LightGraphs Skeleton

Aim: To enable in-memory graph operations on millions of nodes

Minimum requirements:

• A light graph object
• labels <-> Node_Id mapping

Skeleton is now level 0

• A light graph object
• labels <-> Node_Id mapping
• Tags

Summary Graph coincide with level 1:

• Label - a must if LightGraphs are used
• Position, Orientation [Also other related such as Velocity etc.]
• Time
• Tags
