The Interoperability Toolkit (ITK) is a set of common specifications, frameworks and implementation guides. It supports interoperability within local organisations and across local health and social care communities.
In some areas, there's a good level of similarity in business process, data requirements and technical alignment. In others, there are competing and, in some cases, incompatible solutions.
The ITK attempts to solve these problems by providing a number of specifications and technologies which are consistent and applicable across a wide range of domains and localities. It's not a piece of software or a downloadable product.
