All data can typically be measured for Validity. Validity applies at the data item level, record level (for combinations of valid values), as well as metadata.
Unit of Measure: Percentage of data items valid.
Related dimensions: Accuracy, Completeness, Consistency and Uniqueness
Notes Data may also be valid only for a specific length of time. For example data that is generated from RFID or scientific datasets.
