Subject Classification

Capture IOP Thesaurus taxonomy codes for subject classification using a <taxonomy-group> element wrapped in a <vocabularies> element.

The <taxonomy-group> element must contain a @vocab attribute with the value IOP-Thesaurus and a @vocab-identifier with the value https://data.iop.org/iopthes

Capture each individual IOP Thesaurus code in a <taxonomy-item> element. Each <taxonomy-item> element must have:
  • A @vocab-term-code attribute containing the relevant IOP Thesaurus code
  • A @vocab-term-identifier attribute containing the relevant IOP Thesaurus code uri.
  • The IOP Thesaurus term itself in the text content of the element.
