A set of NodeRED nodes for modeling Digital Twins with semantics.

- dt-asset: represents an observable asset from the real world. It can be composed by other assets.
- dt-event: events can happen internally or externally and can be used to trigger actions or change properties.
- dt-action: an asset can have actuation methods such as
open(),close()... - dt-property: used to define a property of an asset (
temperature,humidity...) - dt-relation: it can be used to (semantically) represent the relation between two nodes.
- dt-graph: it watches the model and creates/updates a knowledge graph everytime the diagram is deployed.
