Requirement
Title | Semantics of metadata |
Identifier | SWIM-INFO-011 |
Requirement | An information definition that defines metadata fields should base its metadata on the metadata semantics of the AIRM. |
Rationale | Interoperability does not only concern the exchanged information. It also concerns the information about the exchanged information. |
Verification | Consistency |
Examples/Notes | Example: Metadata that may be exchanged includes the lineage of the information and access rights to the information. Note: The AIRM imports the ISO 19115 [RD 4] metadata standard. Note: At the current time, there is a gradual convergence on the use of ISO 19115 for the semantics of metadata. This is particularly true for the Aeronautical Information domain. However, this convergence is not complete. |
Level of Implementation | Recommended |
Guidance
The AIRM imports ISO 19115:2003 - Geographic information — Metadata. This forms the semantic reference used in the AIRM itself. Therefore, in effect, this requirement asks that the metadata fields contained in information definitions conform to the semantics of ISO 19115:2003.
ISO 19115:2003 is used by many ATM business domains. It is mentioned explicitly in ICAO Annex 15 Aeronautical Information Services and in the ICAO Doc 10066 PANS AIM.
Furthermore, other European initiatives such INSPIRE also make use of the same standard. INSPIRE has provided a tool to create metadata in XML format.
Verification Support
Consistency
Check that:
- The definitions of the metadata fields in the information definition are consistent (not contradictory) with the AIRM's metadata standard.
