Completeness
Presence and absence of features against the specified data content*
Omission
Features representing objects that conform to the specified data content but are not present in the data
Commission
Features representing objects that do not conform to the specified data content but are present in the data
Logical consistency
Degree of adherence to logical rules of data structure, attribution and relationships
Conceptual consistency
How closely the data follows the conceptual rules (or model)
Domain consistency
How closely the data values in the dataset match the range of values in the dataset specification
Format consistency
The physical structure (syntax): how closely the data stored and delivered fits the database schema and agreed supply formats
Topological consistency
The explicit topological references between features (connectivity) – according to specification
Positional accuracy
Accuracy of the position of features
Absolute accuracy
How closely the coordinates of a point in the dataset agree with the coordinates of the same point on the ground (in the British National Grid reference system)
Relative accuracy
Positional consistency of a data point or feature in relation to other local data points or features within the same or another reference dataset
Geometric fidelity
The ‘trueness’ of features to the shapes and alignments of the objects they represent*
Temporal accuracy
Accuracy of temporal
Temporal consistency
How well-ordered events are recorded in the dataset (life cycles)
attributes and temporal relationships of features
Temporal validity (currency)
Validity of data with respect to time: the amount of real-world change that has been incorporated in the dataset that is scheduled for capture under current specifications
Thematic accuracy (attribute accuracy)
Classification of features and their attributes
Classification correctness
How accurately the attributes within the dataset record the information about objects*
