Web service composition

Dear list, 

I have been confused when I read papers about web service composition using Golog, HTN (SHOP2) and classical AI planning.
Can someone tell me the difference of these techniques' principles? 
Does classical AI planning construct a plan by assembling the available actions ? (bottom-up method?) 
When using Golog and HTN, should we  write a  generic procedure or workflow  first?  then  the  planners  search the actions for the procedure and implement it? (top-down method?)
 
Thank you for any help.

With best regards.

Figo
