State diagram of the BioScholar application. These are the states and high-level activities available to users. Users may navigate between the 'Start', 'Experimental Design', 'Observations' and 'Interpretations' application views. They can create, copy and delete designs from the list of KEfED models and then edit them from within the KEfED Model Editor. Similarly, they can enter, copy or delete experimental data sets from the list of experiments and then edit data for an individual experiment using the KEfED Data Editor. Finally, they can examine a domain-specific interpretation of experimental data (for neural connectivity based on observations from tract-tracing experiments). These interpretations are based on querying the knowledge base for supporting data elements with links to the publications from which the data is drawn.
