Primary and secondary registers

Primary and secondary registers capture all fields from source files (all fields are captured regardless of whether they are marked as interesting register columns).

A primary register is permitted to specify a class and name, noting that if multiple primary registers are defined, consolidation will determine a single winner in each case.

Classification of objects is optional, however, best practice is to ensure a default classification. Where this is not well defined, classes such as XX – Unknown Mechanical, XX – Unknown Instrument, and so on, may be defined which act as filters in which to see poorly defined information. These items may then be examined to determine whether data is incorrect or Information Standard rules require updating to cater for them. Fig.
