Bug #622
Exiv2 doesn't parse MicrosoftPhoto schema prefix correctly.
100%
Description
Exiv2 does not correctly parse the MicrosoftPhoto schema prefix from an XMP packet created with with Nikon Capture NX2, which uses "Public XMP Toolkit Core 3.5".
Exiv2 changes MicrosoftPhoto to MicrosoftPhoto_1_ and even MicrosoftPhoto_1__1_.
However, if the XMP packet is created from scratch with Exiv2, all is fine.

This seems to be an incompatibility between "Public XMP Toolkit Core 3.5" used by Nikon Capture NX2 and the XMPSDK used by Exiv2. It looks like something is going wrong deep inside XMPSDK.
Next steps:- Check if the problem can be reproduced with XMPSDK alone
- If so, check if the latest version of XMPSDK fixes the problem, if it doesn't, report as a bug for XMPSDK (Adobe)

Gilles,
The problem is very simple. Look at the namespace URIs: Nikon Capture NX2 uses http://ns.microsoft.com/photo/1.0 (*p*hoto), but Exiv2 has http://ns.microsoft.com/Photo/1.0/ (*P*hoto). If I make it lowercase in Exiv2, it works with the samples. But which URI is correct??

Andreas,
In last Exiftool, Microsoft XMP namespaces are :
MicrosoftPhoto => 'http://ns.microsoft.com/photo/1.0',
MP => 'http://ns.microsoft.com/photo/1.2/',
MPRI => 'http://ns.microsoft.com/photo/1.2/t/RegionInfo#',
MPReg => 'http://ns.microsoft.com/photo/1.2/t/Region#',For NX i cannot any reference...
