This protocol provides a comprehensive set of messages for conveying encoded binary, analog, and alphanumeric data between devices including, but not limited to:

(a) hardware binary input and output values,

(b) hardware analog input and output values,

(c) software binary and analog values,

(d) text string values,

(e) schedule information,

(f) alarm and event information,

(g) files, and

(h) control logic.

This protocol models each building automation and control computer as a collection of data structures called "objects," the properties of which represent various aspects of the hardware, software, and operation of the device. These objects provide a means of identifying and accessing information without requiring knowledge of the details of the device's internal design or configuration.

ISO/IEC 19788-4:2014 specifies, in a rule-based manner, metadata elements and their attributes for the description of learning resources. This includes the rules governing the identification of metadata elements and the specification of metadata attributes.

These metadata elements are used to form the description of a learning resource, i.e. as a metadata learning resource (MLR) record.

This part of ISO/IEC 19788 specifies, using ISO/IEC 19788-1, technical aspects of learning resources, i.e., requirements for use, location, size, etc.
