4.2.1

Metadata shall be collected for aeronautical data processes and exchange points.

ICAO Annex 15 – Sixteenth Edition

4.2.2

Metadata collection shall be applied throughout the aeronautical information data chain, from origination to distribution to the next intended user.
Note. — Detailed specifications concerning metadata are contained in the PANS-AIM (Doc 10066).

ICAO Annex 15 – Sixteenth Edition

1.2.3.2

When a different temporal reference system is used for some applications, the feature catalogue, or the metadata associated with an application schema or a data set, as appropriate, shall include either a description of that system or a citation for a document that describes that temporal reference system.
Note.— ISO Standard 19108*, Annex D, describes some aspects of calendars that may have to be considered in such a description.

ICAO Annex 15 – Sixteenth Edition

4.2

The metadata to be collected shall include, as a minimum:
a) the name of the organizations or entities performing any action of originating, transmitting or manipulating the data;
b) the action performed; and
c) the date and time the action was performed.

Note.— ISO Standard 19115 specifies requirements for geographic information metadata.

PANS-AIM – First Edition

2.1.1.2

A record of data originators should be maintained.
Note.— Metadata requirements in Chapter 4 specify which information is to be recorded for each originator.

2.1.2.1

Collected data shall be verified and validated for compliance with data quality requirements.

Note 1.— Appendix 1 contains aeronautical data attributes and quality requirements (accuracy, resolution and integrity).
Note 2.— Guidance material on the aeronautical data quality requirements (accuracy, resolution, integrity and traceability and protection requirements) may be found in the World Geodetic System — 1984 (WGS-84) Manual (Doc 9674).
Note 3.— Supporting data quality material in respect of data accuracy, publication resolution, and integrity of aeronautical data, together with guidance material in respect to the rounding convention for aeronautical data, is contained in Radio Technical Commission for Aeronautics (RTCA) Document DO-201A/European Organization for Civil Aviation Equipment (EUROCAE) Document ED-77 —Standards for Aeronautical Information (or equivalent).

Note 4.— Guidance material on the management of aeronautical data quality is included in the Manual on the
Quality Management System for Aeronautical Information Management (Doc 9839).
Note 5.— Verification activities may include:
a) comparison processes in which data and information are compared with an independent source;
b) feedback processes in which data and information are compared between their input and output state;
c) processing through multiple independent and different systems, comparing the output of each; this includes performing alternative calculations; and
d) processes in which data and information are compared to the originator’s request.
Note 6.— Validation activities may include:
a) application processes in which data and information are tested;
b) processes in which data and information are compared between two different outputs; and
c) processes in which data and information are compared to an expected range, value or other business rules.

5.3.2

Each data set shall include the following minimum set of metadata:
a) the name of the organizations or entities providing the data set;
b) the date and time when the data set was provided;
c) period of validity of the data set; and
d) any limitations with regard to the use of the data set.

Note.— ISO Standard 19115 specifies requirements for geographic information metadata.

3.6.5

Each quality management system shall include the necessary policies, processes and procedures, including those for the use of metadata, to ensure and verify that aeronautical data is traceable throughout the aeronautical information data chain so as to allow any data anomalies or errors detected in use to be identified by root cause, corrected and communicated to affected users.

ICAO Annex 15 – Sixteenth Edition

5.3.1.2

A description of available digital data sets shall be provided in the form of data product specifications on which basis air navigation users will be able to evaluate the products and determine whether they fulfil the requirements for their intended use (application).

Note.— ISO Standard 19131 outlines the specifications for geographic data products. This may include an overview, specification scope, data product identification, data content and structure, reference system, data quality, data capture, data maintenance, data portrayal, data product delivery, additional information and metadata.
