Filling Out the Reference List Classes

The '<Reference_List> class provides a list of internal (i.e., to other PDS4 products) and external citations relevant to the product. The internal references in this class provide the primary method for making associations like:

• Raw data to calibrated data
• Calibrated data to the calibration observation(s) used
• Data to documentation on calibration or observing conditions
• and so on.

The <Reference_List> class is itself optional. When it is included, all internal references (if any) are listed first; external references (if any) are listed second. You may include as many of each type of reference as you like.

For additional explanation, see the PDS4 Standard Reference, or contact your PDS node consultant.

Following are the attributes and subclasses you'll find in <Reference_List>, in label order.

Note that in the PDS4 master schema, all classes have capitalized names; attributes never do.
