2013-03-21 Expert Review Mark Nottingham, Julian Reschke, Jan Algermissen about Refers to a resource that is the subject of the link's context. , section 2 alternate Refers to a substitute for this context appendix Refers to an appendix. archives Refers to a collection of records, documents, or other materials of historical interest. author Refers to the context's author. bookmark Gives a permanent link to use for bookmarking purposes. canonical Designates the preferred version of a resource (the IRI and its contents). chapter Refers to a chapter in a collection of resources. collection The target IRI points to a resource which represents the collection resource for the context IRI. contents Refers to a table of contents. copyright Refers to a copyright statement that applies to the link's context. create-form The target IRI points to a resource where a submission form can be obtained. current Refers to a resource containing the most recent item(s) in a collection of resources. describedby Refers to a resource providing information about the link's context. describes The relationship A 'describes' B asserts that resource A provides a description of resource B. There are no constraints on the format or representation of either A or B, neither are there any further constraints on either resource. This link relation type is the inverse of the 'describedby' relation type. While 'describedby' establishes a relation from the described resource back to the resource that describes it, 'describes' established a relation from the describing resource to the resource it describes. If B is 'describedby' A, then A 'describes' B. disclosure Refers to a list of patent disclosures made with respect to material for which 'disclosure' relation is specified. duplicate Refers to a resource whose available representations are byte-for-byte identical with the corresponding representations of the context IRI. This relation is for static resources. That is, an HTTP GET request on any duplicate will return the same representation. It does not make sense for dynamic or POSTable resources and should not be used for them. edit Refers to a resource that can be used to edit the link's context. edit-form The target IRI points to a resource where a submission form for editing associated resource can be obtained. edit-media Refers to a resource that can be used to edit media associated with the link's context. enclosure Identifies a related resource that is potentially large and might require special handling. first An IRI that refers to the furthest preceding resource in a series of resources. This relation type registration did not indicate a reference. Originally requested by Mark Nottingham in December 2004. glossary Refers to a glossary of terms. help Refers to context-sensitive help. hosts Refers to a resource hosted by the server indicated by the link context. This relation is used in CoRE where links are retrieved as a "/.well-known/core" resource representation, and is the default relation type in the CoRE Link Format. hub Refers to a hub that enables registration for notification of updates to the context. This relation type was requested by Brett Slatkin. icon Refers to an icon representing the link's context. index Refers to an index. item The target IRI points to a resource that is a member of the collection represented by the context IRI. last An IRI that refers to the furthest following resource in a series of resources. This relation type registration did not indicate a reference. Originally requested by Mark Nottingham in December 2004. latest-version Points to a resource containing the latest (e.g., current) version of the context. license Refers to a license associated with this context. For implications of use in HTML, see: http://www.w3.org/TR/html5/links.html#link-type-license lrdd Refers to further information about the link's context, expressed as a LRDD ("Link-based Resource Descriptor Document") resource. See for information about processing this relation type in host-meta documents. When used elsewhere, it refers to additional links and other metadata. Multiple instances indicate additional LRDD resources. LRDD resources MUST have an "application/xrd+xml" representation, and MAY have others. monitor Refers to a resource that can be used to monitor changes in an HTTP resource. monitor-group Refers to a resource that can be used to monitor changes in a specified group of HTTP resources. next Indicates that the link's context is a part of a series, and that the next in the series is the link target. next-archive Refers to the immediately following archive resource. nofollow Indicates that the context’s original author or publisher does not endorse the link target. noreferrer Indicates that no referrer information is to be leaked when following the link. payment Indicates a resource where payment is accepted. This relation type registration did not indicate a reference. Requested by Joshua Kinberg and Robert Sayre. It is meant as a general way to facilitate acts of payment, and thus this specification makes no assumptions on the type of payment or transaction protocol. Examples may include a web page where donations are accepted or where goods and services are available for purchase. rel="payment" is not intended to initiate an automated transaction. In Atom documents, a link element with a rel="payment" attribute may exist at the feed/channel level and/or the entry/item level. For example, a rel="payment" link at the feed/channel level may point to a "tip jar" URI, whereas an entry/ item containing a book review may include a rel="payment" link that points to the location where the book may be purchased through an online retailer. predecessor-version Points to a resource containing the predecessor version in the version history. prefetch Indicates that the link target should be preemptively cached. prev Indicates that the link's context is a part of a series, and that the previous in the series is the link target. preview Refers to a resource that provides a preview of the link's context. , section 3 previous Refers to the previous resource in an ordered series of resources. Synonym for "prev". prev-archive Refers to the immediately preceding archive resource. privacy-policy Refers to a privacy policy associated with the link's context. , section 4 profile Identifying that a resource representation conforms to a certain profile, without affecting the non-profile semantics of the resource representation. Profile URIs are primarily intended to be used as identifiers, and thus clients SHOULD NOT indiscriminately access profile URIs. related Identifies a related resource. replies Identifies a resource that is a reply to the context of the link. search Refers to a resource that can be used to search through the link's context and related resources. section Refers to a section in a collection of resources. self Conveys an identifier for the link's context. service Indicates a URI that can be used to retrieve a service document. When used in an Atom document, this relation type specifies Atom Publishing Protocol service documents by default. Requested by James Snell. start Refers to the first resource in a collection of resources. stylesheet Refers to a stylesheet. subsection Refers to a resource serving as a subsection in a collection of resources. successor-version Points to a resource containing the successor version in the version history. tag Gives a tag (identified by the given address) that applies to the current document. terms-of-service Refers to the terms of service associated with the link's context. , section 5 type Refers to a resource identifying the abstract semantic type of which the link's context is considered to be an instance. , section 6 up Refers to a parent document in a hierarchy of documents. This relation type registration did not indicate a reference. Requested by Noah Slater. version-history Points to a resource containing the version history for the context. via Identifies a resource that is the source of the information in the link's context. working-copy Points to a working copy for this resource. working-copy-of Points to the versioned resource from which this working copy was obtained.
