@dpo @arnavk23 I updated the PR to take into account the suggestions. For the specific example illustrated here, I didn't find a DOI. Ideally, the URL field would use the DOI link.
If you guys agree I can then apply to all problems.

@tmigot I think this is excellent! Thank you. If I have

model = aircrfta()

how can I programmatically access its "meta"? Do we have something like meta(model)? Then, we could access its DOI, URL, etc.

All the meta are collected together in a DataFrames accessible like this;

using OptimizationProblems
OptimizationProblems.meta

for a specific problem you could do OptimizationProblems.aircrfta_meta.
However, right now there is no logic to get the meta from the problem, but that should be doable. If you think that's relevant it could be described in a new issue.
