Hello, I have simulations producing simulation data in a simulation file (A) - raw data in my current project. I want to simulate different simulation runs while varying the parameters. All parameters and meta-information, like some results and interpretations of the simulation data, should be placed in a parameter file, result file, meta-file (B). I have found an enormous amount of data packages [https://github.com/JuliaData](https://github.com/JuliaData).

Currently, I use  
HDF5.jl  
for the simulation data (A), and I am thinking to use  
DataFrame.jl or  
YAML.jl

For (B).

I need to use the meta-files and parameters.  
Is there any overview of which data package to be used when producing this kind of data? Maybe there was an interesting JuliaCon presentation or something.

I appreciate any help you can provide.
