ECCU File Structure and Digital Properties
The ECCU file structure, used in the Enhanced CCU, ECCU file upload, and PublishECCU, is discussed in Enhanced CCU Request Format. The ECCU file is an XML structure that allows you to specify the rules by which content will be refreshed. For PublishECCU and ECCU file upload, you create ECCU files, while in the ECCU you specify the properties in the browser UI but can then view the ECCU structure which is created for you by the Web interface.
When you work with the ECCU structure, you work with digital properties, digital property types, and exact/inexact matches. These are described in About Digital Properties.
