ISBN Seed Metadata¶

ISBN Seed Metadata for interoperable Meta-Code generation. See IEP-0002 for details on Meta-Code generation.

JSON Schema: isbn.json

Example

{
  "$schema": "http://purl.org/iscc/schema/isbn-0.8.0.json",
  "isbn": "9789295055124",
  "productform": "EA",
  "title": "The Never Ending Story",
  "language": "eng",
  "imprint": "Penguin Classics",
  "publisher": "Penguin Random House",
  "country": "US",
  "pubdate": "20240214"
}

Recommended Format¶

For Meta-Code generation (IEP-0002), use compact JSON with a $schema reference. The @context and @type fields are not required - they can be recovered from the schema on demand via Schema-Driven Context Recovery.

This is fully conformant with IEP-0002, which accepts both application/json and application/ld+json as meta element formats. The compact form keeps data lean while remaining self-describing through the $schema link.

Required fields: $schema, isbn, productform, title, language, imprint, publisher, country, pubdate
