Management GUI in the existing Infrastructure for Digital Preservation. At the same time we expect the new system to fully or partially replace our components for ingest and analysis, enrichment and validation processes, metadata export, and access copy generation. Furthermore, we expect the new System to help us expand our processes for Digital Preservation Planning and Digital Preservation Actions.

The State and University Library (hereafter called SB) is a public institution under the Danish Ministry of Culture. The library serves as university library for Aarhus University, as the main loan centre for Danish public libraries and also as a national library.

As a national library SB is engaged in long term preservation of digital cultural heritage material as part of its obligations according to the Danish legal deposit law. Besides many audio collections SB also holds the Danish National Radio and TV Archive which includes more than 2.7 PB of digital recordings and grows daily. Another large collection is the digital newspaper collection with more than 26 000 000 digitised newspaper pages. This collection also grows daily and will hold close to 30 000 000 newspaper pages by the end of 2016.

All digital collections are to be preserved in the Digital Repository according to the core principles of the OAIS Reference Model (ISO 14721).

Our Existing Metadata Repository is open source, developed in-house and based on Fedora 3. One of the major problems of the Existing Metadata Repository is its inability to scale as the collections grow. We carry out the preservation of many millions of objects and we anticipate a large growth in the years to come. The new System must be able to scale to billions of objects and to integrate with SB's existing bit preservation solution, the Bit Repository.
