Kevin,

Thanks for setting this up. Drilling down into the explanations of
Work and Types of Work I can see that in BibFrame Works are Resources,
and therefore can have the properties of Resources as well as
properties specific to Works, and that Types of Work (examples:
Dissertation, Cartographic) include more specific properties as well,
in addition to the properties of Resource and Work.

Could the Types of Work be defined on a different level--less format,
more FRBR? Could FRBR Work and FRBR Expression be types of the
BibFrame Work, with the latter taking over the Language property, or
must all BibFrame Works include the property Language, regardless of
type? Could Integral Work and Aggregated Work (another distinction
from FRBR) be defined in BibFrame as Types of Work? The use case for
the latter would be, say, to differentiate by type between a BibFrame
Work description of Hamlet the play (a FRBR integral work) and a
BibFrame Work description of a critical edition of Hamlet (a FRBR
aggregated work)--to provide different answers to the questions "What
did Shakespeare write?" and "What does the library have by
Shakespeare?"

Are these the sort of things that an RDA profile for BibFrame could
specify? Are these useful questions to be raising?
