Detailed Description

References to external objects.

The external reference is an optional recommendation to refer to objects defined outside of OSI. This could be other OpenX standards, 3rd-party standards or user-defined objects.

Note

ExternalReference is optional and can be left empty.

Member Data Documentation

reference

optional string osi3::ExternalReference::reference = 1

The source of the external references.

Defines the original source of an object as uniquely identifiable reference. In case of using GroundTruth::map_reference or GroundTruth::model_reference, the reference can be left empty. If not otherwise required, an URI is suggested. The syntax should follow RFC 3986.

type

optional string osi3::ExternalReference::type = 2

The type of the external references.

Mandatory value describing the type of the original source.

For OpenX/ASAM standards it is specified as follows:

• net.asam.opendrive
• net.asam.openscenario

For third-party standards and user-defined objects, reverse domain name notation with lower-case type field is recommended to guarantee unique and interoperable identification.

identifier

repeated string osi3::ExternalReference::identifier = 3

The external identifier reference value.

The repeated string is chosen as a common description of the external identifier, because a variety of identifier types could be involved .

For example, referencing a unique lane in OpenDRIVE requires the following identifiers:

• RoadId: String
• S-Value of LaneSection: Double
• LaneId: Int

Note

The detailed description of the identifiers and how they are used for referencing external objects is given in the individual messages where the external identifier is used.
