Transport & mobility - data quality

Lately I have been looking at data quality in the transport & mobility sector.

Helpfully UK Gov has 6 "Core data quality dimensions":

1. Completeness
describes the degree to which records are present

2. Uniqueness
describes the degree to which there is no duplication in records

3. Consistency
describes the degree to which values in a data set do not contradict other values representing the same entity

4. Timeliness
describes the degree to which the data is an accurate reflection of the period that they represent (and that the data and its values are up to date)

5. Validity
describes the degree to which the data is in the range and format expected

6. Accuracy
describes the degree to which data matches reality

These terms are use across UK Gov and were created with the UK Data Management Association https://www.dama-uk.org/
