LibraryLookup uses Creative Commons license

When somebody wrote yesterday asking whether the LibraryLookup code (such as it is!) was licensed for public-domain use, I realized this was the perfect opportunity to try out the Creative Commons licensing procedure. It couldn't have been any simpler -- it took all of about 10 minutes. I chose the Attribution-ShareAlike license:

Embedded in the HTML generated by the Creative Commons website is this slug of RDF:

<rdf:RDF xmlns=""

Method for using a JavaScript bookmarklet to extract the
ISBN from an ISBN-bearing URL and use it to look up the book elsewhere,
particularly in a local library. Related development: directories of online
lookup services offered by many libraries.

Since the whole point of this exercise was to create a meme that would propagate widely, I considered the public domain dedication. Who, after all, would try to patent something as simple and obvious as a regular expression used in a JavaScript bookmarklet to capture an ISBN and make a referral to a library? But stranger things have happened. I hope this license will accomplish two things. First, encourage linkage back to the LibraryLookup project so I can keep track of how this evolves. Second, discourage any effort to patent the idea.
