This release is the first release towards Exempi 2.0. It is based on Adobe own XMP SDK and unlike the original Adobe code, it builds fine on Linux, and even more on x86_64 (I'm not proud of the fix, but it is as good as it gets for now). This version is much more feature complete than Exempi 0.5.1 as it read and writes (serialize) XMP metadata and load from and to files, including, for supported file types, reconciling the existing metadata.
It is licensed under the BSD license.
The current API is somewhat not definitive, but I hope it is OK. The documentation still has to be written / generated.
One of the question I got asked is how do you add XMP metadata like CC:Licensing to a PDF. Here is a snippet:
#include <exempi/xmp.h> ... XmpFilePtr f; f = xmp_files_open_new("test.pdf", XMP_OPEN_FORUPDATE); XmpPtr xmp = xmp_files_get_new_xmp(f); xmp_set_property(xmp, NS_XAP_RIGHTS, "Copyright", "(c) ACME Inc., some rights reserved" " - This work is licensed to the public under the Creative Commons Attribution-ShareAlike " "license http://creativecommons.org/licenses/by-sa/2.0/"); xmp_files_put_xmp(f, xmp); xmp_free(xmp); xmp_files_close(f, XMP_CLOSE_SAFEUPDATE);
Now a little call: Exempi 1.99.0 supports several media format, but not vorbis... I wish I could add support for it. Any idea? I haven't actually dug into it yet.
 could be any of the other supported file types
