Well, this is sort of where we came in - wanting an event ontology.

It's worth noting that within the CRM itself there is a practice of 
declaring "short-cuts" to finesse over-complex relationships, replacing 
them by a custom property (e.g. property "P130 shows features of" is a 
short-cut for "P15 was influenced by" in the context of an event).

In the specific case you cite, the problem may be not so much to do with 
the need to record events as to do with objects vs. places: there is the 
property "P128 carries (is carried by)" which relates a physical 
man-made thing to an information object.  So inscriptions on objects are 
catered for, but then you have to bring in additional machinery to 
associate the object with the place where it was found, which is what 
you are really interested in.
