An application in Oracle Commerce Experience Manager must have at least one site, and every site in the application must have its own site definition.

In a multiple site application, the properties in a site definition determine site-specific behavior. The site definition can be a JSON file located in the /<app_name>/config/import/pages/<site_ID> directory for your application. This JSON representation of a site definition is what you see in a deployment template or if you were to export the site after it is deployed. You can modify a site definition in this form and import it to update the JCR's site definition node. For example, a Discover Electronics application might have a site definition in the /Discover/config/import/pages/DiscoverElectronics directory.

{
    "ecr:type":"site-home",
    "urlPattern" : "",
    "displayName":"DiscoverElectronics",
    "description" : ""
}

Note that all properties in JSON files including the site definition must be in UTF-8 character format. Convert all Unicode characters to JSON encoded values. The properties of this file are described in the next section.
