What is the difference between wikidata and Wikipedia? Most of the red circles near me have a wikidata page, with no data, and no Wikipedia page. Plus to be honest 100% of them are business so I’m not terribly inclined to do their seo for them.
Wikidata is very inclusive. If there is a reliable public record of a thing existing (at the extreme end of the scale would be a park bench, tree, light pole) then it could be included. Wikipedia is quite selective with content included, generally requiring multiple public records documenting the thing, and for the thing to be something that the Wikipedia bureaucracy deem to be important enough to justify an article.
Hence Wikidata could have an item for every memorial park bench listed at [1] but Wikipedia just has a single page [1] describing what a typical memorial park bench is, and providing some examples either in list format or as a gallery of photos from Wikimedia Commons. Wikidata items for the memorial park benches could have properties for coordinates, official name, person or thing commemorated, date of construction, area the bench resides (e.g. park), length, height, width, construction material, identifiers assigned by heritage or government bodies, artist who designed it, benefactors who funded it, links to significant events related to the bench (e.g. used in a movie), etc.
Wiki data is meant to be some universal facts source that things like voice assistants to tap in to. Answering things like “how tall is Obama”. Wikipedia has much stricter restrictions on “notability” so most businesses won’t quality for a Wikipedia page but would be accepted on wiki data.
