notes

  • rel="alternate" can take further meaning from additional attributes, such as
    • rel="alternate" lang="fr" (French language version of this page)
    • rel="alternate" media="print" (printable version of this page)
    • rel="alternate" media="handheld" (version of the page intended or better for handheld/portable devices like PDAs, cell phones, etc.)
  • Synonyms such as "previous", "toc" are not as widely supported as the main term.

propositions

A few rel values have been developed as drafts as a result of going through most of the microformats The microformats process, and are thus listed here for your serious consideration. You may use these values, and if you find any problems with them please point them out on the respective "issues" page for the rel value.

rel value résumé proposé dans
directory …indicates that the destination of the hyperlink is a directory listing containing an entry for the current page. rel-directory
enclosure …indicates that the destination of that hyperlink is intended to be downloaded and cached. rel-enclosure
payment rel-payment


brainstorming

Several rel values are being brainstormed as potential microformats and are thus listed here. If you find you have a use for such semantics in real world examples, consider trying out these values and provide feedback on the respective brainstorming page(s) with your results and experiences.

cite indicate[s] that the destination of that hyperlink is an authoritative source or a precedent to the current page. distributed-conversation-brainstorming

Usage CHIC

Il existe plusieurs valeurs rel utilisées comme CHICs, à la fois dans la jungle, dont les origines ne sont pas forcément connues, ni le fait que leurs sens soient cohérents. Il existe aussi plusieurs valeurs rel provenant de propositions externes avec différents degrés de mérite. Il est utile de documenter leur existence et de résumer leurs objectifs de sens/usage comme une recherche qui pourra être utilisée pour peut-être en prendre une ou plusieurs en considération à travers le processus microformats s'il y a à la fois suffisamment d'intérêt et qu'il en existe suffisamment dans l'usage dans la jungle.

WCLR

La proposition du WCLR est décrite par son auteur (dans un e-mail, 2007-09-25) comme :

…now effectively obsolete, since HTML5 and Microformats cover all the worthwhile relationships in that already.

These are covered by HTML5 already:

  • permalink -> bookmark
  • archive -> archives
  • feed
  • pingback
  • unendorsed -> nofollow

The rest now seem unnecessary.

Nonetheless, there may be some mileage in using them in microformats, at least until HTML5 is widely available.

abandonnées

The following rel values were in earlier version(s) of specification(s) and it is presumed by their absence from the most recent version of the respective specification(s) that they have been deprecated or obsoleted. Use of them could be considered a bit more standard than just POSH, although you may wish to research why such values were omitted from latter specifications before using them. If you do discover the reasoning, please add a short statement or link to thereof into the appropriate place in the following table.

Sources: HTML3 (expired!) - (has been superceded by HTML 3.2 - which itself has been superceded by HTML 4.0 - which itself has been updated by HTML 4.01, commonly referred to as "HTML 4" in this wiki and other places.)

banner Was used to reference another document to be used as banner for this document (i.e. a form of "include" statement). HTML 3 unknown
up When the document forms part of a hierarchy, this link references the immediate parent of the current document. HTML 3 unknown, but proposed for re-introduction in HTML5


rejetées

Some rel values have been proposed and rejected. These are not recommended for use, and listed here to make that explicit.

Source : formats-rejetés.

value rel origine / proposition pourquoi rejetées
pavatar pavatar rejected-formats#Pavatar


non spécifiées

Some rel values have been added to this page perhaps in one of the tables above, but no examples, nor an actual specification explicitly stating that the value(s) should be used in the HTML4 'rel' attribute could be found. They are listed here in the hopes someone can discover more specific/precise URLs to examples or specifications about them (preferably both). Until such precise URLs to examples/specs are provided, the values can be treated as they are purely theoretical and thus of little interest.

value rel résumé source possible
schema.DC Dublin Core
schema.DCTERMS Dublin Core

Notes :

  • Dublin Core. Cette recherche peut aider : [5]. At first glance it appears the results from the search show only uses with the invisible <link href> element which is not ideal for content relationships. Content relationships should be user visible and thus uses with <a href> are strongly preferred. Unfortunately the use of Dublin Core in user visible content like <a href> appears to be strictly theoretical.
