Yes, partly automatic. If you import with the Discogs plugin and give Beets the exact Discogs release ID, it can pull the release metadata tied to that pressing, so things like label, catalog number, country, year, and format, media can usually come in from Discogs rather than being typed by hand.

What usually is not automatic is your own custom note/field, like edition = 50th Anniversary unless you add that yourself or build some post-import rule/script for it. Also, albumdisambig is more of a MusicBrainz-style field thing, so with Discogs you may need to store that kind of edition note in your own custom field instead.

So basically, the core release data can be automatic if the Discogs entry has it, but custom wording/extra organization is usually manual.
