Hi, I maybe have found some pyexiv2 issues now.
1) XmpTag.type returns '' in a case it should return some other value, namely 'Region' or 'RegionStruct'. Detailed information can be found in * http://dev.exiv2.org/boards/3/topics/1039#message-1065 2) If I try to set the value of a XmpBag to [''] for an empty bag containing nothing but structs, I get an "ValueError: Value not set" at write(). I was able to track this to exiv2wrapper.cpp:XmpTag::setArrayValue A (quick) fix (for me) was: // Reset the value -- _datum->setValue(0); ++ _datum->setValue(std::string("")); ++ // setValue(0) leads to "ValueError: Value not set" ++ // if array=['']I made this findings when adding MS Photo 1.2 RegionInfo and Metadata Working Group Regions schema to exiv2 for using with pyexiv2. For more information about the potential bugs see
* http://dev.exiv2.org/boards/3/topics/1039#message-1065 * http://dev.exiv2.org/boards/3/topics/1039#message-1064For testing, the new namespaces need exiv2 revision 2644 plus patch appended to issue 798 (http://dev.exiv2.org/issues/798).
