it will open a virginroad of Creative Commons(CC) for me
(i never tried to attach CC to my contents so far).
i may be wrong but i understand the policy as follows.
according to the site, the function of ccpublisher seems:
- can create CC metadata in an RDF format
- cannot embed metadata to the legacy file format like jpg, png, mp3, wma, pdf, MSOffice
as a conclusion,
- it is useful only when you deliver the content you want as "a file included in a html document"
