Please find some homework about issue 386 below
The scopenote focus on what may be considered to be objects and can be misleading. The unfortunate word thing add to this. (Stuff was better). Further, the detailed specification of what make an instance of E18 Physical Thing to an instance of E24 Physical Human-Made Thing is somewhat contradicted by the scopenote of the subclasses.
E22 Human-Made Object:
“This class comprises physical objects purposely created by human activity. No assumptions are made as to the extent of modification required to justify regarding an object as human-made. For example, an inscribed piece of rock or a preserved butterfly are both regarded as instances of E22 Human-Made Object.”
E25 Human-Made Feature
Scope Note: This class comprises physical features that are purposely created by human activity, such as scratches, artificial caves, artificial water channels, etc. In particular, it includes the information encoding features on mechanical or digital carriers. No assumptions are made as to the extent of modification required to justify regarding a feature as human-made. For example, rock art or even “cup and ring” carvings on bedrock a regarded as types of E25 Human-Made Feature.
We should consider to revise the scopenotes and at least add a reference to the superclass.
Comment to paragraph 1:
Man-made [human-made] in OED:
“Made or caused by human beings (as opposed to occurring or being made naturally); arising from human activity; artificial.”
Human-made in CIDOC-CRM:
“This class comprises all persistent physical items that are purposely created by human activity. This class comprises, besides others, human-made objects, such as a swords, and human-made features, such as rock art. For example, a “cup and ring” carving on bedrock is regarded as instance of E24 Physical Human-Made Thing”
One should be aware that the phrase “purposely created” will exclude many traces of human activity like for example foot paths and old sunken lanes (hollow ways) from being modelled as instances of E18 Human-Made. The OED definition will include such things.
The text indicates only smaller items. May be we could add something larger like a railroad, a harbor, a city, a formal garden, the Suez channel? I added “of any size”.
Comment to paragraph 2:
There are very much natural history examples. A basket made of straw, a papyrus roll and a sheet of vellum are examples of natural material changed into human-made objects. My suggestion is to delete “in particular in natural history collections. Therefore”. This can be moved to the scope note of E22 Human-Made Objects is so desired.
Comment to paragraph 3:
I have suggested an example in fact combining natural history (natural pearl) and jewelry making, see http://samling.nasjonalmuseet.no/no/object/OK-10734 for an actual example. (pearls where not grown artificially until the beginning of the 20th c.
Comment to paragraph 4
I have deleted this short paragraph since the domain of P128 carries (is carried by) is the superclass E18 Physical Thing.
E24 Physical Human-Made Thing
Subclass of: E18 Physical Thing
E71 Human-Made Thing
Superclass of: E22 Human-Made Object
E25 Human-Made Feature
Scope Note: This class comprises all persistent physical items of any size that are purposely created by human activity. This class comprises, besides others, Human-Made objects, such as a swords, and Human-Made features, such as rock art. For example, a “cup and ring” carving on bedrock is regarded as instance of E24 Physical Human-Made Thing.
Instances of Human-Made thing 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 Human-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 human-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 Human-Made thing, the results of preparation of natural history specimen that substantially change their natural or original state should be regarded as physical Human-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 Human-Made. This notwithstanding, parts, sections, segments, or features of a physical Human-Made thing may continue to be non-Human-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.. for example natural pearls used as a part of an eardrop.
Instances of this class may act as carriers of instances of E73 Information Object
