Models as the subject of research.

The focus remained on the development of software, but because software usually is embedded in a social, technical, or business context, various domains inside and related to informatics were more deeply involved. The above questions were discussed not only for the UML standard, which had at that time become relatively stable (and incomplete in terms of practical adoption, with many existing UML tools only partially satisfying many of the users needs). We can safely state that since the early UML discussions at OOPSLA in the 1990s and the start of the MoDELS/UML series of conferences, models and modeling languages have become the subject of study of research on their own, leading to hundreds of Ph.D. dissertations across the world.
