I am trying myself on a metadata download plugin (to download DOI data from Crossref). I followed the documentation and the source of the GoogleBooks importer and had quick successes. Currently I'm able to download and parse the metadata and store into calibre default fields. However these articles contain data that doesn't fit into the calibre fields and I want to a custom column to hold them.

Unfortunately, I got stuck and really could use some guidance how to achieve this.

The most promising approach was to use the `set_user_metadata` function while I construct the Metadata object. The data I wanted to store was correctly shown in the log. However it did not get persisted. Could anyone give an example with the correct syntax?
