Issue 585: Examples for A7 Embedding

Starting Date: 
Working Group: 

In the 52nd joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 45th FRBR - CIDOC CRM Harmonization meeting; upon discussing Issue 447, the SIG resolved to start a new issue where to discuss the following (and other) examples for A7 Embedding

  • The calcified layers of fine ash covering body x during the eruption of Mount Vesuvius in AD79. (tentative)

A7 Embedding

San Galgano’s sword embedded at the Hermitage of Monte Siepi, [He retired 
around 1170 to live as a
hermit. as a symbol of peace he embedded his sword in a stone, which can still 
be seen today]

BBC has a documentary about the sword:

Dear All,

For today's discussion, please let me add that the class A7 Embedding has been interpreted wrongly in an overspecialized manner by some members of this Group. An instance of A7 Embedding is nothing else than the substance of the position of every find within a Stratigraphic Volume Unit, regardless whether this material or shape has been documented. It is sufficient as abstract reference of the relative position of the find within the consolidated matter around it. It can be perceived as the ("thick") surface around the find, which necessarily exists before excavation. There exist however particular cases of archaeological investigation which analyze explicitly the embedding matter, for instance for chemical traces, or use the shape of the embedding for reconstructing decayed parts of the find. The class A7 should not be understood to be designed for these exceptional cases only, but for every position determination of a find within a layer.

I hope this helps better understanding the examples.




In the 53rd CIDOC CRM & 46th FRBRoo SIG meeting, the SIG decided to admit the Pompei example to A7 Embedding, on the grounds that it illustrates the geometrical feature surrounding a particular find.
