Add a JSON schema

[odow]

We should add a JSON schema that can be used to validate lattice and problem files.

As examples, see:

• https://github.com/jump-dev/MathOptFormat/blob/master/schemas/mof.1.4.schema.json
• https://github.com/odow/StochOptFormat/blob/master/versions/sof-0.3.schema.json

JSON-schema is defined by:

• https://json-schema.org

There is a Python library for validating:

• https://python-jsonschema.readthedocs.io/en/stable/

I think this is really interesting and helpful. I will definitely add this. Thanks for the suggestion!

Hi Oscar , How are you? I am coming to the last stages of the benchmarking and I have two new additional real-world problems that the MSPFormat reader cannot read successfully.

Problem_16.tar.gz Problem_17.tar.gz

I am also slowly addressing each issues on the MSPLib GitHub repo (specifically this JSON Schema and the MetaData). Thanks again for the recommendations.

Do you have a log of the errors?

(p.s. Are you coming to Paris with Nils?)

For Problem #16:

For Problem #17:

Vincent Leclere invited me to give a talk but I could not as I have my defence on the 13th October. It would be nice though. Nils is going only for his talk, if I am not mistaken.

If you have time, Luxembourg is a 2-hour train ride and I I can show you around!

Hmm. So these errors are because storage_5 appears as a state variable, but it does not appear in every stage. We can work-around this in the SDDP reader, but more generally, we should ask: does the vector of state variables need to be constant across the nodes in a graph?

The files contain Dict{String, Any}("MIN" => 9.549789656601526) and Dict{String, Any}("MAX" => 0.0). What are these nodes?

[bonnkleiford]

Hmmm. I am also not sure. Let me check this up with Nils.
