The outer Solar System contains a large number of small bodies (known as
trans-Neptunian objects or TNOs) that exhibit diverse types of dynamical
behavior. The classification of bodies in this distant region into dynamical
classes — sub-populations that experience similar orbital evolution — aids in
our understanding of the structure and formation of the Solar System. In this
work, we propose an updated dynamical classification scheme for the outer Solar
System. This approach includes the construction of a new (automated) method for
identifying mean-motion resonances. We apply this algorithm to the current
dataset of TNOs observed by the Dark Energy Survey (DES) and present a working
classification for all of the DES TNOs detected to date. Our classification
scheme yields 1 inner centaur, 19 outer centaurs, 21 scattering disk objects,
47 detached TNOs, 48 securely resonant objects, 7 resonant candidates, and 97
classical belt objects. Among the scattering and detached objects, we detect 8
TNOs with semi-major axes greater than 150 AU.
