Vocabularies used into datasets

"Typically a value vocabulary define concepts related to described resources (persons, languages, countries, etc.). They are "building blocks" with which metadata records can be populated.
A value vocabulary thus represents a controlled list of allowed values for an element. To be useful for linking of data, value vocabularies should have HTTP URIs assigned for each value; these URIs would then appear in a metadata record instead of or in addition to the literal value."
