  • ITM Example

    • Example 1: A Performance Monitoring Record with One Copy of Each Metric

    Summary contents of the example PMR:

    1. Time collected.
    2. Link to resource that the metrics conceptually describe.
    3. Set of metrics.
    4. Several extension properties (merely to emphasize that extensions are allowed).

    This example shows the same information about the metrics in several different ways.

    1. As a simple table of metric/value pairs.
    2. As a table mapped to the PMR syntax that makes explicit additional information about the metrics, for example the units, that are otherwise only implied by the description.
    3. As an RDF model serialized in Turtle syntax of the entire PMR including all its metrics.
    4. As an RDF model serialized in RDF/XML syntax of the entire PMR including all its metrics.

    Table of Metric/Value Pairs
