DataFeed

DataFeed is a Dataset subtype for feeds that publish a stream of data-carrying items over time: live-action government data, sensor telemetry feeds, marketplace inventory feeds, news-alert feeds. It adds 1 direct property:

  • dataFeedElement (DataFeedItem, Thing, or Text): the elements of the feed. A feed typically has many.

For batch-downloadable datasets use Dataset directly; for items-updated-over-time use DataFeed.

Common DataFeed mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    Dataset for continuously-updated feeds

    Wrong
    Dataset for a live sensor stream
    Right
    DataFeed when items are updated over time; Dataset for batch-downloadable snapshots

    Feed consumers poll dataFeedElement; Dataset consumers fetch distribution URLs. Using the wrong type routes consumers incorrectly.
