The IEC 62569 series of publications defines principles and methods for the specification of objects by object properties, e.g. in data sheets, by utilizing predefined and internationally standardized (dictionary) properties residing in the data dictionary of IEC 61360 This series is prepared to transfer the former paper-based applications of blank detail specifications or product descriptions towards supporting the electronic business allowing the evaluation and management of described items by computers. This Part specifies several qualifiers to be used with object or (dictionary) properties indicating life cycle and other aspects of the property. It is a prerequisite for the usage of the other parts of this series.
