9.7 Other relevant metadata fields

A few other metadata fields affect bibliography formatting:

link-citations

If true, citations will be hyperlinked to the corresponding bibliography entries (for author-date and numerical styles only). Defaults to false.

link-bibliography

If true, DOIs, PMCIDs, PMID, and URLs in bibliographies will be rendered as hyperlinks. (If an entry contains a DOI, PMCID, PMID, or URL, but none of these fields are rendered by the style, then the title, or in the absence of a title the whole entry, will be hyperlinked.) Defaults to true.

lang

The lang field will affect how the style is localized, for example in the translation of labels, the use of quotation marks, and the way items are sorted. (For backwards compatibility, locale may be used instead of lang, but this use is deprecated.)

A BCP 47 language tag is expected: for example, en, de, en-US, fr-CA, ug-Cyrl. The unicode extension syntax (after -u-) may be used to specify options for collation (sorting) more precisely. Here are some examples:

• zh-u-co-pinyin – Chinese with the Pinyin collation.
• es-u-co-trad – Spanish with the traditional collation (with Ch sorting after C).
• fr-u-kb – French with “backwards” accent sorting (with coté sorting after côte).
• en-US-u-kf-upper – English with uppercase letters sorting before lower (default is lower before upper).

notes-after-punctuation

If true (the default for note styles), pandoc will put footnote references or superscripted numerical citations after following punctuation. For example, if the source contains blah blah [@jones99]., the result will look like blah blah.[^1], with the note moved after the period and the space collapsed. If false, the space will still be collapsed, but the footnote will not be moved after the punctuation. The option may also be used in numerical styles that use superscripts for citation numbers (but for these styles the default is not to move the citation).
