9. Big Semantics

Something is a spicy-pizza if-and-only-
if-it is a pizza and has-topping a spicy-
topping.
Something is a vegetarian-pizza if-and-
only-if-it is a pizza and is not a thing
that has-topping a fish-topping and is
not a thing that has-topping a meat-
topping.
Every four-seasons has-topping
nothing-but things that are anchovies-
toppings and-or are caper-toppings
and-or are mozzarella-toppings and-or
are mushroom-toppings and-or are
olive-toppings and-or are peperoni-
sausage-toppings and-or are tomato-
toppings.

12. Linked Data
data published on the web in such a way
that
• it is machine-readable
• its meaning is explicitly defined
• it is linked to other external datasets
• can in turn be linked to from external
datasets
