London, 1 November 2026. Compare the Cloud has published the controlled vocabulary it uses to tag its journalism, technology directory and video as open data. The Compare the Cloud vocabulary holds 1,002 concepts in six schemes (topics, technologies and capabilities, sectors, organisation roles, editorial genres and content formats), each with a definition in British English. It is released under the Creative Commons Attribution 4.0 licence and carries a permanent DOI, 10.5281/zenodo.23539653.
Every concept has a permanent web address under comparethecloud.net/vocab that serves a readable page or machine-readable SKOS data in Turtle and JSON-LD. 84 concepts carry 87 links to IPTC vocabularies, including the Media Topics standard used by news organisations, so publishers, researchers and AI developers can map their own tagging onto it.
The vocabulary is archived on Zenodo, published on Hugging Face and Kaggle with a starter notebook, registered with FAIRsharing, listed on prefix.cc under the short name ctcv and listed on BARTOC, the register of knowledge organisation systems.
“We have built Compare the Cloud on the work of the open technology community, and it is right that we give something back,” said Kate Bennett, Group CEO of Compare the Cloud. “Our vocabulary is how we make sense of a market that changes every week. Publishing it openly, with a permanent identifier, means anyone can build on it, check it or improve it.”
“Open source is how this industry grows,” Bennett added. “The companies that share their tools and data attract better people, better partners and better ideas. We want Compare the Cloud to be part of that, not just report on it.”
Alongside the vocabulary, Compare the Cloud maintains two open-source projects under the MIT licence.
DansWriter (https://github.com/danielctc/danswriter-mac) is a native macOS writing desk that keeps the draft in the centre, with word, sentence and paragraph alternatives, notes, proofreading and research alongside it. Releases are signed by Compare the Cloud Ltd and run on Apple silicon Macs.
Mental Modelling (https://github.com/danielctc/mental-modelling) is a set of sixty thinking tools in eight categories. Describe what you are stuck on and it routes you to the right tool, then works your problem through. Users bring their own API key, which stays in the browser.
Compare the Cloud welcomes corrections, suggested terms and pull requests at opensource@comparethecloud.net.
