Metadata about a JavaScript file

Hi,

sorry, folks, stupid technical question:

how would I add RDF metadata to a JavaScript file?

Assume I have at

http://example.org/script.js

a JavaScript file. I want to add some metadata about it, like its license. I.e. I want to be able to state e.g. 

<http://example.org/script.js> cc:license license:BSD .

Where do I put this triple?

And how can I let a tool know where this triple is, if the tool only has the script's URI?

Cheers,
Denny
