XMP FileInfo panel for Adobe Creative Suites 4 and 5 now available!

Alex Kozak, December 6th, 2010

This is a special guest post by John Bishop of John Bishop Images.

Prior to Adobe’s Creative Suite 4, adding Creative Commons license metadata via the FileInfo… dialog (found in Photoshop, Illustrator, InDesign and more) meant coding a relatively simple text based XML panel definition and has been available from the Creative Commons Wiki since 2007.

Starting with Creative Suite 4 Adobe migrated the XMP FileInfo panel to a Flash based application, meaning that adding Creative Commons metadata became much more complex, requiring Adobe’s XMP SDK and the ability to develop applications in Flash, C++ or Java.

After significant development and testing john bishop images is pleased to announce the availability of a custom Creative Commons XMP FileInfo Panel for Creative Suite 4 and Creative Suite 5 – free of charge.

This comprehensive package offers the ability to specify Creative Commons license metadata directly in first class, industry standard tools and places Creative Commons licensing metadata on the same footing as the standardized, commercial metadata sets like Dublin Core (DC), IPTC and usePLUS and tightly integrates all the metadata fields required for a Creative Commons license in one panel.

Also included is a metadata panel definition that exposes the Creative Commons license metadata in the mini metadata panels found in Bridge, Premiere Pro, etc. And finally a set of templates that can be customized for the various license types and more is also included; these templates can be accessed from Acrobat.

For more information and to download the Creative Commons XMP FileInfo panel visit john bishop images’ Creative Commons page.

Note: The panels are localized and a English-US language file is supplied. To contribute localization files in other languages please contact john bishop images.

liblicense 0.8 (important) fixes RDF predicate error

asheesh, July 30th, 2008

Brown paper bag release: liblicense claims that the RDF predicate for a file’s license is http://creativecommons.org/ns#License rather than http://creativecommons.org/ns#license. Only the latter is correct.

Any code compiled with liblicense between 0.6 and 0.7.1 (inclusive) contains this mistake.

This time I have audited the library for other insanities like the one fixed here, and there are none. Great thanks to Nathan Yergler for spotting this. I took this chance to change ll_write() and ll_read() to *NOT* take NULL as a valid predicate; this makes the implementation simpler (and more correct).

Sadly, I have bumped the API and ABI numbers accordingly. It’s available in SourceForge at http://sf.net/projects/cctools, and will be uploaded to Debian and Fedora shortly (and will follow from Debian to Ubuntu).

I’m going to head to Argentina for a vacation and Debconf shortly, so there’ll be no activity from on liblicense for a few weeks. I would love help with liblicense in the form of further unit tests. Let’s squash those bugs by just demonstrating all the cases the license should work in.

Exempi 1.99.3 Released

Jason Kivlighn, July 11th, 2007

Hubert Figuiere has released Exempi 1.99.3

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.

Sidecar XMP and License Extractors in Tracker

Jason Kivlighn, July 10th, 2007

Tracker has accepted my patches to read XMP sidecar, as well as patches to extract licenses from MS Office (old format), TIFF, HTML, PNG, and PDF. This support will be available in the 0.6 release, which potentially will be released later this week.

My final set of patches will additionally add support for extracting licenses from JPEG, SVG, and OpenOffice’s OASIS. Also, through GStreamer, Tracker already recognizes licenses of Vorbis and FLAC.

This marks the half-way point of Summer of Code 2007.

More Summer of Code — Liblicense, Tracker, Beagle,…

Jason Kivlighn, June 30th, 2007

Let’s see, where am I at.

Code in GStreamer to read the license URI is getting pushed through. Now there’s Bug #451939 that updates the GStreamer API with a license and copyright uri tag. When this all gets pushed through, access to the license URI will be available through GST_TAG_LICENSE_URI and/or GST_TAG_COPYRIGHT_URI.

In Tracker, I’ve written code to handle generic indexing of embedded/sidecar XMP. Previously it just extracted the license, and now any elements can be pulled out and indexed. Currently, Dublin Core and CC elements are indexed. The code is still local, and yet to be committed.

In another direction, I’ve been lending a hand to liblicense. As mentioned in Scott’s previous post, I’ve got two i/o modules ready. Both are based on Exempi. One reads/writes license metadata directly into Quicktime, AVI, PDF, PNG, TIFF, and JPEG formats. The other read/writes sidecar XMP for any format. There’s more to come.

I also want to look into a liblicense config module and frontend for KDE4. I figure I can put my KDE programming experience to good use.

And in yet another direction, I’m looking into indexing licenses in Beagle. After browsing the code, I can adapt most of what I learned about license metadata while working with Tracker to extending Beagle. I even notice that their image formats filters already support extracting XMP, so adding the extra license checks is straightforward. A preliminary patch and request for feedback has been posted on their mailing list.

All in all, I’ve done some work here and there, for this project and that…

Liblicense is alpha!

Scott Shawcroft, June 29th, 2007

Over the last week a lot of progress has been made on liblicense. Yesterday Jason and I got the module_read and module_write functions working with a stub io module and an XMP sidecar module. Tuesday and Wednesday I got the library’s system license functions working. Today I did some memory leak plugging and wrote out the system default functions. Nearly every part of the library works as planned. While its still rough, the bulk of the library work is done.

