Every role, degree and project is its own node, linked to where it happened and to the skills it used, taught or certified, so a skill can always be traced back to the work behind it. Weft builds on schema.org for the kinds of things (people, organisations, roles, credentials, creative works, defined terms) and adds the relations that schema.org doesn't have, or only has as plain text. Skills can be matched to shared concepts such as ESCO or Wikidata with SKOS mappings. CV and portfolio sites, talent tools and research datasets can all use it; Graph Resume is the first application."""@en ; dcterms:creator "Rishi Rajani" ; dcterms:license ; dcterms:rights "© 2026 Rishi Rajani.
