Shortcuts: WD:M, WD:MERGEHelp:Fletting
 | Denne siden i et nøtteskall: Når du fletter elementer, sjekk at de handler om det samme, og bruk så tilleggsfunksjonen for fletting. Ikke flytt påstandene manuelt, ellers vil det ikke bli opprettet en omdirigering. Spør om du er usikker. |
En fletting utføres når to eller flere elementer på Wikidata handler om det samme emnet, konseptet eller objektet. En fletting er en flerstegsprosess som krever at alle dataene om elementene samles på én side, eller mottakerelementet, og til slutt fører til at det utgåtte elementet blir omdirigert til den nye siden.
En fletting kan gjøres automatisk eller manuelt ved å flytte sidelenker og påstander til ett element, og så omdirigere det utgåtte elementet. Automatiske flettinger med tilleggsfunksjonen for fletting er den enkleste metoden.
Denne veiledningen forklarer hvordan du kan slå på automatisk fletting ved å aktivere flettingstilleggsfunksjonen i innstillingene dine eller med verktøyet Special:MergeItems. Om dette feiler forklarer den også hvordan man kan utføre en manuell fletting.
If you have any questions about merging items, feel free to ask them on the Project Chat.
 | Advarsel: Wikidata item IDs are designated as persistent identifiers. Therefore, merged items should be redirected. Never reuse merged items for other things. |
Sjekk for å være sikker
Vær sikker på at elementene faktisk handler om samme emne, konsept eller objekt. Det kan være små nyanser som gjør at det er nødvendig med to elementer.
Eksempler
- en:tree → de:Baum (tysk for «tre»)
- Flette?
- Årsak: Disse handler om det samme («tre») og bør flettes til et (flerspråklig) element, tree (Q10884)
- en:tree → de:Eichen (tysk for «eik»)
- Flette?
- Årsak: Disse ligner, men er litt forskjellige, og bør forbli to forskjellige elementer; tree (Q10884) og Quercus (Q12004) respektivt.
- Miller (family name) → Miller (disambiguation page)
- Merge?
- Reason: These are different concepts, even if some Wikipedia articles include family names on disambiguation pages. They should remain separate as two items; Miller (Q1605060) and Miller (Q304896), respectively
Om du er usikker (for eksempel om det er vanskelig å forstå forskjellige språk), eller du kommer over elementer som er inkonsistente, er det best å føre opp saken på interwikikonfliktsiden.
Automatisk fletting
There are two ways to perform an automatic merge: the Merge gadget or the Special "Merge two items" page.
Please bear in mind, that while automated merges will be terminated if an interwiki conflict is found, you should still always check that the items are the same since the tools simply perform merging that you select to be done. Special:MergeItems can resolve conflicts that are merely due to redirects.
Tilleggsfunksjonen for fletting
Merge.js is a gadget by Ebrahim that helps moving sitelinks, labels, descriptions, aliases, and statements with references.
To enable this function, open Preferences, select Gadgets, check the box for Merge and hit the Save button. To use it, open either the recipient or obsolete item, go to the drop-down menu in the top bar (in the default skin, it is to the left of "Search"), select "Merge with...", and enter the ID of the other item into the merge wizard. Click on "Merge" when done.
Special:MergeItems
Special:MergeItems can be used to trigger a merge of two items where all labels, descriptions, aliases, sitelinks and statements are moved. Enter the Q#### (not item label) in the fields specifying which is the recipient item ("The ID to merge to") and which is the obsolete item ("The ID to merge from").
If you need assistance with the special page, please use Wikidata:Project chat.
Special:MergeLexemes
Special:MergeLexemes can be used to trigger a merge of two lexemes if (only if) the lemma, the language and the lexical category are identical. If one of them isn't identical, it may be that this can be corrected first.
Enter the L#### in the fields specifying which is the recipient lexeme ("The ID to merge to") and which is the obsolete lexeme ("The id to merge from").
QuickStatements
The QuickStatements 2 (Q29032512) tool, and its predecessor, QuickStatements (Q20084080) allow users to merge a series of items. See the instructions.
Mark as duplicate
If two items can't be merged because of two different articles at a Wikipedia, these can be marked for merging with markasduplicate.js.
The script also adds instance of (P31) = Wikimedia duplicated page (Q17362920) to the redundant item.
Manuell fletting: steg for steg
Manual merge steps (automatic merge is generally preferred) |
|---|
Velg mottakerelementNår det er bestemt at to eller flere elementer bør flettes vil ett element velges som mottakerelement (altså det du fletter inn i) for sidelenker og påstander. Mottakerelementet er vanligvis det som brukes oftest (mulige indikatorer er det som har flest sidelenker eller påstander). Når du er i tvil er det best å velge elementet med lavest Q-nummer, siden det er eldst.
Flytte sidelenkerSidelenker kan flyttes manuelt fra ett element til et annet ved først å fjerne lenka fra det gamle elementet (det du fletter fra) og så legge det til i mottakerelementet. Om du prøver å legge til sidelenka til mottakerelementet før du fjerner det fra det gamle elementet vil du få en feilmelding. Det er en tilleggsfunksjon i innstillingene kalt «Flytt» som gir brukere muligheten til å flytte sidelenker raskt. Når tilleggsfunksjonen er slått på, gå til det gamle elementet, velg sidelenkene du ønsker å flytte, klikk «rediger» fulgt av «flytt», og skriv inn Q-nummeret til mottakerelementet.
