Abstract: Various embodiments described herein relate to foundation applications comprising a framework which can be extended to provide a domain-specific application. In this regard, a foundation application comprising a plurality of predefined core services is generated. An extension request is received that comprises an addition or modification to data associated with a selected template. In response to the extension request, output data is determined based on the addition or the modification to the data associated with the selected template. A visualization comprising an indication of the output data is provided at an electronic interface of the foundation application.
