tag

A piece of semantic information (metadata) associated with a device or point (entity) for the purpose of filtering or grouping entities. Tags identify the purpose of the component or point and its relationship to other entities. For example, you may wish to view only data collected from meters located in maintenance buildings as opposed to those located in office buildings or schools. For this grouping to work, the metering device in each maintenance building includes a tag that associates the meter with all the other maintenance buildings in your system.

JACEs are associated with Supervisors based on tags; searching is done based on tags.

Tags are contained in tag dictionaries. Each tag dictionary is referenced by a unique namespace.
