Abstract: A system for monitoring a plurality of assets associated with a plurality of spaces may be configured to generate a knowledge graph comprising a plurality of nodes, each node of the plurality of nodes being associated with (i) a respective asset of the plurality of assets or (ii) a respective space of the plurality of spaces; determine a respective initial ranking value for each node of the plurality of nodes; determine a count of outgoing links for each node of the plurality of nodes; perform a node ranking based on the initial ranking values and based on the counts of outgoing links to determine a respective updated ranking value for each node of the plurality of nodes; and determine a respective criticality measure for each node of the plurality of nodes based on the respective updated ranking value.

Abstract: A method of remotely obtaining metadata from a building management system at a building site includes utilizing an intelligent gateway that is disposed at the building site and that is operably coupled with the building management system. A request for the intelligent gateway to obtain metadata from the building management system is received at the intelligent gateway, which applies the metadata request to individual components of the building management system. The intelligent gateway receives the requested metadata from the individual components of the building management system and translates the received metadata into a predetermined format. The intelligent gateway communicates the translated metadata to the remote server.

Abstract: A method includes obtaining a relational model, the relational model comprising a plurality of nodes and a plurality of links, each of the links of the plurality of links connecting one or more nodes of the plurality of nodes, and each link corresponding to a relationship between a first node and a second node, receiving a request to update the relational model, the request comprising information corresponding to an added and/or edited first node, determining a first probability that the first node is in a relationship with a second node and a second probability that the first node is in a relationship with a third node, and updating the relational model to include the relationship between the first node and the second node at the first probability and the relationship between the first node and the third node at the second probability.
