The semantics of temporal hierarchical planners are limited. In hierarchical paradigms, temporal reasoning has largely focused on durative constraints of primitive actions, which may be added directly or appear post-expansion. We propose extending temporal reasoning to composite actions, specifically within decompositional partial order causal linked planning. We outline how a general-purpose hierarchical planner can approach temporal reasoning outlined in a STRIPS-like formalism. We build upon existing temporal and hierarchical semantics, and sketch two novel approaches: time-frame planning and decompositional time-frame planning.
