CitationStyles.org is the home of the Citation Style Language (CSL), a new open XML-based language to describe the formatting of citations and bibliographies.
This tool will take bibliographic metadata for a citation and produce a "COinS", i.e. a snippet of HTML that can be placed on a webpage and processed by web tools. The COinS generator also has a built-in link-resolver, so you can generate a COinS by taking any OpenURL query string and appending it to the base URL http://generator.ocoins.info/.
