How do I get "work" tags?

[InvisibleFunction]

I use LMS which just added support for files tagged with work. I looked at my files and I don't seem to have that tag, though a number do have "mb_workid"/"MUSICBRAINZ_WORKID". How do I get things tagged with "work"?

me@compy:/Volumes/Music/Music$ beet info -l The\ Milk\ Carton\ Kids/Christmas\ In\ A\ Minor\ Key/01\ The\ First\ Noel.flac  | grep -i work
          mb_parentworkid: 78bb65b9-29a1-414e-a503-673894d636a3
                mb_workid: 631091d0-feb9-4edd-ac43-95ab24b3bc23
               parentwork: Meet Me in St. Louis
      parentwork_disambig: 1944 film
parentwork_workid_current: 631091d0-feb9-4edd-ac43-95ab24b3bc23
                     work: The First Noël
            work_disambig:
me@compy:/Volumes/Music/Music$ beet info The\ Milk\ Carton\ Kids/Christmas\ In\ A\ Minor\ Key/01\ The\ First\ Noel.flac  | grep -i work
           mb_workid: 631091d0-feb9-4edd-ac43-95ab24b3bc23
me@compy:/Volumes/Music/Music$ metaflac --list The\ Milk\ Carton\ Kids/Christmas\ In\ A\ Minor\ Key/01\ The\ First\ Noel.flac | grep -i work

It looks like the info is in the db, but is not written to the files?

EDIT: I think I need to extend https://github.com/beetbox/mediafile , is that right?

I'd also be interested in this. Furthermore it would be really nice to be able to write the parentwork information into the work tag. I patched mediafile locally and successfully wrote the work tag. If someone could provide some idea on how to implement this I could try to do it.
