5.1 Introduction

Companies that wish to use DDEX standard messages created in accordance with the AR standard to exchange data relating to apparent anomalies using the web service communication protocol defined in this part of the AR standard must publish a web service endpoint for message delivery.

The web service communication defined in this part of the AR standard comprises the following steps, when sending an anomaly report message:

1. The company detecting the anomaly wishing to send an anomaly report, the sender, shall place any supplementary documents referenced in the anomaly report message onto a file server which is accessible to the intended recipient of the supplementary documents and the anomaly report. The sender and the recipient must agree beforehand how each party is to access the relevant server; and

2. The sender of the anomaly report then calls the recipient’s web service in order to send the anomaly report itself. The anomaly report must reference, if they have been provided, any supplementary documents on the file server identified in Step 1 above.

Similarly, when a company wishes to respond to an anomaly report by sending an anomaly response as defined in the AR standard:

3. It shall place any supplementary documents referenced in the anomaly response onto a file server which is accessible to the intended recipient of the anomaly response, that is, the sender of the original anomaly report. The sender and recipient must agree beforehand how each party is to access the relevant server; and

4. The sender of the anomaly response then calls the recipient’s web service in order to send the anomaly response itself. The anomaly response must reference, if they have been provided, any supplementary documents on the file server identified in Step 3 above.
