GetServices
From Exchange Network Wiki
The GetServices method is a key function (or "web method" for Exchange Network nodes. It allows requesters to query services provided by a Network Node. The type of services that can be queried includes, but is not limited to:
- Interfaces: The Web service interfaces supported by the Node.
- Query: Predefined information requests that can be used in the Query method.
- Solicit: Predefined information requests that can be used in the Solicit method.
- Execute: Predefined procedures that can be used in the Execute method.
A Node may choose to support additional types (meta-data) when needed. To get a complete list of all service types, a requester can pass ServiceType as the value of the ServiceType element.
Using GetServices, a requester can determine the capability of a Node at runtime and proceed accordingly. On the other hand, it allows the service provider to extend the services provided, (e.g., add a new database report), without changing the infrastructure. The smart invocation and easy extensibility can greatly enhance the overall usability, stability and capability of the Exchange Network.
