Strictly speaking, even a metadata schema such as EN 15907 is a vocabulary. It provides us with names and definitions of entities. In addition, it defines ways in which these entities can be combined in order to create meaningful statements. This is its role as a syntax definition.
In a syntax definition (also known as grammar), each element denotes a class of vocabulary items. In cases where the element has the syntactical role of a noun or adjective, this class will be referred to as type vocabulary. If the class members are expected to be verbs or verb phrases (including all constructs containing the verb to be), then we speak of a relationship vocabulary. And finally, where the element denotes a class of named entities (e.g. persons, product names, etc.), we use the term name authority file, a concept borrowed from librarianship.
