Features of a central component

With the interoerpability layer being a central component of the health information exchange there are a number of features that present themselves. Some of these are positive features and other are negative features. These are listed below:

• Certificate management is centralised, this allows for easier management and setup.

• Domain services don’t have to all implement functionality to audit, log and authenticate message thus making them simpler.

• Allows messages to be easily intercepted for secondary use which is benaficial to enable additional functions as the HIE grows.

• Could be a dependency knot when other services have to join the exchange as this central component will have to be configured for each change - can be mitigated by allowing simple pass through of web services via configuration, thus the changes are in configuration only.
