Check content

Verify the "Miredo" service is not running: # ps ax | grep miredo | grep -v grep If the Miredo process is running, this is a finding. Note: For Appliance OS, "Miredo" is not included by default, this is not a finding.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
