If two or more systems use common [[File format|data format]]s and [[communication protocol]]s then they are capable of communicating with each other and they exhibit ''syntactic interoperability''. [[XML]] and [[SQL]] are examples of common data formats and protocols. Low-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. To achieve semantic interoperability, both sides must refer to a common information exchange reference model. The content of the information exchange requests are unambiguously defined: what is sent is the same as what is understood.

[[Cross-domain interoperability]] involves multiple social, organizational, political, legal entities working together for a common interest or information exchange.<ref>Slater, T. {{usurped|1=[https://web.archive.org/web/20160826110009/https://www.ncoic.org/cross-domain-interoperability "Cross-Domain Interoperability"]}}, {{usurped|1=[https://web.archive.org/web/20130506134432/https://www.ncoic.org/home ''Network Centric Operations Industry Consortium - NCOIC'']}}, 2013</ref>
