Suggestion: `author` should be an entity, rather than a string

[elichad]

Currently the profile crate has "author": "Fairscape Team". I noticed it because we've just imported the profile into the RO-Crate profile registry and spotted that the author doesn't show up, because so far we assumed that author includes cross-references to other entities rather than having a string value (this is the case for most profiles we see).

We will fix that problem in the registry so that the author displays correctly as-is (eScienceLab/RO-Crate-Profile-Portal#57), but I thought I'd share that you could also improve the profile crate by following the spec-recommended pattern of using a contextual entity for the author, for example:

{
      "@id": "https://w3id.org/fairscape/profile/0.1",
      "@type": ["Dataset", "Profile"],
      ...
      "author": {"@id": "#fairscape-team"},
      ...
}
{
      "@id": "#fairscape-team",
      "@type": "Organization",
      "name": "Fairscape Team",
      "url": <a relevant URL if there is one>
}

(or even better, to list the individual authors themselves using their ORCIDs)
