On implementing the new Collection entity, recognized that the ownership and custody links refer only to Physical Object.
Now, once we regard Collections as non-objects in general, including sites and features, by sure they should by owned and kept. For Features in general I ask myself if "custody" makes sense. Probably yes, even though the keeper has to move to the site, rather than the object to the keepers facilities. An excavation site may have a keeper, as well as some rock paintings. So I propose to raise the domain of the ownerhip and custody links to Physical Stuff.
