Metadata

Indicates the classification level for a data set, for instance a flight leg. Content is system specific, but the following is recommended:

1. «PUBLIC»
2. «NON-PUBLIC»
3. «RESTRICTED»

The source of the data used to create "something", for instance a flight leg. Content is system specific.

The SourceOrganization that is the source of the data used to create "something", for instance a flight leg. Content is system specific.

The timestamp when something was created, for instance a flight leg. Always UTC.

Comma separated list of the (most important?) data sources that has updated something, for instance a flight leg. Content is system specific.

Type of event. Typically CREATE, RETRIEVE, UPDATE or DELETE, but can be other things. System dependent.

The timestamp when something was last updated, for instance a flight leg. Always UTC.

The time a measurement, typically from a sensor, was taken.

A flight leg has been merged into another flight leg. The resulting flight leg is identified by MergedIntoUniqueFlightLegId.

The message environment used. Used to indicate if this is production, stage, test or development. Airport/system dependent.

Typical values are "PRODUCTION", "STAGE", "TEST", "DEVELOPMENT".

UTC timestamp for when the message/transaction was created.

The message type used in some messaging infrastructure. Often the name of the message.

The message version used in some messaging infrastructure. Any versioning scheme is allowed. System dependent.

Defines if this data set for public display, or not. See also ClassificationLevel. A data set can be classified as "PUBLIC", but for specific reasons this one set of data should not be generally visible anymore.

The precise time (TimestampUTC) the response was generated. Always UTC.

SecurityContext defines the security context of something. Typical use is adding user name to a transaction, and then doing something in the context of that user.

An integer code representing a service specific error. The actual values are described in the service definition.

A textual description of ServiceErrorCode.

SourceData will only exist when the source data is something else than XML or JSON. SourceData will typically be the IATA message or an EFD message from Eurocontrol.

Defines the event that caused the action. Use the most precise event type possible of the ones defined. The defined events are site specific.

The result on the system of processing the "SourceData". For example used if one system processes the data and sends it on to further systems.

UTC timestamp for when the source was updated. If unknown, use current (UTC) time.

A GUID identifying a a transaction in some context. This will often be multiple operations that are related in some way.

Code describing how a transaction was used in a system. For instance, if an AODB receives a transaction there are a number of typical usages:

• A new flight leg can be created
• An existing flight leg can be updated
• The transaction can be ignored due to prioritization
• It can be ignored if it doesn't match an existing flight leg, and isn't the type of transaction that are used to create a flight leg

The DateTimeUTC something is valid from. Will typically be used with reference data to specify a validity period. Something is valid in the period ValidFrom to ValidTo.
