Issue 386: Functional identity of E24 Physical Man Made Thing

Starting Date: 
2018-05-25
Working Group: 
3
Status: 
Open
Background: 

In the 41st joined meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9 and the 34th FRBR - CIDOC CRM Harmonization meeting, the sig resolving the issue 191, reviewed the Martin' proposal and accepted that

"the identity and coming into existence of a Physical Man-made thing must not be bound to the fact of an accidental or intentional Modification of any microscale - this can adequately be described as adding a man-made feature to the thing (and if not, it is indeed a production), but must be tied to the functional identity of the thing, in the same way we describe it for aggregates"

The sig  decided to  open a new issue for keeping track the discussion about modification of the scope note of E24 and P31  in order to be harmonized with Martin's proposal.

Dear All,

I hope for a vivid discussion! Here my humble attempt to redefine what is man-made

E24 Physical Man-Made Thing

Subclass of:         E18 Physical Thing

                           E71 Man-Made Thing

Superclass of:      E22 Man-Made Object

E25 Man-Made Feature

E78 Collection

            Scope Note:        This class comprises all persistent physical items that are purposely created by human activity.

This class comprises man-made objects, such as a swords, and man-made features, such as rock art. No assumptions are made as to the extent of modification required to justify regarding an object as man-made. For example, a “cup and ring” carving on bedrock is regarded as instance of E24 Physical Man-Made Thing.

Instances of this class may act as carriers of instances of E73 Information Object.

 

New Scope Note:         This class comprises all persistent physical items that are purposely created by human activity. This class comprises, besides others, man-made objects, such as a swords, and man-made features, such as rock art. For example, a “cup and ring” carving on bedrock is regarded as instance of E24 Physical Man-Made Thing.

Typically, physical man-made things do not exhibit similarity with the “raw materials” they are produced from. However, enough instances of this class may be the result of modifying pre-existing physical things, preserving larger parts or most of the original matter and structure, which poses the question if they are new or even man-made, in particular in natural history collections. Therefore, the respective interventions of production made on such original material should be obvious and sufficient to regard that the product has a new, distinct identity and intended function and is man-made. Substantial continuity of the previous matter and structure in the new product can be documented by describing the production process also as instance of E81 Transformation.

Whereas interventions of conservation and repair are not regarded to produce a new man-made thing, the results of preparation of natural history specimen that substantially change their natural or original state should be regarded as physical man-made things, including the uncovering of petrified biological features from a solid piece of stone. On the other side, scribbling a museum number on a natural object should not regarded to make it man-made. This notwithstanding, parts, segments, or features of a physical man-made thing may continue to be non-man-made and preserved during the production process, such as the uncovered traces of the Archaeopterix in the Natural History Museum of Vienna, predating the prepared object.

Instances of this class may act as carriers of instances of E73 Information Object.

Current Proposal: 

In the 43rd joint meeting of the CIDOC CRM SIG and ISO/TC46/SC4/WG9; 36th FRBR - CIDOC CRM Harmonization meeting, the sig reviewed MD’s new definition of E24 Physical Man Made Thing and overall accepted it as a working definitions (it has undergone minor modifications too). 
HW: CEO was assigned to rephrase the definition, taking into account discussion that followed.
The new working definition and details of the discussion can be found here
