COinS is still alive and Zotero will export citations as COinS: http://www.zotero.org/support/dev/exposing_metadata/coins
I think Mendeley supports them, too.
COinS may eventually be replaced by or repurposed as some flavor of microformat, e.g. http://microformats.org/wiki/citation and http://microformats.org/wiki/book-info-examples, but I don't think there are yet standard microformats for citations, books, journals, or articles.

Subject: [CODE4LIB] COinS
I've used the COinS Generator at OCLC for years. Now it is gone. Any
suggestions on how I can get an occasional COinS for use in our
bibliography? Do any of the citation managers generate COinS?
Or is this just an old unused metadata format that should be replaced by
