use of additional identifiers to determine duplicates

[pvgenuchten]

Resources can be identified by multiple identifiers:

• DOI (with http/https, without prefix, ...) (https://doi.org/10.18174/651649)
• The url where DOI resolves to (https://zenodo.org/records/12743276)
• If DOI resolves to a metadata page, the link to the actual download location (https://edepot.wur.nl/651649)

Soilwise should store these alternative identifiers as part of the resource, so when any of the identifiers is found, a reference to this resource can be established
