This page discusses how to configure metadata describing your data set as part of a qube-config.json file.

For a detailed look at metadata configuration options, see the Reference table at the bottom of this page.


Experience of writing basic JSON documents is assumed throughout this document. See this tutorial from DigitalOcean for an introduction to writing JSON.


All csvcubed outputs contain metadata which makes it easier to discover data publications. We use definitions from established vocabularies to enable you to contribute faster to the web of data.

The following is an example of a metadata section from a qube-config.json about Eurovision performances by Sweden, that uses all possible metadata fields.

    "$schema": "",
    "title": "Sweden at Eurovision",
    "summary": "List of Swedish entries to the Eurovision Song Contest since 1958.",
    "description": "Sweden has been competing in Eurovision since 1958, with an enviable track record of wins. This dataset covers all contests since 1958, their artists, the song names, language (if mono-lingual), and some observations covering points in final, rank in final, and number of artists on stage. Data originally sourced from and",
    "license": "",
    "public_contact_point_uri": "",
    "themes": [""],
    "publisher": "",
    "creator": "",
    "dataset_issued": "2022-04-08T00:00:00Z",
    "dataset_modified": "2022-04-08T00:00:00Z",
    "keywords": [
        "Song Contest",
        "European Broadcasting Union"

Note how some field contents must be given in square brackets [] as a list, such as keywords or themes.

You do not have to provide all fields for the metadata to be valid, but you should provide a $schema so that csvcubed can recognise the file.
