Links to a URI of a document where this SIOC object is located. Usually sioc:link is not needed because it can be assigned directly as a URI of this SIOC object. It is recommended that its usage is limited only to those cases where a document's URI may not be assigned to the object itself.

For example, this may occur in a page that contains a number of objects (e.g. comments to a blog post) that can not be addressed individually.
