All records allow for storing arbitrary information in the "data" map:
type data_map =(string, bytes) map
map %data string bytes
All entries have:
A key that should have a unique meaning. There is a set of reserved keys for typical use, but users are free to create new keys.
A value which must be represented in JSON (RFC 8259) and encoded in UTF-8.
All keys with the prefix td: are reserved for Tezos Domains-related metadata. We currently recognize:
The time-to-live of the record and an associated reverse record, if any (in seconds). If defined, it specifies the maximum time the record should be stored in caches and other secondary-storage mechanisms.
The prefix openid: is reserved for OpenID claims. The values have their respective meanings according to the OpenID spec. The value types specified in the OpenID spec must be adhered to.
