Introduction RFC 5988 [RFC5988] defined a way of indicating relationships between resources on the Web. This document specifies the 'disclosure' link relation type. It designates a list of IPR disclosures made with respect to the material for which such relation type is specified. Please note that the term "patent disclosure" should be considered to be synonymous to "IPR disclosure" for the purposes of 'disclosure' link relation type semantics, as patent disclosures are a subset of IPR disclosures. The W3C already mandates the use of the 'disclosure' link relation type for links to patent disclosures in all its documents. However, it has long been used with no proper specification and registration. This document is to accomplish this gap and encourage wider use of 'disclosure' relation type. It formally specifies the existing practice of use of the link relation type and registers it in the registry created by RFC 5988. Please note that 'disclosure' relation type designates a different resource that 'copyright' type does; the latter refers to the copyright statement while the former is used to reference patent disclosure. Please visit RFC 5988 [RFC5988] for more information on 'copyright' relation type. 1.1. Terminology The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119]. 2. 'disclosure' Link Relation Type Whenever the 'disclosure' relation type is used, the resource at the target IRI [RFC5988] MUST represent a list of patent disclosures made with respect to the material referenced by context IRI. This also Yevstifeyev Expires July 7, 2012 [Page 2] INTERNET DRAFT 'disclosure' Link Relation Type January 4, 2012 covers the case of an empty list and a list containing one entry. 2.1. Examples This section provides an example of possible use of 'disclosure' relation type. If the page contains a list of patent disclosures made with respect to the specification found at , the latter would have the following fragment of HTML source code: ... Please visit the IPR page for the list of patent disclosures made with respect to this specification. ... Or, in the case of Link header field, the HTTP response would contain the following header field: Link: ; rel="disclosure"; title="Patent Disclosures List" (Please note that the actual header field will not contain the line break and spaces after 'rel' parameter.) 3. Security Considerations The 'disclosure' relation type is truly believed not to raise any new security issues which are not discussed in RFC 5988 for generic use of Web linking mechanism. 4. IANA Considerations IANA is asked to register the 'disclosure' link relation type in the corresponding registry, with reference to this document, using the following template: o Relation name: disclosure o Description: refers to a list of patent disclosures made with respect to material for which 'disclosure' relation is specified o Reference: RFC xxxx Yevstifeyev Expires July 7, 2012 [Page 3] INTERNET DRAFT 'disclosure' Link Relation Type January 4, 2012 5.
