Web Services Dynamic Discovery protocol (WS-Discovery) is a standard mechanism for locating services and service endpoints in a SOA. The simplest and most common scenario for WS-Discovery is a Web Services client searching for one or more target services. WSO2 Carbon provides a complete implementation of the WS-Discovery managed mode. Therefore Governance Registry is also WS-Discovery compliant.
With WS-Discovery components for WSO2 Carbon, any Carbon server can act as a WS-Discovery client, a WS-Discovery proxy or a WS-Discovery target service. Discovered services and related metadata are stored in the Governance Registry. Therefore such information is also accessible via the service governance UI .
The Governance Registry aspect of WS-Discovery is further explained in the scenario explained at WS-Discovery with Governance Registry .
