Data interchange standards

"Data interchange standards may help to define the interfaces onto which different metadata schemas can be transported across a wide variety of systems. Whatever technology is used, it must allow the information exchange to keep the original semantics and structure of the metadata. These standards offer a ‘neutral’ representation of the metadata elements and their arranged order. They are not concerned with the underlying semantics, only with providing a common, purely machine-readable way of carrying the defined elements across networks, systems and platforms. Data interchange standards thus establish the mapping interfaces between the definition layer and the technology layer of information systems."
