From Science Europe Data Glossary
Definition: data interoperability is the ability of making the data systems of organizations work together.
Explanation: while the term was initially defined for information technology or systems engineering services to allow for information exchange, a more broad definition of interoperability takes into account social, political, and organizational factors that impact system-to-system performance. Data interoperability ensures that data can be used across systems and understood by different persons. It usually involves one or more forms of standardization, including the use of metadata standards.
