References are part of Structured Data on Commons, however they are not visible to the end user and there is no interface to be able to add them. A reference (or source) is a citation that verifies the statement. A reference can be a link to a URL or an item; for example, a book. Contributors can add and manage references and readers will see the references for the statements. Currently, there is no limit to the number of references that can be added.
A statement has an Add reference button below it.
References include fields that are grouped collectively for one reference.

As a contributor, I want to add a reference, so that I can give credence to statements on Commons.
As a contributor, I want to modify or delete statement references, so the references are correct.
As a reader, I want to see references for statements on Commons, so I know the statements have been verified.
