Thanks for the replies (and to the split-off discussion with Reinhold and Simon)
Minjie, FRBR Document 3.3 is just what I'm talking about, at least in regards to FRBR. Looking for a
similar solution in BIBFRAME is where I am at the moment.
With regards to the conceptuality level of a 'Work', I understand that BIBFRAME's has less of a 'sky is
the limit' view than FRBR, which is a good thing in my opinion. Going back to my One Piece example,
in FRBR the Work level for One Piece could act as an umbrella entity for the manga, TV series, etc., but
in BIBFRAME this overall conceptual level is not necessarily present, with connections between
resources being made with relationships instead.
I think the core issue in the manga case is how resource specific should the BIBFRAME Work level
represent. Perhaps the 'right' answer may depend on an institutions resources and their cataloguing
practices. If a library is collecting an entire complete manga series and cataloguing it as such rather
than individual volumes, then I think having the series act as a Work with each volume being an
Instance is the logical conclusion. BIBFRAME certainly would allow each volume to be represented as a
Work, with relationships being made between each one, but I don't know if this is a better solution
(both conceptually and practically with regards to cataloguing practices.)
