There are lookup services to get a standard identifier when only some bibliographic data is known - mainly OpenURL. I have not investigated whether you can easily map CSL format to OpenURL or if you need to also embed the OpenURL as twitter annotation. However all lookup services that I know are either crapy or proprietary or both. This is not a technical issue but just based on a lack of data (hopefully to get better with more linked open data). Given enough open bibliographic data anyone can create a lookup service where you throw in some title, author and this stuff and get back an identified record. I think there also are some services called "library catalog" for this purpose. Anyway this os nothing that can be solved with a bibliographic data format alone. Either you have a standard identifier or you have not. If you have not, you must rely on third party services that run independent of your bibliographic data. > It would be interesting to explore what identifiers + csl (and other > options) would look like in a twitter annotation if you had time to > mock something up in a wiki somewhere :-) I summarized my findings on CSL at http://wiki.code4lib.org/index.php/Citation_Style_Language and included some ideas of CSL and other data in twitter annotations.
