  ns0:discussion "–––––––––  Our current representation of geometrical forms is based implicitly on engineering intuitions and, thus, may be changed to reflect the rigor of available spatial ontologies  ––––––––  Shape models provide a set of geometrical abstractions commonly used by physiologists to represent anatomical participants in biological processes.  IMPORTANT: An OPB:Shape model is NOT an OPB:Spatial region. Rather, a shape model is a geometrical abstraction that simply defines a set of mathematical dependencies between Spatial shape amount properties. For example, the surface area a rectangular plate is the product of its major and minor spans. The extent to which such geometrical dependencies are to be represented as OPB:Dependency classes is yet to be determined.  Some Shape models  have more than one topological part (e.g., a wall part and a lumenal part). Each part can be filled by a portion of material (e.g., cardiac muscle, blood, air) whose Dynamical properties may be equated with Shape model properties; for example the Lumenal volume of shape lumen could be equated with the Fluid volume of the portion of fluid occupying the shape lumen.  The set of Shape model classes is quite sparse and are not intended to be exhaustive. For example where a cardiac ventricle and its contained blood have a very complex geometry which has been modeled as a thick-walled sphere of cardiac muscle enclosing a portion of blood. To pursue more complex geometries (e.g., thick-walled ellipsoid, thick-walled hemiellipsoid) exposes a representative slippery slope that is, rightfully, the  domain of spatial and geometrical ontologies devoted to such tasks. Our current goal is to represent commonly used, simple geometrical abstractions -- the 80% solution for available modeling use-cases." ;
