Linked data

The metadata collected or reasoned about in an edge node during some temporal window are included in a report from the given node. An example of a report can be visualised as follows:

The structure of this report is as follows:

  • The edge node
  • The report
    • Is created by the edge node
    • Is described by its name “Report from AIT node” and its temporal window
      • <contact:fullName>Report from AIT node</contact:fullName>
      • <dc:date>2012-03-16</dc:date>
      • <smart:issueTime>12:37:30</smart:issueTime>
    • Is the creator of three sub-reports
      • Crowd analysis results
      • Gas analysis results
      • Environmental data
    • Visual description
  • Crowd analysis sub-report
  • Gas analysis sub-report
  • Environmental data sub-report
    • Is created by the report
    • Is described by its name
      • <contact:fullName>Environmental conditions</contact:fullName>
    • Contains lots of environmental data
