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 identificatier 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.
