The academic paper “Conceptualizing legal change as ‘norm-knitting’ through the example of the environmental human right” by Dorothea Endres in the Leiden Journal of International Law, 2023; 36(4) offers knitting as an extended metaphor for how international law is made, using the example of environmental law.
She maps needles to the actors, the pattern to norm types, tension as loose / tight norms, wool as resources, shape as the norm’s form, and colors as origins. While this is not, strictly speaking, data, it is a framework where one could model data from specific instances of successful or unsuccessful law-making, and the paper includes images of what the results would look like as these properties change.
