Easiest File Format for Animation?

I wanto write a loader for a model that has animations as part of it. Whats the easiest format for this? I would probably be making the animations and model in maya. By the way, can somebody explain what the f lines are in obj files? Thanks

Just incase anybody was wondering I figured out those f lines

I’m not 100% sure, but Maya should support MD2 models. Don’t know any more simple format for animated models.
