This picks up on Bernard's point regarding Sets in RM. I appreciate that RM does not subscribe to any mathematical set model but i wonder about when do individuals become sets? I'm not sure I found it but if I have two assertions in different maps where: graham worksfor empolis gmbh graham worksfor empolis uk and I merge them what happens? is it now true that graham worksfor [empolis gmbh, empolis uk] through merging, or are the two assertions seperate?

Exact. But if the role player x is not a set, how do you make distinct the subject x and the set {x}? The second one is also a subject, which is exactly the set of subjects that play the role ... So you have a problem here, and the only consistent way I see to solve it is to say: "a role player is always a set of subjects". |
