Interoperability refers to the ability of systems, whether technical or organizational, to work together smoothly through common standards and protocols. This concept ranges from syntactic communication between software using XML to cross-border e-government services and military coalition operations.
Authors such as Carl Malamud point out its visible presence in global networks, while the European Union highlights its role in integrating infrastructure. Eben Moglen emphasizes open standards like XML as essential for fostering interoperability, balancing technical design with collaborative efforts. In the end, interoperability connects technical specifications with shared objectives, ensuring systems operate effectively across various fields.
