Interesting Observations

The datasets published at data.gov change on a weekly basis. In order to find out (1) what datasets are available on data.gov, and (2) which datasets were recently updated, we generate RSS feeds daily which use semantic web technologies. The following are some examples:

  • today-raw-ping.rss: list all raw datasets published at data.gov as of today, and update their date by pinging their data access points.
  • diff-today.rss: list recently added, deleted or updated datasets (raw dataset and tool catalog) since last catalog update (see figure).
