**Metadata** is a second layer of information available in the virtual world, augmenting the perceptive layer.

Depending on visualisation options, it can either be tied //into// the perceptive layer from the person's perspective, or it can register as information that you're simply aware of //like// perceptive cues (rendered much like the vivid memory of a perceptive cue layered across actual perception; called subperceptive), or is altogether invisible until actively queried.

The forms of metadata include:

  * //labels//: textual metadata tied to a specific location
  * //identities//: borders, allegiances, 'true forms'
  * //deep//: background information, event-driven information, or anything else that is not tied to a specific spatial location

Standard Denizen metadata settings are for //labels// to be invisible until queried, //identities// (borders, true forms, allegiances) to be subperceptive, and //deep metadata// to be invisible until queried. //labels// are made visible occasionally.

Denizens that struggle with subperception (it is known to cause dizziness a small sample of the population) may choose to either forgo access to //identity// metadata or make it perceptive, in which case it is usually rendered semi-transparent amongst the landscape.
