- Corpus maintainers will be able to mark a sentence as "unapproved".
- Admins will be able to change the "level" of a contributor. By default contributors have a level of 0, but admins can set this level to -1 so that any new sentence/translation from these contributors are marked as "unapproved".
- Unapproved sentences will still be in the database and will still be indexed whenever we run the indexation, but will be displayed in red on the website.
- Unapproved sentences will however NOT be exported into the CSV file that we distribute.
- Bad quality sentences. We want Tatoeba to become more useful for language learners. The problem is that since everyone can contribute sentences and translations, some contributions are not reliable enough for language learning, but maybe not bad enough that it's clear they should be deleted.
- Non CC-BY sentences. It often happens that new contributors copy-paste sentences from other language learning sources. This is a problem because Tatoeba redistributes the sentences under the CC-BY license and the content needs to be CC-BY compliant.
This feature can obviously be tuned a lot more. Ideally we should treat differently the bad quality sentences from the non CC-BY sentences. Ideally we should set a different level for each user for each language instead. Ideally we should also have approved sentences, and we can also have different levels of approved and unapproved sentences. We just don't have the time and resources to implement these things right now, but they are part of the next steps.
