The document discusses liability issues related to open data and summarizes a legal case about a shipwreck. In the case, claims were made that notice to mariners did not include information about a sandbank and that navigators could not be expected to have the latest chart. However, the final decision found no negligence, and determined that any professional navigator would have had the latest chart and that the shipwreck was actually due to the condition of the ship. The document also notes that liability for data is not just a legal issue, as governments may pay due to potential bad publicity from lawsuits even if they are not at fault.
