Proposal to promote "citation" property to CreativeWork

Submitted by the Schema Bib Extend Group
Detail in Schema Bib Extend Wiki

Overview

The "citation" property is already defined in the MedicalScholarlyArticle Type, as "A citation or reference to another creative work, such as another publication, web page, scholarly article, etc. ". However, a citation can be found within any kind of document (and other kinds of works), so this property should be available on the CreativeWork Type.

Proposal

The promotion of the "citation" property to the CreativeWork Type.


Example

Citation of an article and a book within a document

<article itemscope itemtype="http://schema.org/ScholarlyArticle">
