What happened to the Lightroom Export XMP options in LR3?

I can't find them anywhere? It's been a while, but there definitely was such a function in LR2 or LR1.

If your metadata is embedded in the PSD or JPG files, how do you extract them now?

Is there no longer a catalogue preference to save the changes as XMP?

This link is from the LR 3 Beta and it appears there is still an option to do that.

If you normally have the XMP information written to the original file, there used to be an option to export the XMP for the selected files.

In fact, I had my LR set to write XMP info into PSD and JPG files, but not RAW files. Normally, I see XMP files for my RAW files just fine.

But turning this off doesn't seem to make any difference for JPEG and PSD files! I still don't see XMP files, except for my RAW files. And when I tell it to save metadata, it saves it to the file still.

WTF?

Certain file types will store the meta data INSIDE the file (JPG, TIFF & DNG... probably others dunno). RAW files create the sidecar files.

Another bug that is REALLY annoying for this is if you export with a date in the file name the ^&%&% name keeps changing since it uses the windows date for the export and that changes every time you save the metadata.

It does look like there's no way anymore to write XMP data for a JPEG file. I'm guessing the "Include development settings inside JPEG, TIF, and PSD files" option switches between writing them in the file, or writing them to the CATALOG, not XMP files.

I think it was back in version 1 that you could use XMP with JPEG; I recall that I had to turn that on because Finder and a number of other utilities on the Mac were crashing when they saw certain LR metadata in JPEGs, due to a bug in the OS that was eventually fixed (but not quickly enough!)

Anyway, I think there should be a way to export the develop data into XMP files still. For one thing, it can help you send in your settings for a validation (which is how I got here today!)

By the way of bugs/design flaws: the problem with writing metadata back to the file itself is serious; despite the fact the many LR books and pundits push DNG because the RAW files can then be stored with settings and no sidecar files, is INCREMENTAL BACKUP! If you tweak the settings on a DNG file, the whole file needs to be backed up again! Rather than a itsy bitsy XMP file. So embedded XMPs for files you edit in LR just don't make sense to me...I'd rather be touching only the little XMP. And of course, there's the date issue, and the potential for file corruption. XMPs have the disadvantage of being separate files, but they still are a better solution than writing to the file IMHO.
