Metagraph Operations Using Bigraph Representation

In this article, we propose an efficient implementation of operations on metagraphs by using an alternative definition of a metagraph. Definitions of the metagraph structures are given. An alternative definition of a metagraph is proposed. Metagraph operations definitions based on alternative definition of a metagraph are discussed. Operations on hierarchical metagraphs are proposed. The nesting binary relation is discussed. Elementary operations on metagraphs are proposed. Complex operations on metagraphs are discussed. An example of using operations over metagraph is given.
