1. A building automation system (BAS) comprising:

  • a plurality of end devices each associated with at least one of a space, a system, or a subsystem for at least a portion of a building or a campus;

    at least one communication network communicatively coupling at least a portion of the plurality of end devices and supporting a plurality of communication protocols;

    a protocol-independent server engine communicatively coupled to the at least one communication network, the server engine including;

    programming means for selectively implementing a dynamic extensibility capability for the BAS that establishes communications with and control of the plurality of end devices over at least one of the plurality of communication protocols; and

    programming means for selectively implementing an automatic configuration capability for the BAS that supports addition of end devices to the plurality of end devices by determining at least one characteristic of each end device, the at least one characteristic being selected from the set consisting of a self-describing status and a non-self-describing status, including;

    for an end device having a self-describing status, programming means for accepting and storing data and metadata descriptors communicated from the end device; and

    for an end device having a non-self-describing status, programming means for searching a database of data and metadata descriptors for end devices maintained by the server engine for data and metadata descriptors based on the non-self-describing status of the end device and for automatically requesting supplemental manually programmed data and metadata descriptors for the end device if the non-self-describing status of the device is not sufficient to retrieve data and metadata descriptors for the end device from the database.
