Detailed Description

The Portal type is the main entry point into the API used to work with portals and organization subscriptions. It implements all the operations to interface with the backend ArcGIS REST API. Use Portal to search for items and groups and see the contents of the portal, such as services, layers, and so on.

Portals allow users and organizations to publish and share content over the web. A portal can support subscriptions which provide organizations a sandboxed area on the portal. The website www.arcgis.com (ArcGIS Online) is an example of a portal.

Organizations

A Portal may contain multiple organizations. An organization has users in different roles including administrators, publishers, and other users.

  • Administrators can add users to their organization subscriptions and have access to all content within the organization.
  • Publishers within an organization can in addition create hosted services based on data files that they upload.
  • All users can create web maps based on mashing up services that they have access to and can register services running on external servers.

Content

Users create and share content that organized into Items. A Portal can contain different types of content items including:

  • Web maps
  • Map services (that can be used as layers in web maps)
  • Applications (that are built around web maps)
  • Data files (that can be uploaded and downloaded)

Users can choose to keep the content they create private, or share it with other members of the same group, or make content public and accessible to everyone.

Users and Groups

A user of the Portal sees the view of the Portal that corresponds to their organization's subscription. This view includes users, groups, and items that belong to the organization or have been shared with them. This view may also include users, groups, and items that are external to the user's organization and have been shared with the user. A Portal can have users who are affiliated with an organization or users who are not.

Users can create and join groups.

Example: Create a portal anonymously:

Portal {
    id: agolAnon
    url: "http://www.arcgis.com"
}

Example: Create and load a portal with a credential:

Portal {
    id: agolAsNamedUser

    credential: Credential {
        username: myUsername
        password: myPassword
    }

    Component.onCompleted: load();

    onErrorChanged: {
        if (loadStatus === Enums.LoadStatusFailedToLoad)
            console.log(error.message);
    }
}

This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
