Value Ontology, as I have come to understand it, is a description of what the existence we inhabit is; or more accurately, how it is. Since it is a description of a current, observable state of affairs, it gives little importance to its genesis (nothingness, Jehova, some unknowable or as yet unknown something, whatever).
It describes the existence of individual entities, each defined by the act of valuing and self-valuing. An important thing to grasp here (which I think you are having trouble with) is that self-valuing is subordinate to valuing. Entities self-value as a result of valuing. First, there is a need to value, a valuing principle. Out of that need springs self-valuing, as the entity needs to be a coherent whole, or a distinct something, to efficiently value and gain profit from that act of valuing.
This is why existene has shape, why things are things instead of a confused mass of whatever. It is because we value it, and value each self-valuing thing as a thing. We value them as self-valuing because what we observe is the concentrated efforts, or valuing, of a single thing. An atom values the energy around it in a way that translates into our valuing it as an atom, so with the electrons, the molecules and a chainsaw.
A description of shape/s, how the shape/s is/are, and how the shape/s come/s to be.