The most common data structure I’ve been using is a null-terminated list (really an array) of strings (char*). Yesterday I wrote out some common methods to be shared throughout the library. These are in list.c. My hope is that these common functions will allow the other code to be cleaner. Next week I plan on fixing up system_licenses.c to use the list functions. At the moment it is the largest, ugliest and leakiest of all the files. That will all be fixed Monday.

After the code cleanup on Monday the much more exciting task of creating modules and clients of the library begins. We’d like to support embedding in as many file formats as possible. Without this ability, the license tracking only works locally. One of the most useful libraries so far is Exempi which can embed in a number of formats. Jason wrote an Exempi liblicense module yesterday. On my list of clients to do is a Gnome Control Panel system default, Nautilus license select, Sugar license select and Creative Commons default license chooser. Am I missing anything important? Where could licenses be integrate besides this? Perhaps Amarok or an equivalent? ccHost? Let me know what you think.

Indexing License Metadata in Tracker, Week 1

Jason Kivlighn, June 12th, 2007

Week 1 of Google Summer of Code is complete and already I’m seeing much progress. There’s a mess of formats to embed licenses into and a mess of ways to embed them. My first task has been straightening out where licenses are embedded in each format and how exactly to go about extracting them. Here’s where I’m at:

Format Form of Metadata Location of Metadata Extraction with Tracker Test content
  • XMP
  • Native id3 tags
  • For id3v24, the PRIV,XMP field
  • WCOP tag
Extracting MP3 tags has moved from an ID3 parser to handing off the work to GStreamer/MPlayer/Totem. As far as I can tell, this prevents me from extracting the XMP. XMP embedded with Exempi
PDF XMP metadata field Extend the current PDF extractor (which uses Poppler) to read the metadata field. However reading the metadata field isn’t wrapped in Poppler’s glib bindings, but I have written and submitted a patch. XMP embedded with Exempi
  • XMP
  • Native comment field
  • XMP comment field
  • LICENSE comment field
Extend the GStreamer extractor to check for the presence of an XMP comment field. GStreamer places this within the EXTENDED_COMMENTS tag (requires GStreamer 0.10.10). XMP embedded with vorbiscomment
JPEG XMP Exif XML Packet field Extend the Imagemagick extractor, using ‘convert file.jpg xmp:-’ to read XMP XMP embedded with Exempi
PNG XMP iTXt, XML:com:adobe:xmp field Extend the PNG extractor, adding a check for XML:com:adobe:xmp. (For backwards compatibility, the ability to read iTXt in libpng is disabled by default until version 1.3.) XMP embedded with Exempi
HTML RDFa <a rel=”license” href=”…”></a> Write a new HTML extractor, using libxml2, and scan for RDFa Various actual sites, including creativecommons.org
SVG RDF /svg/metadata/rdf I could specifically parse the XML, checking for the RDF schema used by Inkscape. Should I check for XMP also??? Inkscape
Any XML XMP Wherever valid Write a generic XML extractor (and/or extractor for each particular format), scanning with libxml2
OpenOffice.org (OASIS) OO.org CC License Add-In SoC Project is working on the spec OO.org Add-In
MS Office DocumentSummaryInformation Infile, CreativeCommons_LicenseURL property Extend existing msoffice extractor MSOffice Add-in

If this is all well and good, I’d like to help update the CC Wiki with updated embedding specifications.

As far as coding goes, I wrote the code for Tracker to check for and extract metadata from XMP sidecar files. XMP is parsed by Hubert’s XMP library. The timing of Adobe’s release of their XMP Toolkit and Hubert subsequently release of Exempi 1.99.x, have been an early boon to the project. The ‘license’ tag in the CC namespace is the only metadata extracted at the moment.

I’ve also been hacking the extractors of the above list of formats to determine the feasibility and processes of extracting license metadata from each.

Where I stand now is that feedback on the above would be much appreciated and if all is well I can get the XMP sidecar code I have pushed into Tracker’s Subversion repository soon.

Happy hacking, indeed.


Exempi 1.99.0 Released

Alex Roberts, May 30th, 2007

Following on from Jon’s follow-up, Hubert Figuiere has released Exempi 1.99.0, now based on Adobe’s XMP SDK.

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"
" - 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_files_close(f, XMP_CLOSE_SAFEUPDATE);

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

XMP Toolkit 4.1.1 Officially Released under BSD License

rejon, May 14th, 2007

That’s right, Gunar from Adobe, blogged it today and sent me an email! This is super great news that I want to blockquote:

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!

More XMP Toolkit Plugs

rejon, May 13th, 2007

In a follow-up to Mike’s post about XMP, I (through CC) have been working with Adobe XMP’s product manager, Gunar Penikis, on how CC and Adobe can work together on XMP. Also, in the same line, I’m friends with and working with Cyrille Berger and Hubert Figuiere, who have each noted how positive of a step releasing XMP SDK/Toolkit under a BSD license is for the larger community.

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
