One of the nice features in the Windows Photo Gallery in Vista is the ability to add hierarchical keywords. I have a few hundred keywords right now. A subset of these keywords are People, Events, Places etc. I would like to collapse the flat list of keywords so I can more easily browse.
Well in the Windows Photo Gallery you can create a keyword like Foo\Bar and it will nest Bar under Foo. Smart, but....
Adobe's newly launched Lightroom has it's own incompatible hierarchal keyword system. When you export a RAW photo, the hierarchy is collapsed and the parent/child relationship is not included.
This whole metadata, xmp, exif stuff is still not interoperable. Annoying. Anyway, here are some pics from our balcony tonight.
