How do you differentiate between the original and the translation file?
Does the following query help you on the way to enlightenment:
```dataview
TABLE publication-date as "org date", translation.publication-date as "translation date"
WHERE publication-date
```
Now it’s tested, and verified that it looks up the value of the property publication date in the file linked by the translation property. Notice how the space in your field name is translated into a hyphen/dash/… to normalise the field name.
