Can temporal conceptual modelling be useful in industry?

TL;DR: yes, and for sure in public procurement. More generally, the temporal database developers probably will see a place for temporal conceptual modelling since there are a good number of temporal databases that need to be designed and there are SQL features for it, notably since SQL:2011 for temporal SQL [1]. Advanced conceptual modellers and logicians pine for a resounding ‘yes’ to the post title’s question. Why would they hope so? Several temporal conceptual modelling languages and corresponding logics have been proposed over the decades, but none has been tested in industry yet, other than MADS’s avalanche use case 20 years ago [2], and one of my students had small focus groups over 10 years ago for his Masters research, which contributed to the development of the TREND language [3,4]. TREND was tested extensively (>1000 participants in 11 experiment), but on toy domains or models, and mostly with students [4]. We needed something bigger and more impactful. Enter public…
