| − | == [[License metadata validation web service]] ==
| |
| − | | |
| − | Creative Commons offers [[Creative Commons Web Services|web services]] for integrating license selection into applications, and we have a [http://validator.creativecommons.org License Metadata Validator]. How about mashing the two of them up? A web service which allowed applications to validate license metadata would allow applications to integrate another aspect of CC licensing with minimal effort.

| − | | |
| − | == [[CC Web Service Wrappers]] ==
| |
| − | | |
| − | We currently offer language-specific wrappers for the [[Creative Commons Web Services]] in Python, Java and PHP. Help make it easier for other developers to integrate license selection by writing a wrapper library in your language of choice. Lisp, anyone?
| |
| − | | |
| − | A successful implementation will include a small driver application which demonstrates how the wrapper can be used for license selection. See [[Web Services Client Implementations]] for information on our existing implementations.
| |
| − | | |
| − | == [[APIs for Creative Commons license metadata]] ==
| |
| − | | |
| − | We provide RDF metadata for each our our licenses and the public domain dedication. Many developers will find it easiest to access this metadata via a programming language-specifc API. [http://cclicense.sourceforge.net/ cclicense.php] is an example of such an API for PHP web developers. Ada, C++, E, Java, Lisp, ML, Perl, Ruby, Smalltalk, Tcl (and many more!) are all up for grabs. Your wrapper should also include a small driver program to demonstrate how it can be used to pull license information. Bonus points if your implementation can dynamically discover and wrap new licenses using the Creative Commons metadata vocabulary.

| |
| − | | |
| − | * APIs for [http://workspaces.gotdotnet.com/cclib C#] (Steve Griffin) and [http://yergler.net/projects/ccrdf/ Python] (Nathan Yergler) have been created in response to this challenge.

| − | * Please help write this summary :)

| − | == License metadata in SMIL and SVG ==
| |
| − | | |
| − | SMIL (multimedia playlists) includes support for [http://www.w3.org/TR/smil20/metadata.html#edef-metadata RDF/XML metadata]. We need examples of including license metadata in SMIL for the purposes of denoting that a SMIL playlist itself is published under a Creative Commons license or that individual components of the playlist are licensed. Even better if you can use dc:source to specify parent playlists/works. (SVG has similar support for [http://www.w3.org/TR/SVG11/metadata.html RDF/XML metadata].) Read more about the motivation in this [http://lists.ibiblio.org/pipermail/cc-metadata/2003-October/000185.html cc-metadata] post.

| − | === Implementations ===
| |
| − | | |
| − | * Lucas Gonze has created a [http://gonze.com/cc-smil.html CreativeCommons SMIL Module]
| |
| − | * [[Inkscape]] includes support for SVG metadata.
| |
| − | * [http://search.cpan.org/~bryce/SVG-Metadata-0.28/ SVG::Metadata] by Bryce Harrington is a PERL module for including metadata inside an SVG (used by [http://www.openclipart.org Open Clip Art Library].

| − | === TODO ===
| |
| − | | |
| − | * generalize to all xml formats, split into separate challenges
| |
| − | | |
| − | == [[Companion File metadata specification]] ==
| |
| − | | |
| − | It is impractical to embed metadata in some file formats, so we need a specification for a "companion" metadata file that would define license and other metadata information.
| |
| − | | |
| − | == Operating System Support For Creative Commons Metadata ==
| |
| − | | |
| − | Recent and upcoming operating systems will have built-in support for application-level metadata. See [http://developer.gnome.org/arch/file/metadata.html Gnome], [http://msdn.microsoft.com/longhorn/understanding/pillars/winfs/default.aspx?pull=/msdnmag/issues/04/01/WinFS/default.aspx Vista], and [http://www.apple.com/macosx/tiger/searchtechnology.html Tiger]. How can Creative Commons take advantage of these technologies to enable CC-aware search and applications on the next generation desktop? Wanted: research briefs on how to expose CC license info for objects in each major OS or framework. Support for the external metadata files should be included.
