This page lists the allowed extension values for the rel="" attribute in HTML5. You may add your own values to this list, which makes them legal HTML5 rel values. We ask that you try to avoid redundancy; if someone has already defined a value that does roughly what you want, please reuse it. Note that rel tokens are ASCII-lowercase before comparison against canonical value, so the canonical values should be listed without uppercase ASCII letters. | This page lists the allowed extension values for the rel="" attribute in HTML5.

| external resource | |||
| not allowed | |||
| The referenced file contains a set of rules that associates strings of characters (e.g. words) with pronunciation instructions. For example, a rule can define whether the word "tomato" is to be spoken in the british or north-american way. These pronunciation rules should be processed by voice-enabled user-agents (e.g. web browsers that support TTS rendering), but conversely, "pronunciation" link/rel files can be completely ignored by systems that do not have speech capabilities. An example of possible format is W3C PLS (Pronunciation Lexicon Specification), with the MIME type "application/pls+xml" (and usually, the extension ".pls"). When several pronunciation lexicons are referenced within a single HTML document, and/or when a pronunciation rule is specified more than once for a given string of characters, the last occurrence of the rule takes precedence (in document order), such that any previously-defined pronunciation rule gets overridden. | |||

This document is obsolete.
For more information, see: Microformats: existing rel values
This page lists the allowed extension values for the rel="" attribute in HTML5. You may add your own values to this list, which makes them legal HTML5 rel values. We ask that you try to avoid redundancy; if someone has already defined a value that does roughly what you want, please reuse it. Note that rel tokens are ASCII-lowercase before comparison against canonical value, so the canonical values should be listed without uppercase ASCII letters.

|
Brief description | Link to more details | Synonyms | Status |
---|---|---|---|---|---|---|
pronunciation | external resource | not allowed | The referenced file contains a set of rules that associates strings of characters (e.g. words) with pronunciation instructions. For example, a rule can define whether the word "tomato" is to be spoken in the british or north-american way. These pronunciation rules should be processed by voice-enabled user-agents (e.g. web browsers that support TTS rendering), but conversely, "pronunciation" link/rel files can be completely ignored by systems that do not have speech capabilities. An example of possible format is W3C PLS (Pronunciation Lexicon Specification), with the MIME type "application/pls+xml" (and usually, the extension ".pls"). When several pronunciation lexicons are referenced within a single HTML document, and/or when a pronunciation rule is specified more than once for a given string of characters, the last occurrence of the rule takes precedence (in document order), such that any previously-defined pronunciation rule gets overridden. | Pronunciation Lexicon Specification (PLS) Version 1.0 (W3C Recommendation 14 October 2008) Previously-filed bug #7601 |
Proposal | |
accessibility | hyperlink | hyperlink | The linked document contains accessibility information for the linking document. | Bruce Lawson | Proposal | |
acquaintance | hyperlink | hyperlink | the person represented by the current document considers the person represented by the referenced document to be an acquaintance | XFN | Accepted | |
admin | hyperlink | hyperlink | The linked document contains administrative option(s) for the current document and related pages. | option | Proposal | |
ajax | not allowed | hyperlink | The link is controlled through javascript, and will load the page linked to though an ajax interface. Without javascript, it should behave as a normal "a" tag, and content change is done server side. | Proposal | ||
alternate | See HTML5 | |||||
answer | hyperlink | hyperlink | A link to the answer to the question this section or document asks, e.g. in a FAQ or in a sample exam. Unlike ‘reply’ or ‘comment’ this resource necessarily solves the problem. | Q&A | (reply, comment) | Proposal |
application-manifest | external resource | Not allowed | A manifest for this web application. The manifest contains metadata about the web application, such as its name, description, and permissions the application might require. | Proposal | ||
archives | See HTML5 | |||||
author | See HTML5 | |||||
bookmark | See HTML5 | |||||
canonical | hyperlink | not allowed | Robots (e.g., search engines) should treat the document containing the tag as a minor variation of the linked document, which may result in the removal of the former from a web index and in the consolidation of its quality signals in the latter. Links with rel=canonical must not specify a language, type, or different kind of media; the referenced document must have the same language, type and target media. | [1] | Proposal | |
canonical-domain | external resource | not allowed | More than one domain may have largely similar or identical content but only one of the domains should be indexed for search engines. E.g., a company may have short and long domain names for the same content.
For security against traffic theft, rev must be meaningless. |
Google's analogous service and Talk for this page | Proposal | |
canonical-first | external resource | hyperlink | Where the canonical value should point to a group of pages, but the link can point to only one page, the group of pages can be clarified by choosing the first page in the group and assigning the URL for this rel link.
For security against traffic theft, rev must be meaningless. |
Talk for this page | Proposal | |
canonical-human | external resource | hyperlink | Pages about a person across many websites can be associated based on name, nationality, birthplace, dates of birth and death, when flourished, and other identifiers.
Search engines could more consistently aggregate same-person pages with less confusion due to name similarity. |
W3C Bug 7681 | Proposal | |
canonical-organization | external resource | hyperlink | Pages about an organization across many websites can be associated based on name, headquarters site, and other identifiers.
Search engines could more consistently aggregate same-organization pages with less confusion due to name similarity. |
W3C Bug 7682 | Proposal | |
canonical-wwwnone | external resource | hyperlink | Both bare and www-prefixed domain names usually direct to the same site. Especially when external links to a site vary in the form used, search engine indexing concentrated on only one domain form may raise its credibility. The rel value is the form preferred for indexing, e.g., href="http://example.net". Nothing to the right of the top-level domain is needed.
For security against traffic theft, rev must be meaningless. |

external resource | hyperlink | The referenced document is recommended for printing, even though the referent document is capable of being printed and both documents are of the same type, medium, and language.
