In this example, Zotero is displaying the references it can retrieve. The OpenURL referrer is responsible for the Find in a library links.

ContextObjects in Spans (COinS) is a unmaintained method of embedding latent

resolver
to find a mediated link. A principal advantage of using COinS, rather than giving a static OpenURL, is that the client can determine which resolver to use. This allows, for instance, searching for a copy of a book in one's own library.

COinS have been added to various parts of Wikipedia. They are basically just a chunk of

bibliographic
information stored in a way that machines can read. This has two applications:

  • The information can be converted into a full OpenURL and resolved by a local OpenURL resolver.
  • The information can be stored by bibliographic tools like Zotero.[1] The tool can download the bibliographic information from an article into a personal library for future research and retrieval.
    • Zotero also has Wikipedia export,[2] which allows references to be dragged into a Wikipedia edit box, where they will appear formatted as Wikipedia citation templates.

So far, COinS have been added to:

Template

For use on templates generating COinS:

{{UF-COinS}}

It adds pages to the above category.

Templates needing COinS

COinS could, and should, be added to these templates:

COinS in citation templates

The COinS keys used in most Citation Style 1 templates are listed at Module talk:Citation/CS1/COinS.

Pollution

Incorrect data in fields can pollute the metadata. For example, adding all of the authors into the deprecated |authors= parameter:

Markup Renders as

This would pollute the metadata, therefore the citation template suppresses the generation of metadata for |authors=, thereby omitting vital citation data from being submitted.
