Purpose

This section sets out the minimal metadata requirements to be satisfied by an ICAO data set that is provided as a file. The requirements are based on an analysis of ICAO Annex 15, the PANS-AIM and suggestions from the AIM community.

This section also provides guidance on how to satisfy the requirements. It maps the requirements to the fields found in ISO19115 (2003) and gives examples encoded using ISO 19139 (2007) which is an XML Schema implementation of ISO 19115 (2003).

Note: A newer version of ISO 19115 is now available. This does not substantially change the mapping.

Finally, it provides recommendations on how to complete the mandatory elements in ISO 19115 (2003) which are not required for an ICAO data set. These elements must be provided in order to be valid against ISO 19115 (2003).

Scope

This document covers the minimal metadata requirements on ICAO data sets that are provided as files. It does not:

• consider the metadata to be provided by an information service (as described in the ICAO SWIM Concept); or
• consider the additional metadata required by industry standards regarding obstacle, terrain and aerodrome mapping data; or
• prohibit the addition of additional metadata by AIS.

Figure 1 summarises the ICAO Annex 15 obligations regarding metadata. The AIS has obligations when collecting data from the surveyor/originator and when verifying the data. However, these are not in the scope of this document. Instead, the scope of this document is the obligation on the AIS to provide data sets to the next intended user. Therefore, the requirements set out in this document are those found in “ICAO Data Set” section of the figure. These are supplemented by the need to use the ISO 19100 series as the reference framework, the need for data protection and the need to include geographical information.

Target Audience

The target audience for this document includes, but is not limited to:

• developers of systems in support of the generation of ICAO data sets.
