A solution architecture template can exist at different levels of detail. For example, it can be used to describe a template for national portals offering e-services to its citizens. It can also be used to describe a template on how to securely exchange files among public administrations.

- A goal and a description of the particular supported business capabilities and the involved business information exchanges;
- A sub-set of EIRA© core Architecture Building Blocks covering all EIRA© views;
- A set of specific Architecture Building Blocks extending EIRA©'s views enabling specific functionalities to be provided by implementations derived from the SAT;
