Hi Mario, What you're talking about is similar to what I'd call an Asset
Type metadata concept and it's pretty common--our clients would very
commonly have a tag structure under an Asset Type namespace that would
include several types of photography (e.g. lifestyle, product, executive
headshots), collateral (e.g. brochures, sales sheets, white papers),
advertisements (e.g. banner ads), and so forth. Your focus on the
appropriate distribution channel is another concept that is less
commonly used,...
