This section describes the features which make up OS MasterMap Highways Network - Asset Management. The attributes associated with these feature types are listed below along with a brief description of their data properties.
The name of the attribute and what it is describing.
The nature of the attribute, for example a numeric value or a code list value.
The length of the attribute provided (optional).
Describes how many times this element is expected to be populated in the data. An attribute may be optional or mandatory within the product. These are denoted by:
‘1’ – there must be a value.
‘0..1’ – population is optional but a maximum of one attribute will be returned These values may be used in combination.
Asset management information provides additional information describing the network to support its long- term operation and maintenance which has been sourced from the road or highways authorities. This includes Maintenance, Reinstatement and Special Designation.
Maintenance provides information about whether the road is maintained at public expense by a national or local highway authority, a road authority, or is maintained by another responsible organisation (i.e. not maintained at public expense). If a path is prospectively maintainable at public expense, then this is not currently maintained by a road or highway authority, but the responsible organisation has started the process for a highway or road authority to become responsible for the maintenance of the street at public expense.
Maintenance responsibility is not an indication of ownership.
A Maintenance feature will reference back to the Roads product through Network Reference and will reference a Street Feature. Features which are a partial reference will provide a Network Reference Location. For more information on Network References, see Routing and Asset Management feature information.
Indication of whether the highway is maintained by a Highways Authority, Local Highways Authority, Road Authority or privately.

When maintenanceResponsibility = Not Maintained at Public Expense, the maintenanceAuthority will be null.
Attribute name: maintenanceAuthority

Multiplicity: [0..1]
Flag to indicate that the maintenance feature partially references a Street.
Attribute name: partialReference
Type: Boolean

Multiplicity: [1]
The authority which the highway resides in. Note: When the maintenanceAuthoirty is Highways England, then highwayAuthority will be set to Highways England. When maintenanceResponsibility = Not Maintained at Public Expense, then this is the authority the works operator must contact when applying to carry out works on this street.

Reinstatement defines the standard to which the path must be restored following opening due to works in the highway, as defined in the New Roads and Street Works Act Specification for the Reinstatement of Openings in Highways in England and Wales and the New Roads and Street Works Act 1991 Specification for the Reinstatement of Openings in Roads in Scotland.
A Reinstatement feature will reference back to the Road Network through a Network Reference and will reference a Street Feature. Features which are a partial reference will provide a Network Reference Location. For more information on Network References see Routing and Asset Management feature information.

Special Designations are statutory and advisory designations that can be applied to protect a highway when street or road works are to be undertaken. A Special Designation feature will reference back to the Roads product through Network Reference and will reference a Street Feature. Features which are a partial reference will provide a Network Reference Location. For more information on Network References see Routing and Asset Management feature information.
