This resource is a collection of all the items that have been uploaded to the server.
There are two ways to upload items. You can upload complete items using the Upload Item operation. If a particular item is made up of many chunks ( parts), you need to first register the item and subsequently upload the individual parts using the Upload Part operation. Item uploads are filtered by a whitelist of filename extensions. This is the default list: soe, sd, sde, odc, csv, txt, zshp, kmz. The default list can be overridden by setting the uploadFileExtensionWhitelist property with the server properties API.

Values: html | json
