This class comprises non-material products of our minds, in order to allow for reasoning about their identity, circumstances of creation and historical implications.
Characteristically, instances of this class are created, invented or thought by someone, and then may be documented or communicated between persons. Instances of E28 Conceptual Object may be found on more than one particular carrier, such as papers, electronic signals, marks, audio media, paintings, photos, human memories, etc.
They cannot be destroyed as long as they exist on at least one carrier or in memory.
Their existence ends when the last carrier is lost. A greater distinction can 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.
