A node in a [SankeyGraph]
The (matrix) index of the node. This is used as the identifier of this node in the graph. For each linked technosphere flow in the system there can be only one node in the graph.
- Proto-Index: 1
The process-product or process-waste flow described by this node.
- Type: TechFlow
- Proto-Index: 2
The direct contribution of the production (treatment) of the product (waste) flow described by this node to the total result of the system.
- Proto-Index: 3
The total result (upstream and direct) related to the production (treatment) of the product (waste) flow described by this node. Note that this product (waste) flow could be an input (output) of several processes in the system and all these instances are aggregated to a single node here. This is different than in the upstream contribution tree where these instances can be unrolled into multiple nodes (see [UpstreamNode]).
- Proto-Index: 4
The snippet below shows the names of the properties of the corresponding Python class of the olca-schema package. Note that this is not the full class definition but just shows the names of the class and its properties.
