NATIONAL DIGITAL PRESERVATION SERVICES

Digital preservation refers to the reliable preservation of digital information for several decades or even centuries. Hardware, software, and file formats will become outdated, while the information must be preserved. Reliable digital preservation requires active monitoring of information integrity and anticipation of various risks. Metadata, which describes for example the information content, provenance information and how the content can be used, has a key role in this.

The Digital Preservation Service (DPS) produced for cultural heritage resources, guarantees the preservation of essential national information resources held in libraries, archives and museums. Digital cultural heritage resources cover both digitised and born-digital information resources: publications falling within the bounds of legal deposit, government publications belonging to the national cultural heritage, and other digital information resources worth preserving created by organisations operating under the Ministry of Education and Culture.

The DPS produced for research data ensures the availability and preservation of digital research resources. This DPS supports a permanent and coordinated approach to support the management of research resources. The aim is to ensure the verifiability and repeatability of research at various stages of the life cycle and to make the results easy to use. This enables that research results can be reused, evaluated, utilized in decision-making and secured by increasing digit data for future generations of researchers.

Updated versions of our national specifications published

Updated versions of our national digital preservation specifications have been published:

DPX validator published

We have recently released a lightweight DPX validator, see: https://github.com/Digital-Preservation-Finland/dpx-validator.

Our aim is to use an efficient way to check that the file most likely is an unbroken DPX file. To make the validation fast enough for fully automated processes, our validator just validates five elements from the DPX header. See details from the README file in Github. Our DPX validation tool is currently in use in the ingest validation in our digital preservation services.

METS validator published

National digital preservation services (DP services) has released a METS Validation Tool. METS (Metadata Encoding and Transfer Standard) is a metadata encoding and transfer standard that transfers data to DP service and from DP service.

The new tool can help to ensure that METS documents sent to the DP service compliant with the national specification. The tool is specifically intended for future users of the DP service, but anyone can use it.