Flytte etiketter og beskrivelserCorrect labels, descriptions and aliases that are present in the obsolete item, but not present in the recipient item, should simply be added to the recipient item. If a different label is already present, you can add the label of the obsolete item as an alias. To check which labels, descriptions and aliases are present in various languages, it is advisable to turn on the labelLister gadget in your preferences. To activate the labelLister gadget for a given item, click on the "Label List" tab at the top right of the item page. Upon clicking on it, you will see a pop-up with a list of all labels, descriptions, and aliases available by language code. The autoEdit gadget (also under preferences) can in some cases be used to generate new labels and descriptions for the recipient item, which may be easier than moving them from the obsolete item. Once activated, the gadget will appear in the left sidebar menu under "Tools" with the label "Automatic addition."   
Flytte påstanderCorrect statements that are present in the obsolete item, but not present in the recipient item, should simply be added to the recipient item. Be sure not to add statements that are already present but keep in mind that it's possible to add multiple values to one property in Wikidata.
Oprette omdirigeringOnce all the sitelinks, properties, labels, and descriptions have been moved and copied over to the recipient item, the obsolete item can then be redirected. The Merge gadget provides the easiest way to do this. Redirects can also be created using Special:RedirectEntity. Furthermore, User:PLbot will create redirects for all merged items which are not redirected yet (Task 10). |
Items to be merged with sitelink conflicts
If there is a sitelink conflict, items can't be merged as only one link per site is possible.
Until the two pages at the site (e.g. articles at English language Wikipedia) are merged, two items have to be kept at Wikidata.
- One of the two items should be marked with instance of (P31)Wikimedia duplicated page (Q17362920) and qualifier of (P642)the other (main) item. Usually the more recent item should be marked. Wikidata:Database reports/Identified duplicates lists all such items.
- Statements, other sitelinks and labels/descriptions can be moved from the redundant item to the main item.
- Once the articles at the site are merged, the two items can be merged and instance of (P31)Wikimedia duplicated page (Q17362920) deleted.
Note the tool Mark as duplicate above.
If the sitelink conflict is due to an article and a redirect pointing to the same article, the redirect can be removed and the items merged.
Dealing with items where both have a Wikipedia link to the same Wikipedia
A Wikidata item can only have one Wikipedia link so it's not possible to re-add both links after merging. If one link is to a redirect and the other is to a proper Wikipedia article, then remove the link to the redirect and merge. If, however, both links are to proper Wikipedia articles, you should not leave any of those Wikipedia articles without a linked Wikidata item. Sometimes that means moving the Wikipedia link to a more appropriate item. Other times it means asking in Wikipedia for the articles to be merged when they are duplicates. If Wikipedia doesn't merge their articles, we don't merge the items here on Wikidata.
Hvor kan jeg finne elementer som trenger fletting?
Now that you know how to merge, you can make use of your new skill at various places on Wikidata where potential duplicates are found/listed. These places include:
- Wikimedia tool which has gamified the merging process, offering candidate pages to potentially be merged by the user
User:Ivan A. Krestinin/To merge
- lists of merge candidates based on similar page title strings
- lists of merge candidates based on sitelink names being identical
- lists of merge candidates based on values of a property being same in two items
- finds items containing only one sitelink to a Wikimedia site (which therefore may need to be merged with other items linked to different Wikimedia language versions of the same page)
- lists items in a given category that are linked to articles in Wikipedia A but not in Wikipedia B
- summary of constraint violations for properties; in particular, "Unique value" violations may indicate a duplication
- list of items having at least one sitelink which is due to a bug used in another item
Wikidata:Database reports/identical birth and death dates
- based on date of birth (P569) and date of death (P570)
Wikidata:Database reports/Identified duplicates
- items with Wikimedia duplicated page (Q17362920) waiting for Wikipedia to merge
Wikidata:VIAF/cluster/linking to multiple Wikidata items
- items which, according to VIAF (see VIAF ID (P214)), are related to the same person - VIAF may sometimes be wrong
Other pages and projects in the Category:Merge candidates
Feel free to add any more useful pages or delete ones that are not actively updated!
Unmerging
Canceling a wrong merge could be done in a few steps:
- Go to the history page of the item onto which the merge has been done and restore the revision just before the merge.
- Go to the history page of the merged item and restore the revision just before the merge.
The order is important (especially if the item has sitelinks) because articles can be linked to at most one item. So they should first be deleted on the item which got all the linked before they could be restored on the other one.
Some bots (KrBot for example) are known to replace the redirected items in statements with their target redirects a certain period of time (24 hours for KrBot) after the merge. The next step is to ping bot owners (like Ivan A. Krestinin) so they can run the code to cancel the merge if that period of time passed and some bot did the substitution, so that the statements can be restored with the right item. KrBot creates edit groups when fixing redirects, which may be reverted en masse using the EditGroups tool.
On a closely related topic, the help page Help:Split an item will help you if the item has not been merged but if statements on two topics are mixed-up on a unique item for some reason. It has guidelines on how to divide the statements on two items without re-entering the information by hand.
