Locator Sets vs. Relations

• Commonalties

  • flat sets
  • identity defined by identity of components
  • concatenation to derive new locators/tuples

• Differences

  • arity
    • locators: variable length
    • tuples: fixed
  • access to components:
    • locators: by navigation
    • tuples: by position/attribute
  • data:
    • locator components: document nodestuples components: values
