What is Schema.org Author Person typed with Wikidata?

It is a JSON-LD markup that declares an article's author as a Schema.org Person, with a sameAs attribute pointing to their Wikidata ID (Qxxxxx). The goal: tie a verifiable, disambiguated identity to each piece of content.

What is Schema.org Author Person typed with Wikidata, editorially?

Schema.org is an open vocabulary launched in 2011 by Google, Microsoft, Yahoo and Yandex to make web pages machine-readable. The Person type defines a person; applied to the author field of an Article or page, it turns a text signature (« by Lorenzo Eeman ») into a structured assertion. Paired with the sameAs property pointing to Wikidata, it creates the dual author-authority key that LLMs value.

Canonical architecture. On every editorial page, the JSON-LD should include a Person node with: @type=Person, name=full name, url=bio page on the site, jobTitle=role, worksFor=organisation (with its own Organization node), and, critically, a sameAs array listing external identifiers. The standard list: Wikidata Q-ID, LinkedIn, official company profile, Wikipedia page if it exists, ORCID for academic profiles.

Why sameAs changes everything. sameAs is what lets the answer engine (or Google's Knowledge Graph) resolve the same person entity across five different sources. Microsoft publicly confirmed (via Fabrice Canel) that Schema markup helps Microsoft's LLMs understand content. Resolved entities receive a higher trust score in AI answer generation. Without sameAs, a page that mentions « Lorenzo Eeman » and a page that mentions « L. Eeman » are seen as two distinct entities. With sameAs pointing to Wikidata Q139504784, they merge.

"A Wikidata item has to be solid before you point a sameAs at it: at least three to five verifiable external sources, the minimum properties filled in, and ideally a reciprocal link back to your own profiles," stresses Lorenzo Eeman, founder of PROEMA. Bilateral coupling is what makes the knowledge graph stable.

Impact measurement on the GEO Rocket portfolio. On expertcafe.be, zeroproof.one and expertvin.be, every article and FAQ carries a Schema.org Article with Person author linked to Wikidata Q139504784 (Lorenzo Eeman). Pages signed by Lorenzo Eeman reach a Perplexity citation rate 30-50% higher than equivalent anonymous pages (internal measurement, verticalised panel of 60 questions). The delta is not solely explained by the author, but the Schema Person + sameAs Wikidata pair is a measurable contributor.
