Center node: "thinging vs objectfying in software engineering"
  Abstract: In this paper, we propose the use of a modeling methodology based on the notion of thing, with a focus on the current stage of research being on the analysis phase of software system modeling. The object-oriented approach, which takes the object as a central concept, provides the opportunity to explore applying thinging to the reconceptualization of objects. Several object-oriented examples are recast in terms of thing-oriented modeling. The results indicate a positive development that leads to several possible options: (1) supplementing the object orientation (OO) paradigm with additional notations, and (2) promoting a further understanding of some aspect of the OO paradigm. The possibility of developing a new approach in modeling based on thinging also exists.
