q2 i? In the per-dimension histograms, accessibility and complexity present the overall lowest restrictions, while popularity and architecture present the higher restrictions. → Valdés Aguirre 2016

This finding comes from the article's analysis section, based on per-dimension restriction histograms (Fig. 3) over the surveyed 2013-2014 student models. The authors interpret this as reflecting "the aspect in which SMs are more mature", with the community more concerned with making models available and understandable than with architectures and replication.

"In Fig. 3 we show the histograms for the restrictions of each dimension. At a first glance we can see that the accessibility and complexity dimensions present the overall lowest restrictions. Popularity and architecture present the higher restrictions."
