property

A specific attribute of an individual. Classes can be defined to have properties so that individuals of the class can have values for those properties. OWL properties represent relationships between two individuals. There are two main types of properties:

• Object properties (sometimes also called Resource properties)
  • Object properties link an individual to an individual.
• Datatype properties (sometimes also called Literal properties)
  • Datatype properties link an individual to an XML Schema Datatype value or an rdf literal.

OWL also has a third type of property:

• Annotation properties
  • Annotation properties can be used to add information (metadata — data about data) to classes, individuals and object/datatype properties.

In OWL, properties can have sub properties which specialize their super properties. For example, the sub property hasMother might specialise the more general property of hasParent.

In OWL, a property can be defined as:

• the inverse of another corresponding property,
• functional,
• inverse functional,
• transitive,
• symmetric.

OWL-DL does not allow datatype properties to be transitive, symmetric or have inverse properties.

A property can have a domain and a range.

A binary relation that states relationships between classes/individuals or from an class/individual to data value. Property can be further distinguished as ObjectTypeProperty or DataTypeProperty.

For this survey, property means real estate; that is, land and anything permanently affixed to the land, such as buildings and those things attached to the buildings, such as light fixtures, plumbing and heating fixtures, or other such items which would be personal property if not attached. A property may consist of a single-family house (attached or detached), a multifamily house, a condominium unit, a mobile home, an apartment building, or a group of apartment buildings.
For this survey, if a property is mortgaged, the property is all land and buildings covered by a single first mortgage. If the property is not mortgaged, the land and buildings identified by the address in Item A on the survey questionnaire address label is the property.

An object of ownership whereby the owner can exclude others from its enjoyment.

An element of metadata for a document profile. Each document profile has multiple properties. Properties can be system-defined, such as file size or creation date, or can be user-defined, such as title or keywords. See also: metadata

Characteristics of an object that users can set, such as the color of a window.
