Title

Mapping of information concepts to the matching AIRM concept

Identifier

SWIM-INFO-016

Requirement

The mapping of an information concept shall contain a trace from the information concept in the information definition to the AIRM concept that has an equivalent or wider meaning.

Rationale

This is a basic trace to establish the semantic correspondence between concepts. Without such a trace the mapping is pointless.

Verification

Correctness

Examples/Notes

Example: An example of trace to an AIRM concept with an equivalent meaning is provided by AIXM. It contains an information concept called “AirportHeliport” that is defined as “A defined area on land or water (including any buildings, installations and equipment) intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft/helicopters.” This traces to the AIRM concept “Aerodrome” that has exactly the same definition.

Note: In cases where the trace is to an AIRM concept that has a wider meaning, SWIM-INFO-018 also applies. An example of a trace to an AIRM concept with a wider meaning can be found in SWIM-INFO-018.

Note: SWIM-INFO-019 requires the use of the AIRM’s unique identifiers in traces.

Level of Implementation

Mandatory

Guidance

This requirement covers the basic trace option for information concepts. The figure below shows how the concept in the information definition (on the left) has a mapping, in this case containing a single trace, to its equivalent AIRM concept. The trace also satisfies the requirement on preservation of meaning.
