If two or more systems use common data formats and communication protocols and are capable of communicating with each other, they exhibit syntactic interoperability. XML and SQL are examples of common data formats and protocols. Lower-level data formats also contribute to syntactic interoperability, ensuring that alphabetical characters are stored in the same ASCII or a Unicode format in all the communicating systems.

Beyond the ability of two or more computer systems to exchange information, semantic interoperability is the ability to automatically interpret the information exchanged meaningfully and accurately in order to produce useful results as defined by the end users of both systems.

Cross-domain interoperability involves multiple social, organizational, political, legal entities working together for a common interest or information exchange.
