RE: XMP tagging for PDFs no go!
As far as I know, you are limited to TIFF and JPEG at this time. And its
mostly Exif, with some (but not all) properties from the Dublin Core
namespace. Check the MSDN docs, its documented under WPF.
The XMP specs allow XMP blocks in a number of different file formats
(including PDF 1.4 and higher and PSD) as well as sidecar files (XMP is
stored in a text file with the same file name, but with the extension .XMP).
But this does not mean that WPF has to support al of them. It does allow you
to create your own file format filter for metadata, full text (search),
thumbnailing and preview.
Be aware, though, that interoperability is a true challenge. Nested keywords
are handled totally different in Adobe Lightroom, MS iView (soon Expression
Media) and Vista Photo Gallery - none of these apps map to each other... :-(
