just thinking about infrastructure and, if "it's infrastructure all the way down," where we might draw lines between structure and infrastructure, and the infra- prefix which, like the meta- prefix, denotes an ambiguous or undecidable relatinship or positionality: where is the infra? below? within?
so if data requires or entails metadata, does structure require or entail metastructure? since metadata is "about" data (and "about" signals kaleidoscopically), then metastructure would be "about" structure
