Glossary

Warning, many of these entries added by a new user whilst attempting to get to grips with GUN:

_

A reserved field in a gun node object acting as a key for the node's metadata. E.g.

        "_" : { ... }, // meta data object
        ...
    } //node object```


#### `#`
1. Symbol used to denote a node's soul in a node's metadata object.
2. Symbol used to enter frozen space, roughly "the following is a hash, data got from this context should match it"
3. Symbol used to denote a gun reference when acting as a key in a node's object

#### `>`
Symbol used to denote a node's metadata in the node's object.

#### `~`
Symbol used to say "the following represents an public key"

#### `@`
Symbol used to say that "the following text is an alias to a public key"

#### Graph
An object that contains unique nodes.

#### Mesh
A collaborative network where each peer is responsible for forwarding others' messages (and responding to requests if it has the data). Refers to the concept of a [mesh network](https://en.wikipedia.org/wiki/Mesh_networking).

#### Node
An object within a graph. It can contain primitive values, but not other objects (only pointers to other nodes). Also known as a [vertex](https://en.wikipedia.org/wiki/Vertex_(graph_theory)) in graph theory.

#### Partition
When one group of peers can't communicate another, such as two servers losing connection between each other, but still serving clients.

#### Peer
A single device on a mesh network. Usually takes both roles of client and server.

#### Pseudo-merge/Union
An intelligent merge between two objects. Unlike `Object.assign`, it uses the [HAM](https://github.com/amark/gun/wiki/Conflict-Resolution-with-Guns) conflict resolution engine to ensure updates are merged commutatively.

#### Pseudo-node/Key Node
A special type of node in gun used for adding secondary indices (via the [`.key()`](https://github.com/amark/gun/wiki/API-(v0.3.x)#key) method). It provides a list of unique IDs to pseudo-merge into an aggregate node.

#### Relation, Reference, Gun reference
A link from one graph node to another. The is denoted by the `#` in the node's object. Looks like `{ '#': 'aOCLhos5ADx3' }`

#### Soul
A synonym for an object [Universally Unique Identifier](https://en.wikipedia.org/wiki/Universally_unique_identifier). Each node in gun has one (named "`#`" in the object metadata).

#### Universe
The sum total of all nodes and graphs across every peer in the application.
