ContextObjects in Spans (COinS) is a unmaintained method of embedding latent OpenURL ContextObjects in web pages. This allows client software to retrieve bibliographic metadata and to use an OpenURL 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:
- Wikipedia:Book sources – just contains the ISBN
- Many citation templates and infoboxes – see: Category:Templates generating COinS
- MediaWiki:Citethispage-content – generated when you click Cite this article; contains information for citing Wikipedia itself in other documents
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.
For example:
| Markup | Renders as |
|---|---|
{{cite book |last=Bloggs |first=Fred |editor-first=John |editor-last=Doe |title=Big Compilation Book with Many Chapters and Distinct Chapter Authors |publisher=Book Publishers |date=January 1, 2001 |pages=100–110 |chapter=Chapter 2: The History of the Bloggs Family |isbn=978-1-234-56789-7}}

Bloggs, Fred (January 1, 2001). "Chapter 2: The History of the Bloggs Family". In Doe, John (ed.). Big Compilation Book with Many Chapters and Distinct Chapter Authors. Book Publishers. pp. 100–110. ISBN 978-1-234-56789-7. |
Which renders the following HTML:

Picking out the COinS keys:
| Key | Data |
|---|---|
| rfr_id | info:sid/en.wikipedia.org: |
| rft.atitle | Big Compilation Book with Many Chapters and Distinct Chapter Authors |
| rft.au | Bloggs, Fred |
| rft.aufirst | Fred |

| rft.pages | 100-110 |
| rft.pub | Book Publishers |

Pollution
Incorrect data in fields can pollute the metadata. For example, adding all of the authors into the deprecated |authors= parameter:
| Markup | Renders as |
|---|---|
{{cite book |authors=Smith, John; Johnson, Joe; Green, Ethan |title=Big Compilation Book with Many Chapters and Distinct Chapter Authors |publisher=Book Publishers |date=January 1, 2001 |pages=100–110 |chapter=Chapter 2: The History of the Bloggs Family |isbn=978-1-234-56789-7}}

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