Source for more mock data

[kwenzig]

If the table ddiadoption_3rd_round.csv from https://doi.org/10.5281/zenodo.15387265 is restricted to all rows with a non‑empty value in the identifier column (last column), many entries turn out to be possible mock data.

An access URL can be constructed using the fields OAIURL, prefix, and identifier as follows:

• CONCATENATE($column:OAIURL;"?verb=GetRecord&identifier=";$column:identifier;"&metadataPrefix=";$column:prefix)
• example: https://api.researchdata.se/oai-pmh?verb=GetRecord&identifier=oai:researchdata.se:2025-197/1&metadataPrefix=ddi25
