System Attributes
System attributes represent the different types of metadata that scanners extract from source systems. For example, Author is a system attribute of the String data type that you can assign to a resource. You can configure these predefined attributes in Catalog Administrator.
You can use system attributes to filter the search results that you are looking when you use Enterprise Data Catalog to search the metadata. Use the Catalog Administrator to configure the search ranking of a system attribute based on the requirement. You can also set up the system attribute so that Enterprise Data Catalog includes the attribute in search filters.
