Assuming there is the theme A built on top of the theme framework B, A has its post meta named like a_{post_meta_created_by_a}, it’s ok.

But for post meta created by B, there are two choices:

  1. Use B’s name, naming its post meta as b_{post_meta_created_by_b}

  2. Use A’s name, so a_{post_meta_created_by_b}

Which is the best?
