Web Ontology Language VS RDF

As of 30 October 2026, RDF is named by 160 companies and Web Ontology Language by 154; Web Ontology Language skews to companies under 200 people (39% vs 37%), RDF to companies over 1,000 (40% vs 39%).

As of 30 October 2026 · refreshed daily · counts move as websites, DNS and career sites are re-read.

The website-and-DNS footprint is not comparable between a marketing suite and a CRM: Web Ontology Language's script and mail records show on hundreds of thousands of small sites, RDF rarely leaves a trace outside its own apps. Compare on the job-posting numbers; use the footprint for reach.

How we know

Read from the source, not self-reported

Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →

  • Job postingsRead hourly from career sites. A tool counts when the employer's own text names it as the team's system; both tools can count for one company.
  • Website and DNSScripts and embeds on the company's pages, plus SPF, DKIM, MX and CNAME records of its domain that point at the vendor.
  • SegmentsCountry, size and industry from the company profile built from its website.
  • Not a reviewNo ratings, prices or feature claims. For those, read the vendors.
