Goal

“Enable development** of SCC applications with minimal effort by various stakeholders* involved in

development process”

**Development -- “a set of related activities that leads to a production of a software product.’’ [Ian Sommerville, Software Engineering (9th edition) , 2010]

*Stakeholders in software engineering to mean – people, who are involved in the application development. Examples of stakeholders defined in [Taylor et al., Software Architecture, 2009] are software designer, developer, domain expert, technologist, etc.

“Entities of Interest (EoI) is an object, including the attributes that describes

it, and its state that is relevant from a user or an application perspective.” [Stephan Haller, Internet of Things,

2010]
