Defines a protocol for metadata events. Metadata events hold metadata information about other events, or entities

Kind 34578 — Metadata Event#

Metadata events use kind 34578 (addressable). They are distinguished by their d tag and the presence of the ["t", "<sub_type>"] tag. The content of a metadata event always has a json which is encrypted to the author's pubkey. The shape of the json depends on the sub type of the metadata event

tag	value
d	depends on the sub-type of the metadata event
t	"<sub-type>" — sub-type of the event

  "tags": [

  ],
  "content": "<nip44-ciphertext of json encrypted to abc123>",
  "sig": "..."
