5.3.5.1.4.3. Case sensitivity

| top | pdf |

The example demonstrates the way in which the application handles the case insensitivity of a requested data item. Data names are converted internally to a lower-case representation, both from the request list and the input CIF. Matches are therefore determined in a case-insensitive manner. However, if a data name is present in the CIF, its original case is retained on output. This permits the computationally irrelevant but cosmetically useful retention of capitalization as used in canonical CIF dictionary definitions. Where the requested data name is absent, the output is all lower-case.
