Registry of Controlled Vocabularies
External CVs are lists (or standards) defined by organizations, or referring to content, not within the control
of MDDL.org. Examples include the relevant ISO standards as well as identifiers provided by third party
organizations. Every effort is made to keep this list current but the definitive content is defined by the
respective owners.
Internal CVs are lists which MDDL.org has defined to facilitate the description of market data. These lists are
controlled by MDDL.org and maintained here as a reference. Note that this website is not intended for support
of production systems wishing to validate content - please make a cache or mirror within your production environment
should you require that level of access.
