Motivation

Many organizations who issue identifiers for objects also align their dataset with other identifier schemes. For instance, by resolving a VIAF ID (Q19832964), one can often find a International Standard Name Identifier (Q423048), which is supposed to refer to the same entity.

When trying find a particular identifier for some items, it is therefore useful to have in mind the directed graph of all such relations. I started drawing one for myself for International Standard Name Identifier (Q423048), but I realize it could actually be represented in Wikidata directly. I am not sure about the property name. I don't know either if it should apply to the item representing the unique identifier, or to the property used to state it. What do you think? Or maybe there is already something to do that and I have missed it? − Pintoch (talk) 22:45, 2 February 2017 (UTC)[reply]

Discussion
Actually, I think uses (P2283) would be suitable, if added to the item for the database (not the item for the identifier). Thanks! − Pintoch (talk) 13:49, 25 February 2017 (UTC)[reply]
It is not. For instance GRID provides FundRef identifiers, so I would like to state something like "GRID" "aligned with" "FundRef", but these two identifiers are not issued by the same entity. Note that this is also a directed relation (non symmetric). − Pintoch (talk) 17:58, 4 February 2017 (UTC)[reply]
How about using related property (P1659)? ChristianKl (talk) 18:40, 11 February 2017 (UTC)[reply]
It looks like it is already used in a looser sense. For instance Palissy ID (P481) links to Mérimée ID (P380): these two identifiers are issued by the same organization, and they do not overlap (one is for architecture, the other for furniture). Again, another way to detect the difference is the symmetry: I think "see also" can be roughly considered symmetric, which is not the case for the property I am proposing. − Pintoch (talk) 22:04, 11 February 2017 (UTC)[reply]
Thanks! But I don't get at all how it works. What is this VIAF component (Q26921380) item? I have never heard about "the VIAF component". Shouldn't we use VIAF ID (Q19832964) instead? − Pintoch (talk) 13:45, 25 February 2017 (UTC)[reply]
You might want to read an article about VIAF to understand what its components are.

Hum, this is not a very helpful reply. Googling for "VIAF component" returns… the Wikidata item. Can you give me a link to a page that explains what you mean by "VIAF component", in a sense that is different from just the contents of the VIAF database? − Pintoch (talk) 14:52, 25 February 2017 (UTC)[reply]
The articles about VIAF are linked from the item Q54919. It's a somewhat complex matter that may not be suitable for initial editing at Wikidata.

Are you aware that this is a rather condescending reply? I do understand how VIAF works, thank you. I was just trying to point out politely that this item is ill-defined, as far as I can tell. It is not the instance of anything, and only contains one statement "part of VIAF". Using a proxy item that does not correspond to any identifiable concept seems to be against common practice in Wikidata. This is why I challenge you to give a satisfactory definition of it, so that we could update the item. If you are not able to define what this item represents, we should delete it and replace the links to it by something else. − Pintoch (talk) 16:07, 25 February 2017 (UTC)[reply]

I propose that we cancel this proposal and use uses (P2283) on dataset items. − Pintoch (talk) 13:49, 25 February 2017 (UTC)[reply]
