A SWOT analysis of the object constraint language

The Object Constraint Language (OCL) is a textual language to describe constraints or queries over software models defined by applying the Unified Modeling Language (UML). Using OCL, it is possible to specify, for instance, integrity constraints in the form of class invariants, operation pre-conditions, or post-conditions. This paper presents a SWOT analysis (Strengths, Weaknesses, Opportunities, and Threats) of OCL, considering both its current state and future perspectives: specification, tool support, applications, competitors, and the community around it. This analysis was the result of the panel discussion at the 20th International Workshop on OCL and Textual Modeling (OCL’21).
