Configuration de la diffusion
La configuration centralise toutes les informations nécessaires à la diffusion de données sur les services. A ce moment, on va contrôler les paramètres et détecter les erreurs ou conflits potentiels :
- nom de couche déjà pris (il doit y avoir unicité sur toutes les configurations DOWNLOAD de la plateforme)
- doublon dans le nom des sous-couches (si on veut diffuser plusieurs données ARCHIVE au sein d'une même configuration)

Si on ne précise pas de titre ou de résumé pour la donnée stockée diffusée, ce sera son nom qui sera utilisé. Les codes des langues sont ceux ISO-639-1.
Dans les sous-ressources, format
, zone
et resolution
(non utilisé ici) s'appuieront sur les nomenclatures pour afficher au niveau du service de téléchargement des noms plus humains. On fournit ici les term
et les label
seront ajoutés. Si la valeur dans la configuration ne correspond à aucun term pour le type correspondant, le label prendra la même valeur. Le SRS de la donnée stockée sera également enrichie en utilisant la nomenclature. Dans le service de téléchargement, le term
sera convertit en URL pour respecter les specifications Atom.
Voici un exemple pour voir la nomenclature des zones :

Publication
À ce stade, aucune information n'a été envoyée aux serveurs de téléchargement assurant la diffusion. Cette synchronisation de la configuration sur les serveurs de diffusion, représentés par le point d'accès, se fait via la création d'une offre : la publication. Elle matérialise la présence d'une configuration sur un point d'accès.
