That would appear to be a custom column. So I guess your question is really "how can I manipulate calibre custom columns using ebook-meta?"

Answer: I don't think you can, because custom columns need the database to define what data type they are.
You could kludge something together --from-opf of course...

FWIW, `calibredb set_metadata` can set custom columns in the database, and `calibredb embed_metadata` can embed them into the ebook files.
