Great to see these discussions. Glad you found an NMSI photo. Will gladly take credit for that as we were embedding data back when I managed the Science Museum's first major NOF-funded digitisation project in the early 2000s (it included the MMW project).
Sorry to stick my hand up - but embedding metadata is not something one usually gets praise for !
