Custom columns to call up metadata from epub's opf?
I have a collection of epubs that include both author (<dc:creator opf:role="aut">) and artist (<dc:creator opf:role="art">) information in the opf. The author information displays just fine, but I think I need to create a column to display the artists. I'd rather not have to add this information from scratch. Is there any way to create a column that will read this information if it exists in the epub...?

No. Custom columns can read only the info in calibre's database for the book.
One way to get started would be to use the command line. Write a script/program that scans your library for epubs, extracts the OPF from the epub, extracts the artist information from that opf, then writes that information to a custom column using calibredb set_custom. The library scan could use a search to look for books that have not been processed, perhaps a tag or perhaps a boolean custom column.
