evaluant role

Feb 10, 2009. changes after discussion at OBI Consortium Workshop Feb 2-6, 2009. accepted as core term.

GROUP: Role Branch

examples of features that could be described in an evaluant: quality.... e.g. "contains 10 pg/ml IL2", or "no glucose detected")

Role call - 17nov-08: JF and MC think an evaluant role is always specified input of a process. Even in the case where we have an assay taking blood as evaluant and outputting blood, the blood is not the specified output at the end of the assay (the concentration of glucose in the blood is)

a role that inheres in a material entity that is realized in an assay in which data is generated about the bearer of the evaluant role

OBI

When a specimen of blood is assayed for glucose concentration, the blood has the evaluant role. When measuring the mass of a mouse, the evaluant is the mouse. When measuring the time of DNA replication, the evaluant is the DNA. When measuring the intensity of light on a surface, the evaluant is the light source.
