        The purpose of Caliper is to define a standard to measure and share
        learning data. Most of the learning applications work in silos and
        separate data has been captured by each learning application. The problem
        that these separate data sources create is that each organization need to
        reinvent the analytics wheel and more often than not these separate data
        sources cannot be merged and therefore, none of the parties have a
        complete picture. Therefore, a standard way of capturing and sharing
        learning data enables more efficient development of learning analytics
        features in learning environments and Caliper does that. Caliper defines
        a common language for labeling learning data and provides a standard way
        of measuring learning activities.

            Metric Profile: This is a information model for Caliper and is
            organized by learning activity type. For example: Session Metric
            Profile and a Reading Metric Profile. A Metric Profile includes
            Entity, Actions and Events.

        <h3>End Point</h3>
        A Caliper Endpoint receives Caliper data sent through a HTTP POST request
        by a Caliper Sensor. The connection must be secured through the Transport
        Layer Security (TLS). The Endpoint must reply with a
        response message after the receipt of a sensor request message. The
        response will include a three-digit status code indicating whether or not
        the Endpoint was able to understand and satisfy the request.
