This modules provides a way to convert document identifiers, such
as DOIs, ISBNs, arXiv IDs to bibliographic references.
Each type of identifiers will be converted via internet services
to a bibliographic record of type Text.CSL.Reference , which in
turn can be rendered in various format using citeproc-hs package
http://hackage.haskell.org/package/citeproc-hs .
Moreover, the server responses are cached in a local database,
making the server load as little as possible.
At the moment, citation-resolve requires xsltproc executable
to parse xml, in order to resolve ISBNs.
