Tools and frameworks to help you assess open data quality
There are two key resources which we'd recommend you utilise when thinking about assessing open data quality
5-stars of open linked data
Sir Tim Berners-Lee, the inventor of the World Wide Web and one of the ODI’s founders, suggested that there is a '5 step' deployment scheme for open data, referred to as the '5-stars of open linked data'. This framework helps data publishers to consider the legal and technical marks of quality in open data.
The 5–stars scoring system is as follows:
⭐ - Be available on the Web, in any format, under an open licence
⭐⭐ - Be in the form of structured data (eg Excel instead of an image of a table)
⭐⭐⭐ - Be in a non-proprietary file format (eg CSV file instead of Excel)
⭐⭐⭐⭐ - Use URIs to identify internet resources
⭐⭐⭐⭐⭐ - Link your data to other data to provide context
Open Data Certificates
To support publishers with assessing the practical, legal, social and technical markers of data quality, we provide a tool called Open Data Certificates. This free online tool helps you assess and recognise the sustainable publication of quality open data against established best practice guidance.
