5.9.1 About the Property Graph Description Files

A pair of files describe a property graph:

• Vertex file: Describes the vertices of the property graph. This file has an .opv file name extension.

• Edge file: Describes the edges of the property graph. This file has an .ope file name extension.

It is recommended that these two files share the same base name. For example, simple.opv and simple.ope define a property graph.
