Updated versions of our national digital preservation specifications have been 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.
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.
