+# Module `share`
+
+Ce module permet partager des ressources à destination des autres applications exécutées dans l'environnement Edge.
+
+## Propriétés
+
+### `share.ANY_TYPE`, `share.ANY_NAME`
+
+Les propriétés `share.ANY_TYPE` et `share.ANY_NAME` sont utilisées dans la méthode `share.findResources()` pour récupérer ne pas appliquer de filtre spécifique au type ou au nom des attributs respectivement.
+
+### `share.TYPE_TEXT`, `share.TYPE_NUMBER`, `share.TYPE_PATH`, `share.TYPE_BOOL`
+
+Ces propriétés correspondant aux types d'attributs possibles dans une ressource.
+
+Le type `share.TYPE_PATH` décrit un "chemin" destiné à être transformé en URL par l'application consommatrice de la ressource sous la forme `${APP_URL}${PATH}`. Ce type d'attribut peut être utilisé pour partager des URLs (médias, pages, etc) entre applications.
+
+## Méthodes
+
+### `share.upsertResource(ctx: Context, resourceId: string, ...attributes: Attribute[]): Resource`
+
+Cette méthode permet de créer une ressource ou de la mettre à jour si elle existe déjà. Elle prend en paramètre le contexte d'exécution, l'identifiant de la ressource et une liste d'attributs. 
+
+Si la ressource n'existe pas, elle sera créée avec les attributs fournis. Si elle existe, les attributs existants seront mis à jour avec les valeurs fournies.
+
+#### Arguments
+
+- `ctx: Context`: Le contexte d'exécution.
+- `resourceId: string`: L'identifiant de la ressource.
+- `...attributes: Attribute[]`: Une liste d'attributs. Chaque attribut est représenté par un objet de type `Attribute`.
+
+#### Valeur de retour
+
+La méthode retourne un objet de type `Resource` qui représente la ressource créée ou mise à jour.
+
+#### Usage
+
+```javascript
+const resource = share.upsertResource(ctx, "my-resource", { name: "color", type: share.TYPE_TEXT, value: "red" });
+console.log(resource);
+// Output: { id: "my-resource", origin: "my.app", attributes: [{ name: "color", type: "text", value: "red", createdAt: "2023-04-21T14:30:00Z", updatedAt: "2023-04-21T14:30:00Z" }] }
+```
+
+### `share.findResources(ctx: Context, withAttribute?: string, withType?: string): []Resource`
+
+Cette méthode permet de rechercher des ressources en fonction de leurs attributs. Elle prend en paramètre le contexte d'exécution et deux paramètres optionnels qui permettent de filtrer les ressources.
+
+#### Arguments
+
+- `ctx: Context`: Le contexte d'exécution.
+- `withAttribute?: string`: (optionnel) Le nom de l'attribut à rechercher (`share.ANY_NAME` par défaut)
+- `withType?: string`: (optionnel) Le type de l'attribut à rechercher (`share.ANY_TYPE` par défaut)
+
+#### Valeur de retour
+
+La méthode retourne un tableau d'objets de type `Resource` qui représentent les ressources correspondant aux critères de recherche.
+
+#### Usage
+
+```typescript
+const resources = share.findResources(ctx, "color", share.TYPE_TEXT);
+console.log(resources);
+// Output: [{ id: "my-resource", origin: "my/app", attributes: [{ name: "color", type: "text", value: "red", createdAt: "2023-04-21T14:30:00Z", updatedAt: "2023-04-21T14:30:00Z" }] }]
+```
+
+### `share.deleteAttributes(ctx: Context, resourceId: string, ...names: string[]): Resource`
+
+Cette méthode supprime un ou plusieurs attributs de la ressource spécifiée.
+
+#### Arguments
+
+- `ctx: Context`: contexte d'exécution
+- `resourceId: string`: identifiant unique de la ressource à modifier
+- `...names: string[]`: tableau de noms d'attributs à supprimer
+
+#### Valeur de retour
+
+La méthode retourne un objet de type `Resource` qui représente la ressource modifiée.
+
+#### Usage
+
+```typescript
+const resource = share.upsertResource(ctx, "my-resource", { name: "color", type: share.TYPE_TEXT, value: "red" });
+console.log(resource);
+// Output: { id: "my-resource", origin: "my.app", attributes: [{ name: "color", type: "text", value: "red", createdAt: "2023-04-21T14:30:00Z", updatedAt: "2023-04-21T14:30:00Z" }] }
+```
+
+### `share.deleteResource(ctx: Context, resourceId: string)`
+
+Cette méthode supprime la ressource spécifiée.
+
+#### Arguments
+
+- `ctx: Context`: contexte d'exécution
+- `resourceId: string`: identifiant unique de la ressource à supprimer
+
+#### Valeur de retour
+
+La méthode ne retourne pas de valeur.
+
+#### Usage
+
+```typescript
+const resource = share.deleteResource(ctx, "my-resource");
+```
+
+## Objets
+
+### `Context`
+
+Voir la documentation du module [`context`](./context.md)
+
+
+### `Resource`
+
+```typescript
+interface Resource {
+    id: string
+    origin: string
+    attributes: Attribute[]
+}
+```
+
+### `Attribute`
+
+```typescript
+interface Attribute {
+    name: string
+    type: ValueType
+    createdAt: string
+    updatedAt: string
+}
+```
+
+### `ValueType`
+
+```typescript
+enum ValueType {
+    TYPE_TEXT = "text",
+    TYPE_PATH = "path",
+    TYPE_NUMBER = "number",
+    TYPE_BOOL = "bool"
+}
