RSS <guid> Element

Complete RSS Reference

Definition and Usage

The <guid> element defines a unique identifier for the item.

Tips and Notes

Note: Aggregators must view the guid as a string. There are no rules for the syntax. It's up to the creator of the RSS document, to establish the uniqueness of the string.

Tip: GUID = Globally Unique Identifier.

Attributes
