So do you mean essentially filling in some metadata in the file to indicate what license is used? This could be done both for individual files exported from audacity, and for audacity projects themselves. There is also the corresponding exercise of detecting such tags when a file is opened to form a new project and applying it to the new project (as is done with ID3 tags). This could potentially make applying attribution licenses much easier, as the attribution would be carried along by default whenever the file was edited. > I'd like to include this in Audacity - perhaps a checkbox and dialog > box reachable via Audacity's "Edit ID3 Tags" option.

Sounds like a good idea. We would probably want to be able to extend the idea to allow other licenses to be specified (used-defineable) so that users in the commercial sector can specify copyright information and the like. > Obviously, there is a risk of this implementation being clumsy, or > slowing the workflow.

The people to talk to would be the audacity-devel mailing list: http://lists.sourceforge.net/lists/listinfo/audacity-devel Key pointers would be to work against the CVS HEAD code (rather than released tarballs), and use the wxwidgets structures and existing libraries wherever possible (we already link libid3tag and libvorbis into audacity).

A while ago I wrote to the list about using taglib unstead of id3lib/id3tag as it's the only free one supporting a) newest id3v2 spec and b) multiple fileformats (MP3, Ogg Vorbis, FLAC and MPC) by having abstract layer. Rob, maybe you could evaluate this possibility and make it happen as part of your changes. Alexandre |

It's nothing more than a small data chunk, that can be ready by all audio database apps that know it(Soundminer, Netmix, Basehead, FXLibrary). I am not aware of libraries that do this, but then I'm not a coder. Info links: http://www.sr.se/utveckling/tu/bwf/ (had a chunk viewer to check if it's written properly too) http://www.digigram.com/support/library.htm?o=getinfo&ref_key=286 http://www.digitalpreservation.gov/formats/fdd/fdd000003.shtml http://www.ebu.ch/en/technical/publications/userguides/bwf_user_guide.php Btw, it is used by most recorders to timestamp files, so it may be a brilliant way to keep timecodes of recordings in the recorded files themselves in Audacity. It could be another level of security for recovering broken sessions. Tony |
