Note: is_realization of some analyte role isn't always true, for example when there is none of the analyte in the evaluant. For the moment we are writing it this way, but when the information ontology is further worked out this will be replaced with a condition discussing the measurement. example of usage: In lab test for blood glucose, the test is the assay, the blood bears evaluant_role and glucose bears the analyte role. The evaluant is considered an input to the assay and the information entity that records the measurement of glucose concentration the output ready for release
