about user defined function in user defined rule

Hi,

 

I am wondering if I can use a user defined function in a user defined rule in oracle sem.. I've seen examples of user defined function used in sparql query filter clause in that dev. guide. However, I don't know if I can define a function in oracle sem. database and use it in the rule body or head. For example, I want to define a duration function that calculate the date difference between two dates.  Then, I want to define a rule like this: event1 :has_start_date d1 and event1: has_end_date d2 and duration (24, d1,d2) then event1:date_satisfiable "yes". Does oracle support this kind of rule? Thank you very much.
