Issue 475: Transfer of Custody
Posted by Robert Sanderson on 19/2/2020
At a recent Linked Art meeting we were discussing Exhibitions and the relationship to displays and art gallery presentations. In reading the fine print, so to speak, of the Transfer of Custody scope note, we noticed and would appreciate clarification about the following:
> This class comprises transfers of physical custody of objects between instances of E39 Actor.
> The distinction between the legal responsibility for custody and the actual physical possession of the object should be expressed using the property P2 has type (is type of).
So, the question is whether a transfer of legal custody can be modeled with E10, if either we do not know that physical custody was involved or if we know that it was not.
Rob auctions his copy of LaRoche’s “Three Red Wolves” on Ebay. Does Ebay have custody of it in order to facilitate the sale?
Rob sells his house. Clearly the house is not in the physical possession of anyone other than me, but while the sale is pending, I have ascribed some degree of legal custody to others?
We do not know whether the original object is physically present at an auction house or not. If it’s a big statue, maybe the auction house only has a photograph of it. Even if it’s a painting, the original may not be there (it might have been viewable in a controlled environment previously for example). In these cases, there is enough legal custody to be able to negotiate the sale, but it is unknown whether there was explicitly physical custody. Ditto for consignment of objects.
If E10 is only for physical custody, then how would we describe legal-but-not-physical custody? And if we can just use a P2 on the E10, then it would be great to change the first line of the scope note to address that.
In the 46th joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 39th FRBR - CIDOC CRM Harmonization meeting; the crm-sig discussed that since the scope note for E10 Transfer of Custody is not all too well understood, it probably it needs revising. The sig assigned RS to propose new scope note that resolves ambiguities.

In accordance with protocols, here is the proposed HW from issue 475.

Homework from yesterday for issue 475 -- fix the first sentence of the second paragraph of the scope notes for Transfer of Custody to reflect the new understanding as described in the new first sentence of the first paragraph.
The distinction between the legal responsibility for custody and the actual physical possession of the object should be expressed using the property P2 has type (is type of).
In the event that only a single kind of transfer of custody, either the legal responsibility for the custody or the actual physical possession of the object but not both, is represented by the E10 Transfer of Custody, this difference should be expressed using the property P2 has type (is type of).

As noted in the working document for 475, the changes are generally accepted, and thus we should also add an example.
* The legal responsibility for physical custody (but not actual physical custody) of a large statue is transferred from the statue's private owner to the Sotheby's auction house to facilitate its sale.

This is a correct example, but it is categorical. By rule, such examples may go into the scope note, if particularly useful. Please find a real, particular example.
In the 47th joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 40th FRBR - CIDOC CRM Harmonization meeting; the SIG members support the proposal, and discussed how to best formulate the scope note. There was extensive editing on the first sentence of the scope note but for lack of time, RS volunteered to fix the 1st sentence of the 2nd paragraph by session 2.3 as HW.
