Remarks
  - How do we specify the end date?
  - Dates in the future throw warnings "Implausible date"
  - Comments throw warnings "comments must be a full and valid URL"
  - Affected Systems (title) and impact level (description) is provided as string and needs to be parsed or we would need to add more items for each affected system
  - Intervention 'yes' or 'no' should be specified somehow
