Classification Update File (CUF)
Application
- UseCase: Automated classification updates
- NonUseCase: Viewing differences by human
Available for ECLASS Version
BASIC and ADVANCED
Definition
The main purpose of the Classification Update File (CUF) is to update classification relations for already classified products, if the classification structure has changed. This can be done by semi-automated update process that uses TUF from a previous ECLASS release to a later ECLASS release (BASIC and ADVANCED versions, XML). CUF contains the results of the changes to the classification by MOVE, SPLIT and JOIN operations, but it does not contain information about new and deleted classes.
This file is one among several supporting files (RUF, TUF, CUF, SDF) which enable a user to update an ECLASS classified and property described material master to a new version. All of these files can be found here.
