Animation some space

How do we distinguish Local Space/Bone Space,Parent Bone Space,Mesh Space/Component Space,Acter Space,World Space

I have never found a resource explicitly defining the spaces; however, I have spent a lot of time trying to learn all the differences. Below are what I believe the spaces represent.

Local Space: The space relative to the parent bone.

Component Space: The space relative to the component of interest. For example, for a character, the Component Space is usually the space where transforms are all relative to the capsule origin.

World Space: The space relative to the world origin.

Mesh Space: The space relative to the root bone of the mesh. I often just call this Root Space in my own custom plugins.

Actor Space: The space relative to the actor of interest.

I hope that helps a bit.
