Hello Kirk,
After googling around it does indeed seem that Lightroom uses sublocation instead of location, and there is no sub-location field, but this is still all very new to me and I am just trying to sort out a catloging system that integrates PM and LR, while at the same time learning to use both.
In fact the PM hierarchy suits me better as I can put UK counties into the PM location field, but that sort of falls apart when imported into LR, with the hirearchical metadata sort facility that LR has.
Is there is no standard for the hierarchy of these fields. Everything I have found seems to the same as Lightroom, with PM the one that is different, but I'm not sure whather this is an IPTC standard, or it just so happens everything I have found is Adobe based.
Actually, it seems that location from iptc 1.0 was replaced with sublocation in iptc 1.1, so Lightroom is using the more up to date terminology.
Cheers,
Graham
