[Property] isActive [Optionality] Optional [Description] Used to determine if the feature is "active" or not. In the case of MidOceanRidge and ContinentalRift, isActive should be "True" if the ridge is actively spreading, and "False" otherwise. In the case of IslandArc, isActive is "True" if the IslandArc is in the process of being created via subduction, and "False" otherwise. Note that isActive is potentially able to specify a time period for activity/inactivity, but in the GPGIM 1.5 this value is currently limited to a simple true/false. [Used In]
