[Content Credentials : C2PA Technical Specification]
canonical
Designates the preferred version of a resource (the IRI and its contents).
[RFC6596]
chapter
Refers to a chapter in a collection of resources.
cite-as
Indicates that the link target is preferred over the link context for the purpose of permanent citation.
[RFC8574]
collection
The target IRI points to a resource which represents the collection resource for the context IRI.
[RFC6573]
compression-dictionary
Refers to a compression dictionary used for content encoding.
[RFC-ietf-httpbis-compression-dictionary-19]
contents
Refers to a table of contents.
convertedfrom
The document linked to was later converted to the document that contains this link relation. For example, an RFC can have a link to the Internet-Draft that became the RFC; in that case, the link relation would be "convertedFrom".
[RFC7991]
This relation is different than "predecessor-version" in that "predecessor-version" is for items in a version control system. It is also different than "previous" in that this relation is used for converted resources, not those that are part of a sequence of resources.
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.
[RFC6861]

[RFC9745], section 3
describedby
Refers to a resource providing information about the link's context.
[Protocol for Web Description Resources (POWDER)]
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.
[RFC6892]
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.
[RFC6579]
dns-prefetch
Used to indicate an origin that will be used to fetch required resources for the link context, and that the user agent ought to resolve as early as possible.
[HTML]
duplicate
Refers to a resource whose available representations are byte-for-byte identical with the corresponding representations of the context IRI.
[RFC6249]
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.
[RFC5023]
edit-form
The target IRI points to a resource where a submission form for editing associated resource can be obtained.
[RFC6861]

[RFC9264]
lrdd
Refers to further information about the link's context, expressed as a LRDD ("Link-based Resource Descriptor Document") resource.

[The Platform for Privacy Preferences 1.0 (P3P1.0) Specification]
payment
Indicates a resource where payment is accepted.
[RFC8288]
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.
pingback
Gives the address of the pingback resource for the link context.
preconnect
Used to indicate an origin that will be used to fetch required resources for the link context. Initiating an early connection, which includes the DNS lookup, TCP handshake, and optional TLS negotiation, allows the user agent to mask the high latency costs of establishing a connection.
[HTML]
predecessor-version
Points to a resource containing the predecessor version in the version history.
[RFC5829]
prefetch
The prefetch link relation type is used to identify a resource that might be required by the next navigation from the link context, and that the user agent ought to fetch, such that the user agent can deliver a faster response once the resource is requested in the future.
[HTML]
preload
Refers to a resource that should be loaded early in the processing of the link's context, without blocking rendering.
[Preload]
Additional target attributes establish the detailed fetch properties of the link.
prerender
Used to identify a resource that might be required by the next navigation from the link context, and that the user agent ought to fetch and execute, such that the user agent can deliver a faster response once the resource is requested in the future.
prev
Indicates that the link's context is a part of a series, and that the previous in the series is the link target.
[HTML]
preview
Refers to a resource that provides a preview of the link's context.

[RFC6903], section 4
profile
Identifying that a resource representation conforms to a certain profile, without affecting the non-profile semantics of the resource representation.
[RFC6906]
Profile URIs are primarily intended to be used as identifiers, and thus clients SHOULD NOT indiscriminately access profile URIs.

related
Identifies a related resource.
[RFC4287]
restconf
Identifies the root of RESTCONF API as configured on this HTTP server. The "restconf" relation defines the root of the API defined in RFC8040. Subsequent revisions of RESTCONF will use alternate relation values to support protocol versioning.

section
Refers to a section in a collection of resources.
self
Conveys an identifier for the link's context.

[RFC7089]
A TimeMap for an Original Resource is a resource from which a list of URIs of Mementos of the Original Resource is available.

[RFC6903], section 6
ugc
Refers to a resource that is within a context that is User Generated Content.

[RFC5829]
via
Identifies a resource that is the source of the information in the link's context.
[RFC4287]
webmention
Identifies a target URI that supports the Webmention protocol. This allows clients that mention a resource in some form of publishing process to contact that endpoint and inform it that this resource has been mentioned.
This is a similar "Linkback" mechanism to the ones of Refback, Trackback, and Pingback. It uses a different protocol, though, and thus should be discoverable through its own link relation type.
working-copy
Points to a working copy for this resource.
[RFC5829]
working-copy-of
Points to the versioned resource from which this working copy was obtained.
[RFC5829]
