Where to place the Value Object code that is shared by more than one Aggregate Root?

Question

I have 2 Aggregate Root: One is the Lessor user, and the other is the Lessee user.

class Lessor extends AggregateRoot {}

class Lessee extends AggregateRoot {}

Each of these Aggregate Roots has a email property, it is a Value Object.

class Email extends ValueObject { }

class Lessor extends AggregateRoot {
    private email: Email
}

class Lessee extends AggregateRoot {
    private email: Email
}

I am not sharing an instance of Email, I am sharing the code of Email.

Can I put the Email code in the SharedKernel folder?

• I didn't want to duplicate the Email code by placing it in theDomain folders of each Aggregate Root.
• And don't even put the Email code in one of the Aggregate Roots and import it in the other.
