The alternative title section should only be used for titles that are different from the original and translated names. It should not be used to list all the different translations.
The complete guidelines for alternative titles are detailed in the Movie Bible.
To facilitate extra search, titles such as season titles and special episode titles can be added as alternative titles at the TV show level. A good example of this practice is the season titles of the series Spartacus.
The "Type" field is used for the type of title (e.g. working title, DVD title, modern title) NOT the genre (e.g. comedy).
For the sake of consistency, the "Type" field should be in English and should not be capitalized.
