Before IPsurvey allows a reference to an application database it checks the reference's language using the following algorithm;

  1. if at least one title is present 
    • if there is a title in preferred language then use it
    • otherwise 
    • if there is a title in English then use it
    • otherwise
    • set title to an empty string
  2. if at lease one abstract is present
    • if there is an abstract in preferred language then use it
    • otherwise 
    • if there is an abstract in English then use it
    • otherwise
    • set abstract to an empty string
  3. If no title and no abstract is set then discharge the reference
  4. Otherwise allow reference to the database.
