1. Introduction
[RFC2731] defines "Encoding Dublin Core Metadata in HTML". Newer
specifications published by the Dublin Core Metadata Initiative
(http://dublincore.org/) over the last decade, in particular
"Expressing Dublin Core metadata using HTML/XHTML meta and link
elements" ([DC-HTML]), have obsoleted this work.
Note: Implementers of RFC 2731 should note that DC-HTML introduces
a new requirement with respect to the use of the "head" element's
"profile" attribute.
2. Security Considerations
This document is of administrative nature only and therefore there
are no security relations related to it.

§1Why RFC 2731 Is Obsolete
RFC 2731 defines encoding Dublin Core metadata in HTML. The Dublin Core Metadata Initiative published newer specifications over the following decade, including one on expressing Dublin Core metadata with HTML and XHTML meta and link elements.
RFC 5791 obsoletes RFC 2731 because further development of that specification moved to the DCMI.
Newer DCMI specifications superseded the HTML metadata approach in RFC 2731. This memo records that the IETF document is obsolete.
§1The Successor Specification
The cited successor is titled "Expressing Dublin Core metadata using HTML/XHTML meta and link elements" and was published by the Dublin Core Metadata Initiative in August 2008.
The memo notes that implementers of RFC 2731 should pay attention to the newer specification's requirement concerning the profile attribute of the head element.
The DCMI document is the newer reference for expressing this metadata in HTML or XHTML. It changes a requirement related to the head element's profile attribute.
§2Administrative Status
RFC 5791 describes itself as administrative in nature. Its security section says there are no security relations related to the memo.
This memo records an administrative change and says it has no related security considerations.
