Schema.org in JSON-LD is the LD (Linked Data) style of JSON format developed by schema.org It contains embedded links to allow applications to follow related data that are hosted on different sites across the Web.

You can use the DOI Content Negotiation service provided by doi.org to represent the content of a given DOI in Schema.org in JSON-LD format.

The Schema.org in JSON-LD format is triggered by the "application/vnd.schemaorg.ld+json" MIME type as shown this HTTP request syntax:

GET https://doi.org/{doi} HTTP/1.1
Accept: application/vnd.schemaorg.ld+json

Here is an example of how to use the DOI Content Negotiation service to get the Schema.org in JSON-LD format of a given DOI:

fyicenter$ curl -H "Accept: application/vnd.schemaorg.ld+json" \
  'https://doi.org/10.1126/science.169.3946.635'

<html><head><title>Handle Redirect</title></head>
<body>
<a href="https://api.crossref.org/v1/works/10.1126%2Fscience.169.3946.635/transform">
https://api.crossref.org/v1/works/10.1126%2Fscience.169.3946.635/transform</a>
</body></html>

Okay, doi.org is not serving this Content Negotiation request directly. It is redirecting you to api.crossref.org to get the response.

You can add the -L option to let "curl" follow the redirected location. api.crossref.org will return you the DOI content in Schema.org in JSON-LD format.

fyicenter$ curl -LH "Accept: application/vnd.schemaorg.ld+json" \
  'https://doi.org/10.1126/science.169.3946.635'

No acceptable resource available.

Too bad. api.crossref.org does not support this content format.
