Use Cases for Content Standard Evaluation

The use cases to be addressed by the Content Standard evaluation work.

These are the four use cases to be addressed by the instances of sensor metadata descriptions.

  1. Search via Catalog Metadata from a 'raw' data stream will be fed directly into a data catalog and clearinghouse (e.g., the Geospatial One Stop). The data is reported directly from a sensor on a fixed platform. Describe any sensor-related information needed to allow potential users to search for the data by variable name or sensor type?

    The metadata description for the sensor should assume the clearinghouse is fully capable of representing whatever information is deemed necessary for the search.

  2. Find Data, Use Data (Automatically) Data from a CTD sensor is made available via the Internet by displaying an icon on a map. Describe the sensor-related information needed to allow a visitor to find and use the original data used to create the icon. Include as a goal automatically accessing the data based on the metadata associated with the icon.

  3. Deployment Tracking, Maintenance (Usage History), Data Processing, Sensor Control A sensor is deployed as part of a deep ocean observatory. The sensor may be mobile, deployed at multiple depths during a mission. Physical access to the sensor is very limited.

    Describe the sensor and its context to meet the following goals:

    • many people remotely access the sensor, for example to configure it
    • data from the sensor is automatically delivered at frequent intervals, and must be received, presented, and processed by a host system on shore
    • use the sensor deployment history to maintain it in an operational state, including troubleshooting and repair

  4. Deep Historical Analysis A sensor's data set must be analyzed a year after it has been collected. The analysis must address the accuracy of the sensor's readings, including the quality control of the data and the quality assurance procedures applied to the sensor. Describe metadata to be captured to allow these analyses to be performed.

  5. These use cases may be refined by planners and participants leading up to start of the workshop.
