Trucs hAtom

hAtom est un microformat pour le contenu qui peut être syndiqué, originellement mais pas exclusivement pour les billets de blogs. Cette page donne des astuces sur la façon d'utiliser, d'implémenter et embarquer hAtom, de l'historique et d'autres informations étroitement en rapport avec la spécification hAtom mais n'appartient pas strictement à la page principale.

S'il existe un conflit entre cette page et la spécification, la spécification est correcte.

Cette page est actuellement obsolète. Consultez la spécification du microformat en rapport pour une information à jour.


Notes de Schéma

Concept Atom Identifier hAtom Microformat Usage
Feed atom:feed Add class name "hfeed"
Entry atom:entry Add class name hentry; if practical, also define id="unique-identifier" to the Entry.
Entry Title atom:title Add class name headline. Using <h#> also is encouraged.
Entry Content atom:content Add class name content to all appropriate blocks. Multiple Entry Content blocks are logically considered one concatenated atom:content equivalent.
Entry Summary atom:summary Add class name excerpt to all appropriate blocks. Multiple Entry Summary blocks are logically considered one concatenated atom:summary equivalent.
Entry Permalink atom:link Add a rel value of bookmark.
Entry Published atom:published Use class name published, optionally with the datetime-design-pattern-fr.
Entry Updated atom:updated Use class nameupdated, with an ISO8601 absolute datetime, optionally with the datetime-design-pattern-fr.
Entry Author atom:author Add class name "author. Using an address element is recommended. A hCard SHOULD be added.

hAtom Opaque

"hAtom Opaque" specifies whether a hAtom parser should not "look inside" the element for further hAtom content. If there are multiple rules applied to the same element take the OR of the two (i.e. "Yes/Opaque" always wins)

hAtom Opaque is designed to make parsing rules less ambiguous. In particular, it allows "quoted" hAtom elements (from another blog being blockquoted, for example) ti be ignored. It also allows 'embedded' hAtom to be potentially delivered within hAtom itself, and to prevent accidental 'leaking' of other microformat information up into the hAtom container. A general concept of opaqueness (need link) has also been proposed but it will complement, not replace this.

How many times can an element of the given type appear in it's nesting/parent element.

Cardinalité Logique

This column is informative -- Atom has a number of rules for deciding what is required depending on the context and other elements, many which aren't strictly applicable to here.

From a modeling/logical perspective, the number of times can an element appear.

This is all rule dependent, see below. For example, an Entry Permalink may appear 6 times, but each one must be the same value; an Entry Content element may appear 3 times, but they are all concatenated together to make a single logical element.

Element notes

Entrée Permalink
The intention of the previous two rules to gently force people to use strings that can be byte compared for equivalence. In general, the canonical URI should be the link used in an Atom entry.
