An important addition in this release is the ability to serialize XMP to a string, making sidecar XMP possible. The soon-to-be-released Liblicense 0.1 already takes advantage of this feature; it uses Exempi to read and write licenses within XMP sidecar.

Hopefully, the API will soon stabilize in preparation for the 2.0 release.

His blog post includes a nice snippet of code showing how to apply a CC license to a PDF:


#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"

xmp_files_put_xmp(f, xmp);
xmp_free(xmp);
xmp_files_close(f, XMP_CLOSE_SAFEUPDATE);


Excellent news for the community, and for the continuing saga of XMP.

The 4.1.1 XMP Toolkit (SDK) has been finalized and moved to the Adobe’s Developers Center. The 4.1 Toolkit is now available under the BSD license for open source developers.

Although the previous Adobe open source license is quite open, we decided that is was best to use a standard open source license that is respected in the open source community. Opensource.org was invaluable in reviewing the many different open source licenses that are available.

The 4.1.1 XMP release is significant because it include the source code for developers to read, write and update XMP in popular image, document and video file formats including JPEG, PSD, TIFF, AVI, WAV, MPEG, MP3, MOV, INDD, PS, EPS and PNG.

Also, please help digg this so more can find out about it!

I’m having some other discussions with all the above mentioned folks with regards to how this is going to pan out, but all I can say is that it is going to encouage XMP to flourish, and return help smooth out metadata and embedding across the board.

This really frees up the space for more developments
