Greetings,
The Structured Data on Commons team plans to release the first version of qualifiers for depicts statements [0] this week. The team has been testing the feature with the community for a month [1] and are ready to turn it on for Commons on Thursday, 20 June, between 11:00-12:00 UTC. Adding qualifiers allows users to further develop depicts statements. For example, "depicts: house cat" can be extended into "depicts: house cat[color:black]." You will be able to find qualifiers in the "Structured data" tab on the file page, or in the "Add data" tab in the UploadWizard. This version has a drop-down menu to select qualifiers; an update in the near future will replace the drop-down with an auto-suggest box.
I'll keep the community posted when qualifiers go live on Thursday, after the team makes sure everything is configured and working as expected.
