Virtual nodes and edges refer to entities created by the transformation of existing nodes and edges. For instance, grouping a set of nodes based on their properties creates a unique node that represents the aggregation of those nodes. We’ll refer to the created node as a virtual node.
This new version sets the basis for additional graph transformation possibilities. In Ogma 2.1, we improved the nodes and edges grouping transformation. You can now combine them. We are currently working on additional transformations such as neighbors merging or node collapsing.
