This is what it looks like to add today's date in Wikidata using the currentDate Gadget. It works with the retrieved (P813) property, which is usually a qualifier for Web link references.
This is what it looks like to add references with the DuplicateReferences Gadget enabled. When it is enabled, you will see a copy link next to a reference that has been added, and an insert reference link will appear as an option in the add reference space
  • currentDate: Automatically adds the date of today while using the property retrieved (P813). See GIF →
  • DuplicateReferences: Adds a link to copy references and add them to other statements on the same item. See GIF →
  • Recoin: Displays an icon at the top of the page representing the relative completeness of the item's information, and adds a dropdown list of the most relevant properties not present in the item description.
  • Drag'n'drop: Add statements and references from Wikidata or Wikipedia by dragging and dropping them.
  • Additional Gadgets and how to add them

User ScriptsEdit

  • IdentifierInput script lets you paste in a full URL value for an identifier property and automatically strips the URL down to the identifier
  • VIAF script allows you to explore the members of a VIAF cluster (codes and labels) just passing over the value of P214
importScript( 'User:Bargioni/viaf.js' );
  • moreIdentifiers script allows you to add IDs from VIAF clusters in a semi-automatic way and to report errors possibly present in the VIAF clusters themselver (i.e. a cluster regarding a subject X contains an ID regarding a subject Y); the settings of the gadget are partially customizable (see User:Bargioni/moreIdentifiers for more information)
importScript( 'User:Bargioni/moreIdentifiers defaultconf.js' );
importScript( 'User:Bargioni/moreIdentifiers.js' );
  • Duplicate Item script duplicates an item
importScript( 'User:Magnus_Manske/duplicate_item.js' );
  • Move Claim moves or copies a statement to the same one or a different one

Most statements on Wikidata should be verifiable in some source of information. They point to a source that supports the data in a statement. References have a property and value like statements. The value is the source. The property is usually:

  stated in (P248) for publications and media
  reference URL (P854) for websites and online databases
References are not required in some circumstances:Edit
  • Statement represents common knowledge that isn’t disputed
 George Washington (Q23)instance of (P31)human (Q5)
  • Statement refers to an external source of information that can be easily verified
 Mary Jo White (Q6779939)ISNI (P213)0000 0000 4948 7201
  • Item itself is a source for the statement
References for WebsitesEdit

The most common sources in Wikidata are probably websites. Use reference URL (P854) with the website as the value and retrieved (P813) with the date you accessed the website.
