We are already receiving reports that some of the new networks are using proprietary interfaces to limit competition.

The definition of Interoperability isn't found in many dictionaries. The ability of two or more systems to interact in concert with one another in accordance with a prescribed method in order achieve a predictable result.

Interoperability implies compatibility among systems at specified levels of interaction.
This compatibility is achieved through specifications for the Interfaces between systems. Here is the current language for Sec. TAP-INFO reports on TAP activities relating to federal information policy.
