Dear all, I will try to succinctly state my ideas on the matter. In terms of the last question:

Which is it? > If the dilemma derives from my previous post, it’s not exactly what I meant to imply. A right IsA Conceptual Object in the CRM sense that it is a product of the mind and fits in the class hierarchy of such real world objects and should be consistent to the modelling thereof. The beginning of existence of a conceptual object relates to its being formulated as a thought and probably somewhere documented. As a well established principle of CRM, instances o conceptual object to not cease to exist until there is no more knowledge of them. Therefore, I would argue that the begin condition of a legal right should be specified in the scope note of E30 to make clearer when it begins and to specifically indicate that this is not when the right comes into force (be extension not when it goes out of force), but rather when the right is formulated. It may be the case that in the scope note which we should enrich, the specific conditions of such a formulation of a right should be further refined in order to detail under what conditions the specific subclass of Conceptual Object that is Right can be said to come into existence. The formulation might speak of how such a begin is not only thinking abstractly of having the right over the Mona Lisa but rather must be asserted as an idea within an known legal framework or according to an established principle or some such under which the Actor in question could conceivably claim/assert this right. I did not intend to say with my remarks that a Right is _merely_ the idea or concept of a right (although I can see how it might have read that way). Rather, I meant to say that because a right has been formulated/claimed (in the restricted sense I mention above) it may have come into existence and yet not be in force (meeting the conditions above of ‘being thought about’ and ‘being formulated by an actor who acts within some known legal framework or principle whereby they can reasonably be assumed to assert such claim). Likewise, once it has gone out of force, I would think that the instance of E30 Right has not ceased to exist but is merely our of force (we did not lose our knowledge about it which I believe is what we would intend if we said that it had ended to exist… there are no more carriers). Quoting from E28 scope: "They (ALL instances of E28 including instances of its subclasses -G.B.) cannot be destroyed. They exist as long as they can be found on at least one carrier or in at least one human memory. Their existence ends when the last carrier and the last memory are lost." So, my intended point was that the begin and end conditions of right are not when it is valid/in force but something else. With regards to Rob's proposal on typing then: > I agree with George that a new property to assert that the [notion of the] > Right applies over a particular timespan would be the easiest solution. Then > has_type can be used to distinguish between actually legal Rights, and ones > that are not legally valid or binding. This would also make the sale of > stolen objects significantly easier to model – it is the creation of a Right, > with a has_type for its illegal status, that applies during the period until > the item is discovered to have been stolen. I don’t think it is necessary. The class, I think, really should pick out just those instances in the world of conceptual object that are specifically real ‘legal privileges concerning material and immaterial thing or their derivatives’. Of course these could be contested. That would be another good use of node (to document some argument for example that it is not valid, as per, I think, Steve’s suggestion). The overall issue should be clarified, in my opinion, by a more robust scope note that specifies the identity, unity, begin and end conditions of existence of instances of E30 Right. With regards to the subsequent modelling question of: >> >> In terms of activities, I don’t think that quite fits, even with the >> problematic-in-RDF P16.1. I could assert that Stephen possesses the >> reproduction rights for the Mona Lisa … that doesn’t imply that Stephen >> carried out any activity. I think that this raises an additional question of the scope note of E7. The scope note of E7 Activity and its label suggest ‘action’ to many users of the CRM: 'This class comprises actions intentionally carried out by instances of E39 Actor that result in changes of state in the cultural, social, or physical systems documented. This notion includes complex, composite and long-lasting actions such as the building of a settlement or a war, as well as simple, short-lived actions such as the opening of a door’ Yet the scope note also indicates, and it is fundamental to many CMR based models, that we are not speaking of some constantly on-going act. The Peloponnesian War lasted 30+ years but there were intervals in which it was not ‘happening' at all. It would still be an instance of E7 to my understanding. What an instance of E7 does necessarily imply to my reading, is some conscious intention towards something (that can be perceived by 3rd parties and therefore documented). So, to my mind, so long as this is the case with the data under discussion (people aren’t taking up rights unbeknownst to themselves), then the E7 used specific object proposal that Steve proposes would function. In fact, in this case, where it seems that the issue under investigation is indeed active participation in arts dealing (if I understood correctly) and who actively used what and in what amount, it seems quite appropriate. The whole thing does raise the issue of whether we make this potential passivity of an instance of E7 action more clear in the scope note. As to Rob’s seconding of my proposal for ‘validity time’ relations on E30: >> I agree with George that a new property to assert that the [notion of the] >> Right applies over a particular timespan would be the easiest solution. Thanks for the seconding. It is true as Steve remarks that we should have use cases or there is no point to model it, but I think there are such use cases and that it would be worth discussing at a SIG. I think the semantics would be different that the 'E7 used object' modelling, since something can be in force and not used (see Greek anti smoking law). This seems to turn toward the questions that were being raised in the last SIG about modelling ‘planned activities’ in relation to E29 Design or Procedures, I believe and could be raised in relation to this? Finally, with regards to the implementation issue and the .1s in RDF, do you or have you tried to use the CRMpc solution? Sorry for the length and hope it was a useful contribution to the conversation.
