Description

Im impressed by the progress. Since Im finalizing the posteriordb beta, I realized that it would be good to formalize also how a posterior is represented as json. This would also enable cross-language representations.

Have you thought about this?

I currently represent draws as a named object of numeric arrays. Think a named list of a vector in R, with one vector per parameter.

Research direction

The issue names no files, tests, or entry points. Start by reviewing how posterior draws are currently represented in the R package, then clarify the proposed JSON schema and cross-language requirements; done would require an agreed formal representation, but the issue does not define acceptance criteria.
