When a repository/set is validated it receives a score, which is an indication for the DRIVER technical team and the repository manager how well the specific repository or set abides to the DRIVER guidelines.
Below you will find a short description and explanation to see how the scoring mechanism works. If you have more questions or need further explanations please contact the DRIVER helpdesk.
Score calculation
Each rule is assigned a weight. The score is estimated as the weighted average of the percentage of errors for each rule.
For example, for rules r1, r2, r3 with corresponding weights w1, w2, w3, if the percentage of errors is p1, p2, p3, then the score is calculated by the following formula:
score = (w1*p1 + w2*p2 +w3*p3) / w1+w2+w3
