Documentation

This updater consumes SIRI real time information. It is developed by Entur and supports the Nordic Profile for SIRI. It should be possible to develop it further to support a broader set of the SIRI specification.

For more documentation goto the Entur Real-Time Data documentation and the Norwegian SIRI profile .

Configuration

To enable the SIRI updater you need to add it to the updaters section of the router-config.json.

blockReadinessUntilInitialized boolean Whether catching up with the updates should block the readiness check from returning a 'ready' result. Optional false 2.0
feedId string The ID of the feed to apply the updates to. Required 2.0
frequency duration How often the updates should be retrieved. Optional "PT1M" 2.0
fuzzyTripMatching boolean If the fuzzy trip matcher should be used to match trips. Optional false 2.0

Parameter details

url

Since version: 2.0 ∙ Type: string ∙ Cardinality: Required
Path: /updaters/[8]

The URL to send the HTTP requests to.

Use the file protocol to set a directory for reading updates from a directory. The file loader will look for xml files: '*.xml' in the configured directory. The files are renamed by the loader when processed:

    a.xml   ➞   a.xml.inProgress   ➞   a.xml.ok   or   a.xml.failed

headers

Since version: 2.3 ∙ Type: map of string ∙ Cardinality: Optional
Path: /updaters/[8]

HTTP headers to add to the request. Any header key, value can be inserted.

Example configuration
// router-config.json
{
  "updaters" : [
    {
      "type" : "siri-et-updater",
      "url" : "https://example.com/some/path",
      "feedId" : "feed_id",
      "timeout" : "30s",
      "headers" : {
        "Authorization" : "Some-Token"
      }
    }
  ]
}

Siri-SX via HTTPS

Config Parameter Type Summary Req./Opt. Default Value Since
type = "siri-sx-updater" enum The type of the updater. Required 1.5
blockReadinessUntilInitialized boolean Whether catching up with the updates should block the readiness check from returning a 'ready' result. Optional false 2.0
earlyStart duration This value is subtracted from the actual validity defined in the message. Optional "PT0S" 2.0
feedId string The ID of the feed to apply the updates to. Required 2.0
frequency duration How often the updates should be retrieved. Optional "PT1M" 2.0
requestorRef string The requester reference. Optional 2.0
timeout duration The HTTP timeout to download the updates. Optional "PT15S" 2.0

Since version: 2.0 ∙ Type: duration ∙ Cardinality: Optional ∙ Default value: "PT0S"
Path: /updaters/[9]
