descriptive metadata specification

Let L = Dk be a set of literals defined as the union of domains Dk of simple datatypes (e.g., strings, numbers, dates, etc.). Let also R and P represent sets of labels for resources and properties respectively. A descriptive metadata specification is a structure (G, R L P, F), where: (1) F : (V E) → (R L P) can assign general labels R P and literals from L to nodes of the graph structure; (2) for each directed edge e = (vi , vj) of G, F(vi) R L, F(vj ) R L and F(e) P; (3) F(vk) L if and only if node vk has outdegree 0.
