Representation of curator activity: inference from experimental evidence. The pattern to represent inference from evaluation of the reported experimental evidence, in contrast to inference based on author statement (Figure 7), is illustrated here by linking curator assertion A30 to a new composite assertion involving curator assertions A31 and A32. These are, in turn, linked to the composite assertions A9-A12 and A15-A20, respectively. These composite assertions reflect data and procedures reported in Tate 1972. Taken together this graph therefore represents a curator conclusion (A30) based on the affirmative outcome (A31, A32) of the evaluation of the data and procedures reported in Tate 1972. Note that A2, the principal conclusion of Tate et al. is unrelated to the new composite assertion. Curator assertions and their links to the Tate et al. argumentation are shown in bold. Color code as in Figure 1.
