I’m planning on adding many of Big Finish’s releases into MusicBrainz, but even after discussing this on the IRC channel, I’m not sure just creating a release group and one release per ISBN is the best.
Let’s take for example: https://www.bigfinish.com/releases/v/doctor-who-embrace-the-darkness-2
It has nicely listed the voice cast:
Paul McGann (The Doctor) India Fisher (Charley) Nicola Boyce (Orliensa) Ian Brooker (ROSM) Mark McDonnell (Hallard) Lee Moone (Ferras)
And also the production crew:
Cover Artist Clayton Hickman Director Nicholas Briggs Executive Producer Jacqueline Rayner Music Jim Mortimore Producer Gary Russell Jason Haigh-Ellery Sound Design Jim Mortimore Written by Nicholas Briggs
Also the format information (there’s also a digital release for this one given the download button, but that doesn’t have an ISBN):
Product Format: 2-disc CD (jewel case) Number of Discs: 2 Duration: 125 minutes Physical Retail ISBN: 1-903654-60-2 Production Code: BFPDWCD8J
Now, adding all the production crew to the release would be possible, but people like the writer or format creator would suit a work more. And there are a few other minor things that irk me a bit (“director” not existing as a relationship for ex.)
So the question in the end is, given the data on the page, what data types (release, release group, recording, work etc.) should I use and what information should each contain to enter as much data as neatly as possible?
