== Abstract ==
RelPayment is a microformat for making exchanges of support (be it financial or otherwise) possible. By adding rel="payment" to a hyperlink a page indicates that the destination of that hyperlink provides a way to show or give support for the current page. For example to give financial support to the owner of the current page.
 
One of the goals with this microformat is to give content aggregators such as RSS readers a way to extract these support links and give them special attention (such as displaying a standard button along with the content).
 
== RelPayment ==
RelPayment est pensé comme un moyen général de faciliter les actes de donation, et de ce fait cette spécification de fait aucune hypothèse sur le type de support.
 
Une page peut contenir n'importe quel nombre d'hyperlines marqués avec rel="payment". Ceci permet aux auteurs de donner aux lecteurs plus d'un moyen possible d'afficher le support pour la donation (un lien DropCash, un lien PayPal, un lien vers une page avec une adresse pour envoyer un chèque et ainsi de suite.) Cela permet aussi aux auteurs d'ajouter des liens de paiement qui ne sont seulement en rappoert qu'avec une certaine section de page. Par exemple un site web de critique de livre peut avoir plusieurs critiques de livres sur une page avec chaque critique ayant son propre lien Amazon Affilié balisé avec rel="payment". Les agrégateurs devraient implémenter le support pour plusieurs hyperliens de paiement.
 
Les auteurs devraient utiliser l'attribut "title" pour fournir une description lisible par un humain du type de support pointé par l'hyperlien. Les agrégateurs peuvent utiliser les contenus de l'attribut "title" pour fournir une information additionnelle à propos deu lien support vers leurs utilisateurs. Par exemple <a href="[url]" rel="payment" title="Donnez de l'Argent Via  PayPal">.
 
Si l'hyperlien contient une image (par ex. <a href="[url] rel="payment"><img src="[url]" alt="Badge de Support" /></a>) les agrégateurs peuvent afficher cette image au lieu du lien standard de l'agrégateur.
 
== Métadonnée Visible  ==
Les liens balisés avec rel="payment" sont sensés être visibles sur la page, et ce parce que l'élément <a> est encouragé sur l'élément <link>. Ceci donne aux lecteurs l'accès le plus facile pour montrer le support et cela décourage la fraude de lien. Les auteurs ne devraient pas utiliser des hyperliens vide tels que <a href="[url]" rel="payment" /> et les parseurs peuvent ignorer les liens vides.

=== Enregistrement ===
 
http://www.iana.org/assignments/link-relations
 
=== Valeur d'Attribut ===
 
"payment"
 
=== Description ===
 
rel="payment" indicates a URI where payment is accepted. 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 WWW page where donations
are accepted or where goods and services are available for purchase.
rel="payment" is not intended to initiate an automated transaction.
 
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.
 
=== Caractéristiques d'Affichage ===
 
End-user software could support rel="payment" by displaying a "payment
button" along with the content. Alternatively, content aggregators may
display a payment hyperlink containing the text specified in a
corresponding title attribute within the <link> element, for example:
<pre>
<link rel="payment"
    href="http://example.com/c.r.e.a.m"
    title="give me the loot" />
</pre>
May display either a payment button or a hyperlink containing the
text, "give me the loot."
 
=== Considérations de Sécurité ===
 
The link element is subject to tampering and observation, as is the
linked resource. For that reason, implementations should clearly
signal the level trust and privacy a linked resource provides.  If
present, digital signatures provide authentication, message integrity,
and non-repudiation with proof of origin. Encryption provides data
confidentiality. Implementations should also consider the level of
confidentiality and message integrity provided by the transport used
to reach the payment resource.

=== Proposition d'Anil Dash, 2002 ===
 
* http://www.dashes.com/anil/2002/12/10/payment_link_ta
 
Anil Dash's proposal in 2002 to use XHTML <link> element to define payment URLs:
 
<blockquote>
<b>payment LINK tags</b>
<br/>
There are already a lot of defined (if not quite standardized) possible values for the LINK element in XHTML. We're using them for RSS Auto-Discovery and, of course, for stylesheets already. But what about something like:
<br/>
<link rel="appendix" type="text/html" title="payment" href="URL of Wishlist or Paypal Page" />
<br/>
A standardized way of linking to the page where you pay for your patronage of a site. Granted, calling the payment page an "Apppendix" of the site you're visiting is fudging things a bit. Maybe there's a more elegant way?
</blockquote>
 
Although this is similar to rel="payment" as we are proposing, it is not as flexible as it can only be used to define one payment location for an entire page (likely a tip jar or wishlist page). Perhaps rel="payment" could be used within the link element as well as within standard anchor tags?
