Clarify RoadEventFeedInfo update_date definition #190

Closed j-d-b closed 3 years ago

j-d-b commented 3 years ago

Following issue #184, this PR updates the description of the RoadEventFeedInfo update_date property to clarify that this timestamp should reflect when the GeoJSON file representing the WZDx feed was generated.

The recency of this property depends on if the producer is following a request/response model where the GeoJSON feed file is generated every time a consumer requests the feed, or if the producer is generating the file on an interval or other trigger and making that file available for consumers.

The WZDx specification does not require either method and there are currently producers doing it both ways.

Let's make sure it gets added to the v4.0 schema before release.
