ISSUE-463


The concept of derivation seems to have as a central tenet the creation of a new entity. If this is true, I would recommend stating "the construction of a new entity based on a pre-existing entity" as the first phrase in the definition. The current wording of the definition places emphasis on transformation and updates, which should be qualifers of creation rather than the other way around.

It would help to clarify the authors' point of view regarding when entities are created. For example, there are several examples that state physical relocation results in the creation of a new entity. This will not be intuitive to many readers. The melting of ice in example 6 also falls into this category.

It could be argued that all entities derive from other entities, as no idea (or physical object) springs into existance without being influenced by pre-existing entities. Therefore, all entities are created through derivation.
