Agent Profile Database?

Does anyone know of any instances or best practices for building database of agent profiles? This is coming freshly from Token Model Generation exercises we started in TE book/TE Academy:

it would be extremely valuable if we can document assumptions about agents, e.g. motivations, valuable assets (stocks), valuable capabilities (stock? diamond?..) relationships and motivations (flows) - but especially characteristics and motivations in one public DB on github, probably directly cadCAD repo, so that they can be scrutinized, improved, varied, by modellers, and domain ppl.

What is the best format? data model to use, such that these agent profiles are pluggable to any model& simulation specifically in cadCAD? I would like to give it a try and gain experience applying it alongside TE book work.
