This template embeds COinS metadata in the HTML output, allowing reference management software to retrieve bibliographic metadata. See: Wikipedia:COinS. As a general rule, only one data item per parameter. Do not include explanatory or alternate text:

• Use |date=27 September 2007 not |date=27 September 2007 (print version 25 September)

Use of templates within the citation template, is generally discouraged as many of these templates will add a lot of extraneous HTML or CSS that will be rendered in the metadata. Also, HTML entities, for example  , –, etc, should not be used in parameters that contribute to the metadata.

COinS metadata is created for these parameters:

• |periodical=, |journal=, |newspaper=, |magazine=, |work=, |website=, |encyclopedia=, |encyclopaedia=, |dictionary=
• |chapter=, |contribution=, |entry=, |article=, |section=
• |title=
