As I understand it, each attribute on a content class is typed with a datatype e.g. String, xmlText, etc.

Is there a datatype for "Link to another content object"?
Is there a data type for "Set of links to other content objects"?

Is is possible for me to figure out the answers to these myself without looking at the source code?

I would like to have something like
class B
some attributes of B
end

class A
name: String
good_bs: Set of Bs
bad_bs: Set of Bs
end

I believe "Related Objects" will allow me to group some related Bs into each A_object. However, I do not believe it will allow me to distinguish the good_bs from the bad_bs for a given A_object.

Thanks.

There is a object relation, but this works for one relation at a time.

For this and other attribute types (like URL) it would be logical to have the option to specify multiple items (like the general related objects do).

Thanks Paul.

Where can I learn more about "object relation"? I tried to google-search the site ez.no and did not have much luck.

Do I understand you correctly that (a) I can currently do:
class A
the_best_B: B
end

but cannot do:
class A
all_good_bs: Set of Bs
end

class A
name: String
good_bs: Set of Bs
bad_bs: Set of Bs
end

To achive the above couldn't you make another attribute in Class B named "rating" and give enumerated values like "Good", "Bad" and "Best".

Now you are anyways getting list of B's . But with this attribute you can also distiguish between those B's i.e. they are good or bad or best.

I dont know why this idea didn't struct you all ? Or am i completly wrong?
