Filtering Capabilities OGC EDR
The EDR implementation builds on MET3SG community MET SWIM OGC EDR GUIDANCE.
-
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 also be 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 ROMATSA, a REGULATED_METEOROLOGICAL_SERVICE_PROVIDER.

Typical Request/Reply Behaviour
The typical behavior is following:
- The client sends a request to the OGC EDR interface
- The service replies with the appropriate HTTP response
- 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 the Service Provider and needs to request the credentials. After registration, the consumer is provided the endpoints for both EDR and AMQP interfaces.
-
For AMQP subscriptions, regular heartbeat messages are sent to weather.aviation.sigmet topic at approximately 60-second intervals. Arrival of the heartbeat message indicates that the main subsystems of the service are running.
ROMATSA IT components are monitored 24/7
