What's difference between rosrun and register_ros_package?

edit

I followed knowrob tutorials KnowRob basics and Computables.

The way to use rosrun is:

  rosrun rosprolog rosprolog mod_vis
  ?- register_ros_package(ias_semantic_map).

The way to use register_ros_package:

  rosrun rosprolog rosprolog ias_semantic_map

I know the second way can use something like this

  rdf_triple(knowrob:'on-Physical', Top, Bottom).

But what's the major difference idea between them?

Thank you~
