What is a metadata item in Salesforce?

A metadata item in Salesforce refers to a representation of a Salesforce metadata type. Metadata in Salesforce essentially describes the structure and configuration of the system, such as custom objects, fields, page layouts, and workflows. Each of these elements constitutes a metadata type, and a metadata item is a specific instance of that type (for instance, a particular custom object or field created in the Salesforce environment).

Understanding this is crucial for managing Salesforce effectively because it helps in deploying and organizing changes in a controlled manner, especially in development and production environments. The focus on the configuration and structure—rather than specific data entries or analysis tools—is what defines the concept of metadata in the context of Salesforce.

This highlights the importance of a solid grasp of metadata in Salesforce as it underpins many administrative and development tasks, including deploying changes via change sets or utilizing tools like Copado for version control and continuous integration.
