Building data platform with graph projections

A method comprising:

• retrieving, by a processing circuit, a schema and an ontology for generating a building graph projection, the ontology indicating a permission of a building system, and the ontology indicating allowed relationships between types of entities, the schema to identify a format for information of events;
• retrieving, by the processing circuit based on the permission of the building system, a subset of entities of a plurality of entities representing elements of a building and a plurality of relationships between the subset of entities of the plurality of entities representing relationships between the subset of entities of the plurality of entities;
• constructing, by the processing circuit, the building graph projection according to the ontology, the building graph projection including a plurality of nodes and a plurality of edges constructed to conform to the ontology and constructed to represent the subset of entities of the plurality of entities and the plurality of relationships;
• receiving, by the processing circuit, a plurality of events from one or more pieces of building equipment;
• performing, by the processing circuit, one or more operations on the plurality of events to verify that a format of information associated with the plurality of events conforms to the format identified in the schema based on the building graph projection;
• routing, by the processing circuit, responsive to verification that the format of the information associated with the plurality of events conforms to the format identified in the schema, the plurality of events to at least one topic component based on types of the plurality of events, at least one type of event being telemetry data of the building;
• enriching, by the processing circuit, at least one event of the plurality of events routed to the at least one topic component with contextual data;
• and
• updating, by the processing circuit, the building graph projection to include at least one node to represent the at least one enriched event.

One or more non-transitory memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to:

• retrieve a schema and an ontology for generating a building graph projection, wherein the building graph projection is a digital twin, the ontology indicating a permission of a building system, and the ontology indicating allowed relationships between types of entities, the schema to identify a format for information of events;
• retrieve, based on the permission of the building system, a subset of entities of a plurality of entities representing elements of a building and a plurality of relationships between the subset of entities of the plurality of entities representing relationships between the subset of entities of the plurality of entities;
• construct the building graph projection according to the ontology, the building graph projection including a plurality of nodes and a plurality of edges constructed to conform to the ontology and constructed to represent the subset of entities of the plurality of entities and the plurality of relationships;
• receive a plurality of events from one or more pieces of building equipment;
• perform one or more operations on the plurality of events to verify that a format of information associated with the plurality of events conforms to the format identified in the schema based on the building graph projection;
• route, responsive to verification that the format of the information associated with the plurality of events conforms to the format identified in the schema, the plurality of events to at least one topic component based on types of the plurality of events, at least one type of event being telemetry data of the building;
• enrich at least one event of the plurality of events routed to the at least one topic component with contextual data;
• and
• update, the building graph projection to include at least one node to represent the at least one enriched event.
