Perhaps we should shift from talking about ontology as a static entity to
talking about the resultant from meshing a purpose-ful ontology with a
contextual ontology. For example, a model of an (intended) problem intervention
system describes the mesh of the problematic situation ontology, the pragmatic
technologies ontology, the sponsors preferences ontology, the expected
operators' knowledge (both sentient and encoded) ontology, and other semiotic
sets. The resulting system model is a situated ontology. (03)
