Create and manage tag properties
Tag properties describe, define, and annotate tags. They include business properties and technical properties. Business properties are typically defined by the users who request the tags and provide standard descriptions of application scenarios and business specifications. Technical properties are typically defined by developers and provide standard descriptions of information, such as tag calculation logic, data sources, and value types. This topic describes how to create and manage tag properties.
Prerequisites
