Dear Christian-Emil,

I tend to agree with Martin and Martijn.

Although the semantic boundaries between finds and layers could in some cases be ambiguous and in some ways undecidable, there is usually a clear distinction (operated by archaeologists) between the object and the stratigraphic unit in which the object itself is embedded. Talking about physical objects/material things incorporated or embedded within one or more stratum/a is, in my opinion, a better and more clear way to render the scenario you describe.

Therefore, I would go for AP18 + A7 or AP15 + S10 in CRMarchaeo.

Bests,
Achille

Hi christian-emil,
No, a find should not normally be modeled as a stratigraphic unit, because the latter is intended to represent chronologically separable processes such as cutting and filling. In most cases the embedded objects are deposited together with soil as a single bulk deposit, so do not represent an A8 by themselves.
However, examples can be constructed where the deposition of a single object is distinguishable as an event separate from any preceding and subsequent stratigraphic units - think of an urn being deposited in a cremation grave - where the use of A8 would be defensible.
Hope this helps,
Martijn

Sorry for the typos and generally confusing text. Here is a hopefully  a better text:



AP11 has physical relation (is physical relation of)
Domain: A8 Stratigraphic Unit
Range: A8 Stratigraphic Unit

My issue was about finds as objects. That, how do one model physical relations between finds (and also modern objects like the pipe). Can a find be both an object and an A8 Stratigraphic Unit​? Double instanciation? The find being an instance of  A8 Stratigraphic Unit​ as long as it is not moved?

Best

Dear all,

I am working on a mapping from Norwegian excavation databases to CRM/CRMarcheo. The sets use relations like over/under between layers and other A8 Stratigraphic  Units.  A question: Can a find be modeled as an instance of A11 and what about a modern drainage pipe/ditch? 


Best,

Christian-Emil
