License Deeds (Metadata)
Creative Commons license deeds will display information about the referring work if available. This page documents what information is displayed by the deeds.
How it Works
When you visit a CC legal deed by clicking on a link from a licensed work, CC looks at the page you came from (the referrer) to see if it contains information about the licensed work. This information can include how the creator wants to be attributed, who identified a work as in the public domain, etc. If present, this information is displayed for the user, and used to generate copy and paste attribution/citation HTML.
Works that require a password to access them can not be checked by the server software.
If the referring page contains multiple works under the same license (even with properly scoped metadata), we can not determine which link was clicked on. In that situation, we err on the side of certainty and do not display the information.
If the software can not unambiguously determine the title or attribution information, we err on the side of certainty and do not display the information.
To see the examples, visit the work pages (listed here) and click through to the deed.
