System dynamics is a modeling approach widely used in environmental studies for representing and simulating ecological systems, giving support to prediction and decision making. The knowledge sources for model design are, essentially, data and human expertise. Interestingly, however, the direct influence of ecological meta-data (structural, spatial and temporal properties of data sets) on model design has been little explored. We investigate the use of meta-data to guide and substantiate model design. The approach consists of having properties of a data set and relevant ecological modeling knowledge formally represented in logic, to enable automatic generation of model elements hypotheses that can be endorsed in the data set properties.
