NENA Releases Registry System Standard
When developing and deploying technical standards that employ enumerations, or lists of values, where the enumeration or lists can reasonably be expected to change over time as new technology, vendors, service providers or other stakeholders evolve, a known stable way to maintain the current acceptable values in the enumeration or list is required. The values in the enumeration or list are called a registry. This document describes how registries are created and maintained in NENA.
