Dear All,
Following the decision in Copenhagen, here my proposal:
E18 Physical Stuff
Subclass of: Legal Object
Superclass of: Physical Object
Physical Man-Made Stuff
Physical Feature
Scope Note: Physical stuff is an abstract notion that groups all physical
objects, man-made and natural, as well as physical features
of objects, such as holes. We use the term 'feature' to
refer to anything of a material nature, such as scratches, holes,
rivers, and stains, which it would be strange to refer to
as objects.

the immaterial products. The latter are exclusively
man-made. Physical stuff can only be present at one place at a time, whereas
conceptual objects may be present at multiple places at a
time via multiple physical carriers. Physical stuff ceases to exist by
destruction, whereas conceptual objects ceases to exist by
loss of the last carrier or by forgetting.
Examples: Me, the Cave of Dirou in Peloponnese, the Euphrat
River, Lassie the dog, the logbook of the Endeavor.

E28 Conceptual Object
Subclass of: Man-Made Stuff
Superclass of: Right
Information Object
Type
Scope note: This entity is the attempt to group the non-material products of
our minds, and specifically to allow for reasoning about their identity,
circumstances of creation and historical
implications. Characteristically, these things are created, invented or
thought, and somehow documented or communicated between persons. Conceptual
objects need not have a particular carrier, but may
be found on several different carriers, such as paper, electronic signals,
marks, audio media, paintings, photos, human memory, etc. They cannot be
destroyed as long as they exist on at least one
carrier or in memory. Examples include texts, maps, photos, music, sounds,
fairy tales, signs, patterns, symbols, plans, rights, and rules. A greater
distinction could be made between products having
a clear identity, such as a specific text, or photographs, and the ideas and
concepts shared and traded by groups of people.

our minds and of technical processes such as image taking, and
specifically to allow for reasoning about their identity,
circumstances of creation and historical implications. Characteristically, these

documented or communicated between persons and technical means of

maps, photos, music, sounds, fairy tales, signs, patterns, symbols, plans,
rights, rules, types, taxa and other concepts. A greater

such as a specific text, or photographs, the Information
Objects and the ideas and concepts shared and traded by groups of people.
Conceptual objects are disjoint from physical stuff, the
material things. The latter may be man-made or not. Physical stuff can only
be present at one place at a time, whereas conceptual
objects may be present at multiple places at a time via multiple physical
carriers.
Examples: The contents of "Definition of the
CIDOCobject-oriented Conceptual Reference Model, version 3.3.2, Sept.2002",
the copyright by CIDOC on the latter, the
species fringilla coelebs, the sound track of The Beatles "Yellow
Submarine", Albrecht Dürer's signature,
Unicorn.
