under Attribute
A property or characteristic of a computing product. CPE 2.2 commonly used the term “component” instead of “attribute”. CPE 2.3 uses the term “attribute” to clarify the distinction between CPE:2.2 name “components” and computing components, such as software modules. Examples of CPE:2.3 attributes are part, vendor, product, and version. CPE attributes and their value constraints are defined in the CPE Naming specification [CPE23-N:5.2, 5.3].
