Document Holofood signposting

[stain]

https://www.holofooddata.org/ is a registry of samples and data collected for Hologenomics for sustainable food production. Signposting is used to provide a link from HTML landing page to its corresponding REST API as JSON, with a OpenAPI indicated as its profile.

This is an example of minimal signposting, when no FAIR formats are available yet.

They got their describedby wrong. They use describedBy instead. @stain can you inform them?

[hvdsomp]

@SandyRogers Your Link header implementation uses describedBy instead of describedby as a link relation type. The latter one is registered in the IANA Link Relation Registry and used in FAIR Signposting.
