The Ontological Multidimensional Data Model

Example: Figure 1 shows Hospital and Temporal dimensions. The former’s instance is here on the RHS. K contains predicates Ward(·), Unit(·), Institution(·), etc. Instance DH gives them extensions, e.g. Ward = {W1,W2,W3,W4}. L contains, e.g. WardUnit(·, ·), with extension: WardUnit = {(W1, standard), (W2, standard), (W3, intensive), (W4, terminal)}. In the middle of Figure 1, categorical relations are associated to dimension categories. standard intensive terminal
