Figure 1
Modified snippet from the metals.yml database file showing sodium properties.

Figure 2
Flowchart for Yamdb showing the essential steps for creating a property and mixture object respectively.






Figure 3
Script-generated report on the thermophysical properties of Li at 800 K using Goma (shortened). Formatting and bibliography require pandoc and LaTeX.

Figure 4
Sodium density according to correlation equations from Yamdb (solid lines) compared to experimental data provided via the NIST Alloy data web application [70, 53, 71]. The original data are from Davies (1972) [9], Khairulin et al. (2013) [34], Ruppersberg and Jost (1989) [56], and Taovo et al. (2009) [62].


Figure 5
Surface tension of CaCl2-NaCl mixtures versus composition for different temperatures adapted from [1]. Correlation expressions (dotted and dashed lines) from Yamdb compared to measured data by Addison, Coldrey [1] (dots and solid lines). Dotted lines result from evaluating the equations by [30] and dashed lines from those of [28]. As expected, the latter are identical to the values by [32].
