I am currently trying to improve the visibility of our Items in Google Scholar. So I had a look at the documentation and the mapping file and found a potential problem:
Google expects the publication date tag, e.g., citation_publication_date ... Don't use it for the date of entry into the repository - that should go into citation_online_date instead.
But the DSpace mapping file (google-metadata.properties) does this:
google.citation_date = dc.date.copyright | dc.date.issued | dc.date.available | dc.date.accessioned
Is this a wrong mapping or did I miss something?
Thanks in advance
You are correct, citation_publication_date should use the date the publication was published. Only for some ways of online publishing, where the repository is the only source of the published item, the date of entry in the repository and the citation_publication_date would correspond.
Depending on which metadata fields you use in the repository, it is highly recommended to customize the configuration for the mapping.
