Hello, So I've come across this thread online about mods:coordinates. And now I'm seeing an incompatable case while attempting to map DCMI Box to MODS. Apparently, DCMI Box is defined to be a Bounding Box (or Window) representing a rectangular area on a map. http://dublincore.org/documents/dcmi-box/ Since mods:coordinates are "points" one cannot use them easily to produce a bounding box without having to also convert from points to sides (and vis versa). My question, is there any way to represent the sides of a bounding box (not the corners of a polygon) in MODS? thanks, Mark ~~~~~~~~~~~~~ Mark R.
