Nexus core concepts

Prefixes

Almost all objects in Nexus (users, tasks, topics and locks) are organized in a tree structure. The string resulting of joining (with dots) every node of the tree is called a prefix:

Giving the following tree of Nexus users:

admins
├─ service1
│  └─ user1
└─ ...

The prefix to user1 would be admins.service1.user1.

Prefixes are one of the most important concepts of Nexus as many of its features rely on their hierarchical structure.

For example, when a permissions is given to a user on a prefix, it applies to all the nodes under that prefix.
