 brought attention to the need of a standard way to embedding metadata into HTML pages. Daniel Chudnov suggested the use of OpenURL. Embedding OpenURL ContextObjects in HTML had been proposed before by Herbert Van de Sompel and Oren Beit-Arie and a working paper by Chudnov and Jeremy Frumkin. Discussion of the latter on the GPS-PCS mailing list resulted in a draft specification for embedding OpenURLs in HTML which later became COinS.

The adoption of COinS was pushed by various publications and implementations. The specification can now be found at http://ocoins.info/. This page includes specific guides to implement COinS for journal articles and books and a COinS generator.

Summary of the COinS data model

From OpenURL 1.0 COinS borrows one of its serialization formats (“KEV”) and some ContextObject metadata formats included in OpenURL implementation guidelines. The ContextObject implementation guidelines of COinS include four publication types (article with several subtypes, book, patent, and generic) and a couple of simple fields. However the guidelines are not required part of COinS, so the standard does not provide a strict metadata model like Dublin Core

The Dublin Core metadata terms are a set of vocabulary terms which can be used to describe resources for the purposes of discovery. The terms can be used to describe a full range of web resources: video, images, web pages etc and physical resources such as books and objects like artworks...
