COinS

COinS

ContextObjects in Spans, commonly abbreviated COinS, is a method to embed bibliographic metadata in the HTML code of web pages. This allows bibliographic software to publish machine-readable bibliographic items and client reference management software to retrieve bibliographic metadata. The metadata can also be sent to an OpenURL resolver. This allows, for instance, searching for a copy of a book in one's own library.[1]

History

In the late 1990s OpenURL was created at Ghent University as framework to provide context-sensitive links. The OpenURL link server implementation called SFX was sold to Ex Libris Group which marketed it to libraries, shaping the idea of a “Link resolver”. The OpenURL framework was later standardized as ANSI/NISO Z39.88 in 2004[2]. A core part of OpenURL was the concept of “ContextObjects” as metadata to describe referenced resources.

In late 2004 Richard Cameron, the creator of CiteULike brought attention to the need of a standard way to embedding metadata into HTML pages[3]. Daniel Chudnov suggested the use of OpenURL.[4] Embedding OpenURL ContextObjects in HTML had been proposed before by Herbert Van de Sompel and Oren Beit-Arie[5] and a working paper by Chudnov and Jeremy Frumkin[citation needed]. Discussion of the latter on the GPS-PCS mailing list[6] resulted in a draft specification for embedding OpenURLs in HTML[7] 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[8]. 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 or the Bibliographic Ontology.

Use in web sites
