Explain how to comply with the FAIR chemical structures specification

[egonw]

Internal reference

#657 and #639

Description

A the BioHackathon Europe 2022 this was discussed with @AlasdairGray and Evan Bolton. Since then, the properties have been made optional, but the explanation in the description never got in.

Motivation and context

• The explanation should explain how to use Bioschemas to provide data needed to be a "FAIR chemical structure".

Have these been tested?

No.

What should reviewers focus on?

That the JSON is correct. I tried using the DDE, which sort of worked, but the JSON was so much different, even though I did start with the DDE version of 0.7-DRAFT that I went for the JSON in this repo.

Types of changes

• Bug fix (non-breaking change which fixes an issue)
• New content (non-breaking change which adds new content)
• Modified content (non-breaking change which modifies existing content)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Future TO-DOs

• e.g. Once reviewed, check webpage update...

The JSON file above displays fine in the DDE, but getting it to propagate to the website is another story (see #643)
