PMID not imported

Problem/Motivation

I also posted this problem under the main BibCite module, but realized that this might be a more appropriate place for it.

I am migrating an old Drupal 7 website that uses the Biblio module and need to import a large database of Biblio Content Items that use the PMID field. Even after configuring PMID > PMID on the settings page /admin/config/bibcite/settings/mapping/csl, the PMID field is not imported. The field is left blank.

Steps to reproduce

Configure PMID > PMID on the settings page /admin/config/bibcite/settings/mapping/csl and then import the source data via dashboard at /upgrade

Proposed resolution

Judging from the code files in src / Plugin / migrate / source, and the YML files under /migrate I'm guessing that something else needs to be written to pull in this data from the biblio_pubmed table, but I have no clear idea how this would be done.

Remaining tasks

User interface changes

API changes

Data model changes
