Published Revision Projects
In CPC, changes to the Scheme (and the associated Definitions and Concordance) are often published prior to the completion of the reclassification of documents. Therefore, to direct users to the symbols for search, Warnings are placed with source and destination symbols impacted by ongoing reclassification. Source groups to be deleted remain available for search as “frozen” symbols while documents are reclassified to destination groups. When reclassification has been completed, Revision Projects undergo "finalisation" in order to remove the Warnings and delete previously "frozen" symbols.
The following table provides the complete list of published Revision Projects.
