Pseudonym mapping
The pseudonym mapping page lets you look up the original data corresponding to pseudonyms that were added in the External pseudonym view. Note that the external pseudonym table is stored within a limited time frame.
1. Search field
To retrieve the original value:
- Enter the pseudonym in the search field.
- Click the Find button.
The search is case-sensitive.
2. Results
If a match is found, the result is displayed below the search field.
- The prefix [External] indicates that the match comes from the external pseudonym table, followed by the associated project.

If no correspondence is found for the pseudonym, an error message is displayed, as illustrated below.
