The Generic Statistical Information Model (GSIM) is now used to identify the types of changes made to the classification. Real changes (RC) are those affecting the scope of the existing classification items or categories, whether or not accompanied by changes in the title, definition and/or the coding. Virtual changes (VC) are those made in coding, titles and/or definitions, while the meaning or scope of the classification item remains the same. The "real changes" are the most important ones to note for analysis.
Only Field Of Research (FOR) were subject to changes and are included in the correspondence table for this version of the classification.
