Thesis

Thesis is a CreativeWork subtype for theses, dissertations, and other academic documents submitted in support of a degree or qualification. It adds 1 property: inSupportOf (the credential being supported). It lives in schema.org's bib extension (bib.schema.org), so it is stable but not part of core. All CreativeWork properties apply: author, name, datePublished, publisher, about, citation.

The type hierarchy is Thing → CreativeWork → Thesis. Use Thesis specifically for academic theses (master's, doctoral, post-doctoral). For peer-reviewed journal articles, use ScholarlyArticle. For research reports that are not theses, use Report.

inSupportOf

inSupportOf takes a Text describing the credential the thesis supports: "Doctor of Philosophy in Pediatric Medicine", "Master of Science in Computer Science". This is the thesis-specific property that distinguishes it from generic academic work.

Common Thesis mistakes

Mistakes that pass validation but silently fail to earn rich results or mislead consumers walking the graph. Avoid these and your markup will be ahead of most sites in the wild.

  1. 01

    Using ScholarlyArticle for a thesis

    Wrong
    "@type": "ScholarlyArticle" for a doctoral dissertation
    Right
    "@type": "Thesis"

    ScholarlyArticle is for peer-reviewed journal articles. Thesis is specifically for academic qualification documents (dissertations, master's theses). The distinction matters for academic search and citation indices.

  2. 02

    Missing inSupportOf

    Wrong
    Thesis with no inSupportOf
    Right
    "inSupportOf": "Doctor of Philosophy in Pediatric Medicine"

    inSupportOf is the one property Thesis adds. Without it, there is no reason to use Thesis over ScholarlyArticle. Include the formal credential the thesis supports.
