Dažām īpašībām parasti nav nepieciešamas atsauces.

In some cases sources are not typically required. This guideline explains when it is not necessary to add a source to a statement in Wikidata.

Please note that when data about an item is disputed, then a source needs to be added regardless of whether it is included below. Furthermore, sources should not be removed from items that already have sources.

Certain properties usually don't require a source:

1. many 'instance of (P31) ' values
   • where these are obvious to most human beings looking at the item
   • Example: the statement "Elvis Presley (Q303) is an instance of (P31) a human (Q5)" does not need a source
2. occupation (P106)
   • unless it is not well-known; most people, however, are notable enough to be in Wikidata because of their occupation
   • Example: the statement that "Elvis Presley (Q303) had the occupation (P106) of singer (Q177220)" does not need a source
3. subclass of (P279)
   • similar to instance of (P31) — but used when every instance of a class is also an instance of another class
   • Example: the statement "a trilogy (Q149010) is a subclass of (P279) a series of creative works (Q7725310)" (every trilogy is a series in English) does not need a source

Where the external source of information allows easy verification of the statement:

1. Wikidata:List of properties/Generic#Authority control
   • values for authority control properties do not need a source because the values are linked to and/or automatically imported from the authoritative catalog, system, or database
   • Example: a statement about Harry Potter and the Philosopher's Stone (Q43361)'s GND ID (P227) (an authority file maintained by the German National Library) or its OCLC control number (P243) does not need a source
2. Commons category (P373)
   • a statement about the item's Wikimedia Commons category (the category containing files related to the item) does not need a source
3. topic's main category (P910) and category's main topic (P301)
   • for items that are Wikimedia category pages
   • Example: a statement that the category's main topic (P301) is Germany (Q183) for Category:Germany (Q1410828) does not need a source

Note: If a particular authority control source of information has not yet been added to Wikidata as a property, you can propose it at Wikidata:Property proposal/Authority control.

1. a book for its author and other information on the cover
   • for information inside the book (e.g. plot details) use chapter (P792) in the source
   • Example: a statement about The Hunger Games (Q11679) having Suzanne Collins (Q228624) as the author (P50) does not then need to include The Hunger Games (Q11679) as a source
2. a movie for its actors and other information in the credits
3. a DVD or LP record for information on the cover, including the playlist
   • for information in liner notes use stated in (P248) with liner notes (Q2263757) as the source
4. coordinates for anything you can visit or easily identify on a map, including a lunar or Martian map.
