The UploadWizard allows to prefill fields like the category or campaign specific fields by adding arguments to the URL. This is a very nice feature for upload tools or templates.
Unfortunately it is currently not possible to add structured data this way. I would like to have this added.
In the URL this could be a simple &property=statements like:
&P180=Q10884
| Status | Subtype | Assigned | Task | ||
|---|---|---|---|---|---|
| Open | Feature | None | T327009 Add structured data support to UploadWizard URL arguments | ||
| Open | None | T364237 Upload wizard takes depicted element Wikidata QID as a URL parameter |
Would it be enough to support item (Q code) values? The code needs to know the datatype of each property, and we could hardcode it as "wikibase-entityid" for now. For an example, see the dataType fields in the campaign configs: https://www.mediawiki.org/wiki/Extension:UploadWizard/Campaigns#Structured_Data_in_Campaigns
If we later want to support other datatypes, those could e.g. follow the syntax of QuickStatements with strings put in quotes, coordinates with a prefix @ etc. For example: &P625=@60.18/24.95
I think items are the most important and could be a good first step. But especially strings would also be useful to hand over identifiers.
