47. kcoyle@kcoyle.net Some issues - FRBR Not well understood Untested, mostly unimplemented Superceded by FRAD, FRSAD, and now requiring changes to be compatible Group 1 (WEMI) may impede interaction with non-FRBR-ized metadata.

48. kcoyle@kcoyle.net More issues - FRBR Group 3 (Subjects) should be replaced with a general subject relationship to anything that can be identified Group 3 elements should be general (e.g. Place) or be subproperties of a more general property Placement of data elements within WEMI is highly debated, especially for collective items (books of essays, multiple music works on a disk).
