Talend Trust Score™ overview

The Talend Trust Score™ helps you answer the question "How trustable is my dataset?". This global quality indicator aggregates several metrics into a single and easy to understand score, that scales from 0 to 5. Its evolution in the period chosen is represented with a green flag, if positive, or a red flag, if negative.

The different factors that can raise or lower the Talend Trust Score™ of a dataset can be regrouped under five main axis:

• Validity, that takes into account the quality of the dataset itself, with the number of valid and invalid values across the dataset sample, as well as the use of semantic types.
• Completeness, that depends on the number of empty records in your sample.
• Popularity overview, that gives an idea of the reliability of the dataset, via the presence of user ratings and certification level.
• Discoverability overview, reflecting how well-documented your dataset is, with the use of proper metadata such as a description, tags, custom attributes, as well as the presence of an API. A well documented dataset is easier to find.
• Usage overview, that shows how much your dataset is used as source for pipelines or preparations.
