====Properties====

**Properties** are the individual pieces of information about an [[assets|asset]].

An asset can have any number of properties.

===Property Types===

There are several different types of property.

**Analogue** properties contain continuous numbers – they are normally used for measurements or numeric figures.

**Status** properties only ever have a value of 1 or 0. Often used for on/off or open/closed indication.

**Enumeration** properties are discrete values (they never have fractions), and they usually represent the status of an asset. They often have more options than simply yes or no (such as Open, Closed or Ajar).

**Text** properties contain character values instead of numbers. There are also several specific formats of text property, such as **IP Address**, **URL** and **Phone Number**.

There are also a variety of other property types such as //symbols// and //models//, that can usually be ignored when performing analytics.

===External Data===

Any property can be [[bound|bound]] to external data. This means that it rather than being a fixed value, the value of the property will change over time and can be either subscribed to or queried.

A single asset may have many properties which can be [[bound|bound]] to different sources. This means that requesting data for a single asset might include information from several different external sources.
