linking data to sources and licenses

[markdav-is]

A good example is the little-help-book. If we aggregate that data with another source, there is a creative commons license attached that needs attribution. It would be smart to included source information with the data as it'd delivered.

result {
  sources {
    id: "ploki123",
    license: { 
      id:"CC BY-SA 4.0"
      link:"http://bla..."
  },
  data: [  ... data goes here and rows are links to source_id
  ]
}
