Slovenian TAF in IWXXM | SWIM Registry

Abstract

The service provides the latest TAF reports in IWXXM for Slovenian aerodromes in compliance with ICAO Annex 3. The retrieval of information will be done on a regular basis (subscription) via AMQP 1.0 whereby the message contains the whole IWXXM dataset. The other option to collect the data is via Request/Reply using OGC EDR API, where the IWXXM data is provided in replies, in a ZIP archive.

Performance

Time Behaviour

METAR/SPECI and SIGMET: Under normal operations 90% of messages will be delivered within 10 minutes after the issuing time.
Capacity

Subscriptions are managed with consideration of the capacity of the technical infrastructure. Each connection is rate and connection limited to avoid overload of the system.

Reliability

Availability

Monthly rate superior to 99.5% (max. 3 hours of downtime per month)
Recoverability

There exists a fallback system which ensures recovery after incidents.

Security

Integrity

Integrity is protected by using TLS layer for all the service interface bindings. However the Message Security based on S/MIME 4.0 proposed in SWIM TI Yellow Profile 2.0 is not yet implemented.
Confidentiality

Data delivery is only available for registered users, who need to present their username and password for access to the services using HTTP Authorization header with Basic scheme for HTTP based connections, and using SASL plain for AMQP connections. !!MTLS-STATEMENT-OPTIONAL

Information Retainment

Meteorological information is retained for a period of at least 30 days from the date of issue. This relates to the information itself and not the request time of the user.
Subscription

To subscribe, customers need to contact [email protected] and request access to the service.
Authentication

The service ensures client authentication in accordance with SWIM Technical Infrastructure (TI) Yellow Profile 2.0 requirement SWIM-TIYP-0042 by implementing username and password authentication using HTTP Authorization headers with Basic scheme for HTTPS based interfaces, and using SASL PLAIN for AMQP. !!MTLS-STATEMENT-OPTIONAL. The service ensures server authentication in accordance with SWIM-TIYP-0042.
Authorisation

The service ensures that satisfactory authorisation is put in place according to EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile requirement SWIM-TIYP-0070.
Confidentiality

The service ensures point-to-point confidentiality in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile 2.0 through the use of Transport Layer Security (TLS) 1.3. The communication is encrypted by TLS with a certificate issued by the EACP.
Integrity

The service ensures point-to-point integrity in accordance with EUROCONTROL Specification for SWIM Technical Infrastructure (TI) Yellow Profile through the use of Transport Layer Security (TLS) 1.3.

Filtering Capabilities OGC EDR

The EDR implementation builds on MET3SG community MET SWIM OGC EDR GUIDANCE. Additionally it supports OGC EDR filtering machanisms: cube query using a bbox parameter, area query with a polygon specified in coords parameter, radius query.
Filtering Capabilities AMQP

Simple filtering is achieved using the topic structure of the broker, which determines the type of data recieved. AMQP SQL-like syntax for filters applied to AMQP application properties can be also used by the service consumer to further filter the data received.

The service provider ensures that the data offered within this service is created by ARSO

https://airm.aero/developers/icao-wxxm-3.0.0-to-airm-1.0.0-index

Typical Request/Reply Behaviour

The typical behavior is following:1. Client sends request to the OGC EDR interface2. The service replies with the appropriate HTTP response3. If the request for specific IWXXM data is made, the service returns a zip archive with one or more files containing IWXXM messages.
Typical Data Distribution Behaviour

The service sends the data to subscribers when they are available and match their subscription using the AMQP protocol.
Typical Data Subscription Behaviour

For subscribing to data the consumer needs to contact ARSO Customer Service and needs to request the credentials. After registration the consumer gets the endpoint to all ARSO SWIM services.

For AMQP subscriptions, regular heartbeat messages are sent to weather.aviation.taf topic at approximately 60-second intervals. Arrival of the heartbeat message indicates that the main subsystems of the service are running.
