Types MIME

Le type d'extensions de courrier électronique multi-utilisateur (MIME- Multipurpose Internet Mail Extension) est une spécification pour la transmission sur le réseau de fichiers de différents types: images, musique, textes, vidéos, archives, etc. Le standard du type MIME est IETF RFC 6838.

La spécification de type MIME est utilisée en HTML généralement lorsque les données du formulaire sont transférées et insérées dur la page de divers objets. Les navigateurs utilisent souvent le type MIME (et non l'extension de fichier) pour déterminer comment il va traiter le document.

La syntaxe

Type/sous-type

Une structure de type MIME consiste en un type et un sous-type séparé par une barre oblique (/) sans espace. Le type MIME n'est pas sensible à la casse, mais il est généralement écrit en minuscule.

On distingue deux types: discret et multi-usages. Chaque type a ses sous-types.

Types discrets

text/plain
text/html
image/jpeg
image/png
audio/mpeg
audio/ogg
audio/*
video/mp4
application/*
application/json
application/javascript
application/ecmascript
application/octet-stream
…

Le type discret indique la catégorie d’un document. Les variants possibles ci-dessous.

Type Définition Exemple de sous-type
application Contient données binaires application/javascript, application/octet-stream,
application/pkcs12,
application/vnd.mspowerpoint,
application/xhtml+xml, application/xml,
application/pdf
audio Fichier audio audio/midi , audio/mpeg, audio/webm,
audio/ogg, audio/wav
image Images, y compris des animées (gif) image/gif, image/png, image/jpeg, image/bmp,
image/webp, image/x-icon,
image/vnd.microsoft.icon
text Document de texte text/plain , text/html , text/css, text/javascript
video Vidéo video/webm , video/ogg

Pour la description des documents de texte, qui n’appartiennent pas à un sous-type particulier, on utilise text/plain. Les documents contenant des données binaires sans sous-type spécifique sont décrits en utilisant application / octet-stream.

Types multi-usages

multipart/form-data
multipart/byteranges

Les types multi-usages indiquent la catégorie d’un document composé de plusieurs parties, chaque partie pouvant appartenir à différents types MIME.
