A term from upper ontology work that is handy for discussing ontological layers is "discriminant". By this I intend to mean a general predicate, able to usefully characterize something along one particular semantic dimension. Examples of important discriminants would include: Physical vrs Informational Natural vrs Artificial Real vrs Imaginary Composite vrs Characteristic Individual vrs Collective Atomic vrs Mediating Specific vrs Indefinite Continuant vrs Occurrent Not many discriminants can be found which are simultaneously orthogonal (independent of one another) and general (can be applied to anything) and useful (easy to clearly define and decide). The listing above may in fact be nearly complete (although many would debate its specifics or suggest other candidates). Regardless of the particulars, I suggest that a better semantic model for your "layer 0" would be all and only those discriminants which have all three qualities - independence, generality, and utility - and hence can be employed to help define any class or instance desired. Perhaps the specific discriminants listed above could help in more precisely discussing the less-general (domain-specific) layers of your strawman, or the benefits of distinguishing them.
