## Kinds ## Kinds
The `.kind` attribute specifies the meaning of an event, its tags and it is further defined in the various NIPs in this repository The `.kind` attribute specifies the meaning of an event and its tags.
Specific ranges define storage behaviors: Kinds are grouped in 4 numeric ranges to provide explicit storage behaviors for clients and relays:
- Regular: All events are stored in disk and will last for as long as possible.
- Ephemeral events are to be discared as soon as processed. They are ideal to send commands that should be executed immediatedly or not executed at all.
- Replaceable events can be quickly updated by newer versions. They are ideal for status events that are always changing and the history of such changes is not important.
- Parameterized replaceable events extend replaceable kinds to offer an extra identifier as the replacement anchor

This NIP defines the format of 3 standard referencing tags: `e`, `p`, and `a`. Tags `e`, `p` can be used to reference events and pubkeys respectively, and tag `a` references the latest version of a replaceable event. Clients MAY `a`- and `e`-tag parameterized replaceables simultaneously. This NIP defines the format of 3 referencing tags: `e`, `p`, and `a`.
