Metadata Centralization (Erl)
How can service metadata be centrally published and governed?
Project teams, especially in larger enterprises, run the constant risk of building functionality that already exists or is already in development, resulting in wasted effort, service logic redundancy, and service inventory denormalization.
Service metadata can be centrally published in a service registry so as to provide a formal means of service registration and discovery.

The fundamental discovery process during which a human locates a potential service via a service registry representing the service inventory and then interprets the service to determine its suitability.
