Extension: NDH Associated Servers

This extension enables NDH to represent endpoint-to-server associations so implementers can publish alternate or companion server routes for operational flexibility, with structured sub-extensions for server type and server URL and an extensible binding to NdhAssociatedServersTypeVS for consistent classification; it is used in Endpoint.

Context of Use

This extension may be used on the following element(s)

• Element ID: Endpoint

Usage info

Usages:

• Use this Extension: NDH Endpoint Profile
• Examples for this Extension: Endpoint for Acme of CT Portal and Endpoint for Coordination of Care
