The centralized National Digital Preservation Services provide open and cost-effective digital storage for cultural heritage organizations and higher education and research institutions under the Ministry of Education and Culture. The Digital Preservation Services keep the organizations' content fixed, authentic and usable. Digital preservation is an active activity from which the use of a Digital Preservation Service frees the organization to focus on its core activities.
Updated versions of our national digital preservation specifications have been published:
- Metadata Requirements and Preparing Content for Digital Preservation (v1.7.2), defines how content is transferred to the preservation service and what metadata it should contain.
- File Formats (v1.8.0), describes the file formats acceptable in our preservation service.
- Service Interfaces (v2.1.1), defines the machine readable interfaces of our preservation service.
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.
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.
