OBJ asset files can open successfully while still losing important data. The metadata inspection check should look beyond file validity to units, hierarchy, animation, metadata, and external dependencies.
For OBJ asset, keep the metadata inspection pass focused on units and axes, authorship data, and custom properties. Make one controlled change at a time and retain enough evidence for another person to repeat the decision.
Inspect units, authorship, timestamps, hierarchy, custom properties, coordinate references, and embedded application data. Apply this metadata inspection guidance to the actual OBJ asset delivery path.
