Report of TWG Ontologies: Landscape of Ontologies Standards


In the beginning years of the evolution of the semantic web and linked data, ontology engineering made steady progress through academic efforts to support the semantic web stack. The admission of Ontology and Graphs in the “hype cycle” by Gartner’s report in 2020 not only indicated its closeness to maturity but also highlighted that Ontology is finally being accepted as a practical solution for many ICT applications.

The Technical Group for ICT under the European Observatory for Standardisation (EUOS) formed a special interest group comprising domain experts, ontologists, and researchers from academia and industry with the aim of surveying the landscape of Ontology standards.

After months of effort, 2026 community is delighted to present this report, which contains a set of carefully curated ontologies based on their relevance to ICT domains and vertical sectors, as well as their maturity and prominence for representing of linked data in the semantic web. One of the primary motivations of this report is therefore to present the landscape of ontology coverage in various domains and sectors.
