Appendix D: Masking Action Set
The “masks” action set is masking some patterns to avoid replacements. When matching, the matching string is kept. The actions are given in the following. Please note that the numbers in { } brackets give the number of subsequent elements.
- 978-<NUMBER>-<NUMBER>-<NUMBER>-<NUMBER>{1}<NO_NUMBER>: avoid ISBN replacement
- 979-<NUMBER>-<NUMBER>-<NUMBER>-<NUMBER>{1}<NO_NUMBER>: avoid ISBN replacement
- <NUMBER>-<NUMBER>-<NUMBER>-<NUMBER>{1}<NO_NUMBER>: avoid ISBN replacement
- ISSN <NUMBER>{4}-<NUMBER>{4}: avoid ISSN replacement
