Notes

ISO 19115-1 is a UML* representation that specifies the content, conditionality, and interrelations of the data documentation elements.

ISO 19139-3 is an XML** implementation of ISO 19115-1 and specifies metadata record format.

*UML (Unified Modeling Language) is a general-purpose modeling language in the field of software engineering, which is designed to provide a standard way to visualize the design of a system. It was created and developed by Grady Booch, Ivar Jacobson and James Rumbaugh at Rational Software and has since been adopted as a standard by the Object Management Group (OMG) — which has managed it since. The UML was also accepted by the International Organization for Standardization (ISO) as an approved ISO standard. Since then it has been periodically revised to cover the latest revision of UML.

** XML (Extensible Markup Language) defines a set of rules for encoding documents in a format which is both human-readable and machine-readable. Although the design of XML focuses on documents, it is widely used for representation of arbitrary data structures - such as those used in web services.
