The technologies and services cover the following areas

All of these services have live and development deployments and are free to access.

They all operate in three ways:

User of Web APIs for systems to interoperate so that the resources can be used as part of an integrated offering
Local implementations whereby local code APIs are used instead of Web APIs.

These technologies form part of a broader set technologies, many of which have been used by a large scale NHS London Data linkage and normalisation Service Known as Discovery, covering a population of 7 million registered citizens.
