Numerical graphical flow diagram conversion and comparison

A method, comprising:

• receiving, by a computing device, a structured language definition defining a structured language and comprising a plurality of process flow element representations each respectively representing one type of processing node for use in graphical process flow diagrams, with each process flow element representation being characterized by at least:
• (i) a numeric process flow element attribute type identifier, and (ii) a numeric process flow graphical interconnection attribute type identifier;
• receiving, by the computing device, a graphical process flow diagram data set representing a graphical process flow diagram comprising a plurality of processing nodes and a plurality of connections among and between the plurality of processing nodes, with the graphical process flow diagram representing a process flow in a human understandable way;
• and
• translating, by the computing device, the graphical process flow diagram into a structured language data set formed and formatted according to the structured language so that:
• (i) each given processing node of the plurality of processing nodes is respectively represented by an instance process flow element representation having an appropriate numeric process flow element attribute type identifier, and (ii) each given connection of the plurality of connections is respectively represented by appropriate numeric process flow graphical interconnection attribute type identifiers of the instances of the process flow element representations subject to the given connection.
