nhibernate - how to model one to many relationship in domain driven design -

-

i'm using domain driven design , use nhibernate orm

i have entity named certificate , entity named condition , intermediate table saving 1 many relationship between these 2 entity.

a condition can has many certificates

as condition , certificates separate agreagate roots, , based on domain driven rules can not hold agregate in , agregateid can placed inside it. putting below code in condition agregate can not true 

 private list<certificate> _certificatelist;  . . .  public ireadonlycollection<certificate> certificatelist { { return _certificatelist.asreadonly(); } }

and below code seems not true too

 private list<certificateid> _certificateidlist;  . . .  public ireadonlycollection<certificateid> certificateidlist { { return _certificateidlist.asreadonly(); } }

would me model relationship?

thanks

it depends on business rules, if there no rules spanning certificates of same condition reference conditionid within certificate , rely on database query fetch associtations.
