Abstract
A building system of a building including one or more memory devices having instructions thereon, that, when executed by one or more processors, cause the one or more processors to receive a modification to a graph, the graph comprising a plurality of nodes and a plurality of edges between the plurality of nodes, the plurality of nodes representing entities of the building and the plurality of edges representing relationships between the entities of the building. The instructions cause the one or more processors to generate a change feed event, the change feed event recording the modification to the graph and add the change feed event to a change feed comprising a plurality of change feed events representing modifications to the graph at a plurality of different times.
