The JSON-LD Working Group published today a First Public Working Draft of YAML-LD 1.0. [JSON-LD11] is a JSON-based format to serialize Linked Data. In recent years, [YAML] has emerged as a more concise format to represent information that had previously been serialized as [JSON], including API specifications, data schemas, and Linked Data.

FWIW, I have been storing Linked Data (including ActivityPub) in an INI like format — because I find INI-like formats more human-friendly (to both read and write) than JSON.

YAML is probably better than JSON, too, in that respects. But I think INI-like formats are better than YAML.
