Technical Details
Archive.org has implemented 1) a license chooser in the upload process, 2) the CC marks on works licensed/copyright waived with CC, 3) a subset of the CC REL metadata specification, and 4) a way to search for CC licensed content.
License Chooser
Archive.org implements the creativecommons.org license chooser.
During the file upload process you are confronted with this option:
Clicking either one of those options opens up a window to creativecommons.org in which you can select a CC license or dedicate your upload to the public domain using CC0.
Here is what the code looks like for the CC license chooser:
<a id="chooseLicenseLink" href="http://creativecommons.org" onclick="javascript:window.open('http://creativecommons.org/license/?partner=ia&exit_url=http://www.archive.org/services/license-chooser.php?license_url=[license_url]%26license_name=[license_name]%26license_image=[license_button]%26deed_url=[deed_url]&jurisdiction_choose=1','popup','width=600,height=600,scrollbars=yes,resizable=yes,toolbar=no,directories=no,location=yes,menubar=no,status=yes'); return false;">Choose license</a>
And here is what the code looks like for the public domain dedication: <a href="http://creativecommons.org" onclick="javascript:window.open('http://creativecommons.org/license/publicdomain-direct?partner=ia&exit_url=http://www.archive.org/services/license-chooser.php?license_url=[license_url]%26license_name=[license_name]%26license_image=[license_button]%26deed_url=[deed_url]&jurisdiction_choose=1','popup','width=600,height=600,scrollbars=yes,resizable=yes,toolbar=no,directories=no,location=yes,menubar=no,status=yes'); return false;">dedicate to the public domain</a>
License/PD Mark
CC license and public domain markers appear on Archive.org in many places. For pages of objects marked as licensed under Creative Commons, an image typically appears in the left hand sidebar.
For example, see this page:
Sometimes a link to the license will appear in the description area of the page.
For example see this page:
The CC0 mark appears on pages for works that have been dedicated to the public domain by the creator.
For example, see this page:
And a link to the waiver appears in the description:
Metadata
Archive.org has implemented a subset of the CC REL specification by including the rel="license" attribute in links to the CC license deeds.
For example, see the source to this page:
<a rel="license" href="http://creativecommons.org/licenses/by/3.0/" target="_blank" ><img title="[Attribution 3.0]" alt="[Attribution 3.0]" style="height:31px" id="ccimage" src="http://i.creativecommons.org/l/by/3.0/88x31.png"/></a>
