Is there are way to access the metamodel, instantiate a node or edge of a specific type and add it to the graph in a script?
Please note: The booggie-project does not exist anymore but led to the development of Soley Studio which covers the same functionality.
Yes, you can get the node/edges types from the metamodel using
graph.Model.NodeModel.GetType("MyNodeType")
graph.Model.EdgeModel.GetType("MyEdgeType")
Using the method graph.AddNode
you can add it to the graph and the added node is returned to which attribute assignments can be made.
All together, it looks like this:
newNode = graph.AddNode(graph.Model.NodeModel.GetType("MyNodeType"))
newNode.myAttribute = 42
