Extending iStar2.0 metamodel to define data structures

iStar2.0 provides a recommendation for the core constructs defined in the i* language, which are articulated around a metamodel. When applying iStar2.0 to a particular domain, it can be necessary to extend this metamodel in order to represent more specialized concepts. One of these domains is that of data structures, as implementation of abstract data types. In this paper, we build upon previous work on using i* to describe data structures from an intentional point of view, by introducing new constructs in iStar2.0 and adding them to the iStar2.0 metamodel. We illustrate the approach using some well-known abstract data types (sequences, functions, …) and the data structures implementing them (linked lists, heaps, hash tables, …).Peer ReviewedPostprint (published version
