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

Why?

IPTC Extension, VRA, and PLUS panels not supported “out of box” Media Bin

Exploring additional EM possibilities will require coding

Why just Core?
