XMP sidecar ignored if named incorrectly.
I imported files into Darktable and Darktable ignored them
img_8211.jpg came with img_8211.xmp

See you ticket #8533. You can rename the .xmp files to have them read.
I'm leaving this one open. Maybe someone would like to add reading of these xmp files? However, keep in mind, that then there are two sidecar files which will diverge over time. Not good.

Replying to [comment:4 mcbofh]:
I'm pretty sure this can be closed - the filename that Darktable looks for is
filename is 20120310_135601_IMG_8999
extension is CR2
I'm pretty sure that this is what the bug is about. It is just wrong.
the XMP sidecar is NOT (filename).(extension).xmp but rather (filename).xmp. The XMP spefication is pretty clear.
Darktable is the one doing it wrong and that's what the original bug is about. By not supporting what all the other XMP producers are doing you are just ignoring everything else.

Freely quoting dinamic:
"It's all about safety, we do not write to source images, nor into others XMP files and we dont want other apps to write into ours. We are not using XMP as an data shuffling synchronization protocol between applications which it is not designed for."
Other applications don't support our name space either way so there's no point in providing them a file they can't use in a sensible way.
We might add import support for other XMP files and other application's tags at some point.

"It's not a bug, it's a feature!"
Then, instead of Extensible Metadata Platform, maybe you should use Metadata Platform, or other extension, just to avoid to mean what is not. The standard is designed to be extensible, allowing users to add their own custom types of metadata into the XMP data.
Modifying XMP files is like modifying exif data in an jpg.
