The application domain is a catalogue of Japanese animation, the =
creators and writers/directors of such, as well as characters and the =
IPs (Intellectual Properties) they belong to. An example of a domain =
entity here would be Series (a kind of Adaptation), with a value for =
amount of episodes, along with operations for adding characters to the =
series, adding alternative (different language) names for the series, =
and so on.

I'm using a text editor to define my domain classes, and then feed that =
into a code generator to output domain classes which I can ideally slot =
right into an Isis project. An example class in EMF would be the =
following:

class Adaptation {
	val Title[+] titles;
	ref IP[1] adaptationOf;
	op Title addToTitles(Title title);
	op String title();
}

the keyword val indicates that the variable is to be contained within =
the object, while ref indicates a pointer (Title and IP are other domain =
classes). op defines a method and its name, return type, and parameters. =
The [ ] are for multiplicity.

The current objective I would say is to examine the possibility and =
practicality of integrating a model-driven software development approach =
with the Isis framework in order to enable domain-driven design using =
model-generated code that can then use the naked objects framework and =
its benefits with Isis.

Hope that clears some things up.

Thank you again,
