Duplicates

Data quality is very important for us. Therefore, our moderation team is investing additional time to determine false-positives and potential duplicates.

In rare occasions a duplicate is added to the database. As soon as we are aware of this, we initiate the following process:

  1. Identify parent entry. This is usually the first entry that got added to the database.
  2. Merge the data of the new duplicate into the existing original.
  3. Flag the duplicate as such.
This leads to the following effect on the service:

  • The duplicate is hidden in all overview lists on the web site (e.g. recent, archive, search)
  • Accessing the duplicate will enforce an HTTP redirect to the original entry
  • Accessing the duplicate with via API shows the obsolete duplicate entry data which contains the additional data field entry_replacedby (this is the indicator that this is a duplicate that got merged)
  • Accessing the original entry with via API shows the correct entry data which might also contain the data field entry_replaces for backlinking purposes
