Alphabetical List of Attributes

A complete list of all attributes in the Small Bodies Dictionary, in alphabetical order, is available through the PDS4 Data Dictionary page, which is regenerated automatically with each release of the PDS4 Information Model.

To find the Small Bodies attribute list, look down the list of (alphabetically sorted) dictionary prefixes in the left menu for “Attributes in the sb namespace”. Select that item and the list of attributes will be presented on both the left and the right as clickable links.

Clicking on the specific attribute name will produce a grid with the full, formal definition of the attribute, including data type, restrictions on values, and the list of defined permissible values (if any) and their definitions.

Note that attributes might appear as members of different classes, and that their definitions, or more likely their permissible values, might be context-dependent.

Clicking on the class name in the title bar of the attribute grid will take you to the definition of the class containing that attribute.

If the attribute has an associated unit of measure type, that attribute must have an XML attribute called “unit” in its tag when it is used. For example:

<sb:exposure_duration unit="s">10.0</sb:exposure_duration>

You can see valid values to use for the “unit=” XML attribute by clicking on the value of “Unit of Measure Type” in the grid.
