+          <p>A possible approach to implementation is for publishers to configure a Web Service that provides a connection so as real-time data is received by the web service it can be instantly made available to consumers by polling or streaming. </p>
+
+          <p>If data is checked infrequently by consumers, real-time data can be polled upon consumer request for the most recent data through an API.  The data publishers will provide an API to facilitate these read-only requests.</p>
+
+          <p>If data is checked frequently by consumers, a streaming data implementation may be more appropriate where data is pushed through an API.  While streaming techniques are beyond the scope of this best practice, there are many standard protocols and technologies available (for example Server-sent Events, WebSocket, EventSourceAPI) for clients receiving automatic updates from the server.</p>
