Topic?
I think it would be better to describe what is seen on a picture, instead of telling the topic. For example, a picture shows those Wikidata items Q35525 (White House), Q76 (Barack Obama), Q1273495 (dog Bo) and Q7777019 (meadow). But what would be the topic? pet, dog, playing, etc? It is not obvious. --Goldzahn (talk) 07:10, 4 October 2014 (UTC)
 * I guess, we need both. For example: commons:File:Into the Jaws of Death 23-0455M edit.jpg. There is seen a Landing Craft (Q1803024) and some soldiers (Q2063057, V Corps (United States)). What is missing is the date - 6. Juni 1944, -, place name - Omaha Beach and the topic - II. World War. PS: I have seen the Structured Data List - proposal. --Goldzahn (talk) 07:51, 4 October 2014 (UTC)
 * That's a thing the community has to figure out as we go along. It could be all of what you listed or just parts of it. We'll not be making restrictions there. Hope that helps. --Lydia Pintscher (WMDE) (talk) 07:43, 4 October 2014 (UTC)

Structured data
"Structured, machine-readable data": what is "structured data"? It is a machine-readable data? --Fractaler (talk) 17:36, 25 February 2018 (UTC)
 * As opposed to unstructured data, structured data has a well-defined (modelled) format. This helps make it machine readable. --Clump (talk) 17:48, 25 February 2018 (UTC)
 * Thanks for the answer. Now a new question arises: what is "well-defined (modelled) format" (that have a "pre-defined data model"?)? The term is imprecise for several reasons: "2. Data with some form of structure may still be characterized as unstructured if its structure is not helpful for the processing task at hand". Then, for example, data in "Wikidata properties" (Q18616576: "part of", etc.) can be characterized as unstructured: this tool is not helpful for the processing task at hand (provides only local, relative information: a graph of a tree type can not be obtained (for example, by "Template:Item documentation", by Template:Category tree, so it is not possible to verify transitivity). And if you use, for example, the set "part" instead of the "part of" property, then the structuredness of the data appears, the absolute path (breadcrumb) appears, the ability to check the transitivity of the data. But then we received tool like "category tree" (for example, Q1064858 (desk), Category:Desks) --Fractaler (talk) 09:52, 26 February 2018 (UTC)
