Building automation systems with automatic metadata tagging and viewing

A method for viewing tags associated with entities in a building management system (BMS), the method comprising:

• identifying, by a processing circuit, one or more entities in a system library, wherein the system library comprises a plurality of relationships between a plurality of tags and a plurality of entities;
• obtaining, by the processing circuit, tags associated with the one or more entities based on at least one relationship of the plurality of relationships;
• receiving, by the processing circuit, an input regarding the one or more entities;
• and
• responsive to the input, presenting, via a user interface, a first view of tags corresponding to a first entity of the one or more entities and a second view of tags corresponding to at least one of the first entity or a second entity of the one or more entities.

A building management system (BMS) comprising:

• one or more processors;
• one or more memory devices storing instructions thereon that, when executed by the one or more processors cause the one or more processors to perform operations comprising:
• obtain a system library comprising a plurality of relationships between a plurality of tags and a plurality of entities of the BMS, the plurality of entities of the BMS corresponding to units within the BMS;
• identify one or more entities in the system library;
• retrieve tags associated with the one or more entities;
• and
• represent tags associated with the one or more entities.
