DYNAMIC collection, “Art In Bloom”
Well documented, incorporated into most photo tools
Great guidelines, user support; frequently and consistently updated
Widespread cross-disciplinary use
Currently supported in Media Bin database

IPTC Extension, VRA, and PLUS panels not supported “out of box” Media Bin
Exploring additional EM possibilities will require coding
Why just Core?
