Support of XMP metadata

[Olivier Tilloy]

Since version 0.16, exiv2 supports reading and writing XMP (Extensible Metadata Platform) metadata in image files.
This bug will track the implementation of this feature in pyexiv2.

I have in mind a complete rewrite of pyexiv2 to clean up the API and make it more consistent.
This will be the occasion to add support for XMP metadata, and should be tagged as version 0.2.

Any update on this? User request XMP support in Phatch ;-)

(too) slow progress in the 0.2 branch...

[Olivier Tilloy (osomon)]

XMP support is now pretty stable (from my limited tests) in the 0.2 branch.
I still need to implement a bunch of to-python value converters for some XMP types, but most of the work is done.

[Olivier Tilloy (osomon)]

I'm now closing the bug as XMP metadata read/write is implemented. There are some caveats but the main functionality is there, separate bugs should be reported to address specific issues.
Note that some raw value to pythonic value conversions are not implemented (mostly for complex types and structures), but in any case the API gives read/write access to the raw value.
