I really like the idea of plain text data files so am really interested in this.

YAML serves this purpose too but I'm not a huge fan of indenting so recfiles look great. Anyone compared and contrasted?

Also are there other resources on this? Would be nice to have Java/C++/Python libraries. (As well as convert to parquet, arrow etc )

I have done some prototyping on a similar idea, but I think with a more idiomatic approach. The idea is mostly adding relational structure (schema) to CSV, and enabling a cleaner lexical syntax (get rid of the line noise).

Might some day dust it off and try to bring it to a more serious level (performance, tooling etc).
