The major difference was the that metadata was moved from each individual block into a separate space.

From the foundation of Lima, and until 1862, streets had a different name for each individual block.

For one thing, it seemed to be made of some solid and homogeneous material rather than built up of individual blocks.

One first builds simple models and testbenches for individual blocks.

"We tongue-and-groove them so they lock into position," he said, noting that an individual block can weigh up to 350 pounds.

After that number was determined, individual blocks would be chosen randomly.

Surrounding them are eight more rooted in individual blocks.

The district encompasses 17 individual blocks (13 identified in 1975 and four new in 1996).

What makes the game challenging is that the player cannot move individual blocks directly.

In 2000 came the first attempt to create individual functional blocks of air space above Europe that would be jointly controlled.
