Using the experimental license choosers at
CC Labs
you can provide some optional information about your work, including a
URL to be used for attribution and a URL where rights beyond the scope
of the public Creative Commons license may be obtained.
If you provide any optional information it will be included in the
license notice HTML generated for your site. The optional information
will also be annotated so that a computer may discern, e.g., the URL
you want used for attribution purposes.

The HTML rendered in the box above includes metadata. Click on
the license button and the license deed will update itself to display
metadata scraped from this page after a few moments.
If you're using Firefox or Safari (patches welcome for IE), you can see the metadata revealed without leaving this page by clicking
this RDFa bookmarklet link
(right click to bookmark the link and use on other pages).
MozCC
(also for Firefox) can also reveal this metadata.
Background
Note that the bookmarklet above reveals that text and links intended
for human use are annotated directly. This is a big improvement over
our use of RDF/XML embedded in HTML comments for extra metadata, which
is hard for both humans and computers to see and understand.
Colocation of metadata and viewable content is accomplished above
with
RDFa
, which uses
attributes to annotate HTML elements.
There are some obstacles to RDFa adoption (it uses attributes
that do not validate in current versions of [X]HTML) and
microformats
have lots of momentum, so we're also exploring a microformat
or microformats for work information and other annotations that
complement CC licensing. (But RDFa was easier to get up and running
for this demo because we didn't need to write a parser.)
One of the strengths of the microformats process is
an emphasis on documenting use cases in the wild before
attempting to standardize. We've begun doing just this on a
licensing examples
page on the microformats wiki
, which is an excellent place to get
a feel for the range of uses that could be enhanced by metadata in the
near future.

Examples
There are a few early experimenters publishing extended metadata that
will work in the same fashion as the artificial demo above. Visit any of
these, click on a CC license button, and see how the metadata is added
to the CC license deed.
Magnatune
has long been an
innovator in this space. Visit any album page, for example Anup's
Embrace
Pump Audio
is
a leader in commercial licensing of music and now offers
a CC option to interested musicians. For an example see
Gary Robinson
BeatPick
is a "fair play" record label that offers music under a CC license and handles commercial licensing and sales for artists. Visit any artist page, for example
2 Seconds Away
Jamendo
is a "is a new model for artists to promote, publish, and be paid for their music." Nearly 2000 albums are streamable, downloadable via P2P, and many may be purchased via artists' sites, for example, Revolution Void's
Increase the Dosage
Scoopt
makes it easy to sell your
pictures and blog content to the press. Like Pump Audio, they offer a
CC license option when a user gets a button for commercial licensing (
press
).
One of the first blogs to get a Scoopt button with metadata that works
with this demo is
Kitchen
