Observing trends in publications related to ontologies and ontology Engineering, they look like most of them, if not all, are application oriented.Even more, when analyzing relatively recent history of this field, one can realize that, for example, during the first decade of the XXI Century, there was an intensive process of looking for new methodologies, and after creation of NeON Methodology, I feel, roughly speaking, nothing more has happened.
Other examples, from the development tools. Several years ago there were several tools competing for the roll of most used editor. Today looks like almost every thing is developed using Protégé. Regarding ontology languages there is a similar "state-of-affairs", even we try to open a debate around that topic last year: https://www.researchgate.net/post/What_are_the_current_trends_in_ontology_languages
What do you think? Hopefully I am wrong...
