# Meta-Bases
**Bases** are used to track notes based on their [[Categories]], [[Types]], [[Entities]] or other metadata. Although they do not adhere to the core [[Meta-Principles|principles]] of the vault, they are a useful addition, as notes can be automatically integrated linked)/embedded into other notes. A typical example in this Vault is a [[Hub]], which uses a embedded Base to list all notes of the type "Hub".
In order to reduce the amount of Bases needed, the actual contents of meta-data fields (e.g `type: "[[Hub]]"` are represented as views, which are referenced as `[[entities.base#Hub]]` .

## Alternatives
- Instead of tracking and embedding notes via Bases, the links could also be added manually. However this is only feasible for a smaller number
