Wikidata:Property proposal/identifier shared with
[edit]
Originally proposed at Wikidata:Property proposal/Authority control
| Description | Qualifier, to be used on external identifier IDs, indicating another Wikidata item is also matched to this ID |
|---|---|
| Data type | Item |
| Example | Creoda of Mercia (Q743095) PASE ID (P2625) 2403 → "identifier shared with" Creoda of Wessex (Q5184195) |
- Motivation
There are times when authoritative external websites and databases will differ as to whether descriptions in different original sources should be taken to refer to the same item or to different items (eg for people, in ancient documents, described in not quite equivalent contexts, perhaps with slightly different name spellings). Sometimes we will have one item in such a case; sometimes we will have two -- perhaps linked by said to be the same as (P460), sometimes not (eg if a website appears definitely to have made a mistake).
This qualifier is to indicate the other wikidata item(s) linked to the same identifier in the external database, in cases where we have multiple different items, but the external database identifies them together under the same identifier. Jheald (talk) 16:34, 18 February 2017 (UTC)

Support --Vladimir Alexiev (talk) 15:41, 23 February 2017 (UTC)- How is this different from said to be the same as (P460)? Andy Mabbett (Pigsonthewing); Talk to Andy; Andy's edits 21:08, 25 February 2017 (UTC)
- Hi @Pigsonthewing: the most important difference is that this would be a qualifier to go on particular external IDs; whereas said to be the same as (P460) is a general property on the item. From P460 one cannot tell whether a particular database merges the two identities or not; and the phrasing of P460 doesn't make it a natural for the qualifier role.
- For the record, also it may not be the case that this qualifier implies that the item should have a P460 -- it could just be a database error; the appropriate property on the item could be different from (P1889). I would prefer to leave P460 for instances where there really does appear to be a reasonable case, preferably set out at length in a reliable source, for identifying the two items with each other.

- Support this really would be useful in my view, having worked with several external id's that had issues like this. ArthurPSmith (talk) 18:32, 14 June 2017 (UTC)
