h3. Object Entering and Leaving

The transient information (object entering a collection) is recorded as Activities.
We have one activity (the blank node \[\] below) The transient information (object entering a collection) is recorded as Event that is multi-typed with all relevant activity types mentioned above:
{code}
# date the object entered the collection
[] a crm:E79.Part_Addition, crm:E10.Transfer_of_Custody, crm:E8.Acquisition;
crm:P111F.added obj:; crm:P30F.transferred_custody_of obj:, crm:P24F.transferred_title_of obj:;

It can be argued if the last note belongs to the activity, or object, or the association "object - collection"...

Similarly for object leaving a collection.
{code}
# date the object left the collection.

crm:P113F.removed obj:; crm:P30F.transferred_custody_of obj:;

"Leaving" is not in the XML, it's made up to see how it would be modeled), and Leaving is not consistent with "current" P46, P50, P54 in the next section

h3. Former and Current Situation

We also have to record the former and current situation of the object (custody\->keeper, Acquisition(title)\->owner, collection.location\->location):
{code}
# for the current (i.e. last) collection
obj: crm:P46B.forms_part_of rkd:collection/Mauritshuis;
crm:P50F.has_current_keeper rkd:collection/Mauritshuis;
crm:P52F.has_current_owner rkd:collection/Rijksmuseum;
crm:P54F.has_current_permanent_location rkd:place/TheHague.
# for older collections:
obj: crm:P49F.has_former_or_current_keeper rkd:collection/SnijersPJ;
crm:P51F.has_former_or_current_owner rkd:collection/SnijersPJ;
crm:P53F.has_former_or_current_location rkd:place/Antwerpen.
# Former (historic) facts: all but last collection
<obj/2926> crm:P49_has_former_or_current_keeper rkd-collection:WillemV.
<obj/2926> crm:P51_has_former_or_current_owner rkd-collection:WillemV.
<obj/2926> crm:P53_has_former_or_current_location rkd-place:TheHague.
# Current facts: for last collection
<obj/2926> crm:P46i_forms_part_of rkd-collection:Mauritshuis.
<obj/2926> crm:P50_has_current_keeper rkd-collection:Mauritshuis.
<obj/2926> crm:P52_has_current_owner rkd-collection:Rijksmuseum.
