UMLn
UMLn, short for Unified Modeling Language next, is a proposed extension to the UML family intended to help model complex, dynamic, and distributed software and systems. It maintains core UML concepts while expanding notation, semantics, and tooling to address runtime reconfiguration, adaptive behavior, and cross-cutting concerns such as non-functional requirements. UMLn is described in academic and professional discussions as a way to bridge modeling at design time with behavior observed at run time.
Core ideas include a set of extended diagram types, such as n-activity diagrams, n-sequence diagrams, and n-structure
Status: Not standardized. There is no official OMG standard for UMLn. Proposals remain largely experimental and
Impact and reception: In theory, UMLn could improve modeling of self-adaptive and cloud-native systems, complex event
