item

An item, also known as a content item, is a resource stored in a portal such as web maps, layers, styles, script tools, files, and notebooks. An item is used to manage the properties (metadata) and settings of a resource, and they are accessible both through an item page and ArcGIS APIs. Properties such as name, owner, title, description, created (date), tags, and sharing settings can be set through the item page. To access an item, you can reference it by its URL or unique item ID.

An item is created when:

• A file is added to a portal.
• A URL to a resource is referenced.
• A result is produced from the completion of an analysis tool.
• Using the Map Viewer and interactive tools.

Configuring the sharing level of an item will ensure the security of the item and its underlying data. The following is a list of the sharing levels available for the different types of ArcGIS products:
