COinS in WordPress

The OpenBook Book Data plug-in for WordPress by John Miedema now supports COinS.
OpenBook is for book reviewers, book bloggers, library webmasters, anyone who wants to put book covers and data on their WordPress blog or website.

OpenBook gets its covers and book data from Open Library (, the only source of bibliographic data that is both open source and open data, hence the OpenBook label.

About COinS
The goal is to embed citation metadata into html in such a way that processing agents can discover, process and make use of the metadata. Since an important use of this metadata will be to allow processing agents to make OpenURL hyperlinks for users in libraries (latent OpenURL), the method must allow the metadata to be placed any where in HTML that a link might appear. In the absence of some metadata-aware agent, the embedded metadata must be invisible to the user and innocuous with respect to HTML markup. To meet these requirements, the span element was selected. The NISO OpenURL ContextObject is selected as the specific metadata package. The resulting specification is named "ContextObject in SPAN" or COinS for short.
