It's interesting to contrast with Wikipedia. I'm not deeply involved with either, so I'm talking out of my ass and would be curious to hear other people's thoughts here. But Wikipedia has gone to great lengths to make the data side, Wikidata, and the app/website, decoupled. I'm guessing iNaturalist hasn't?

The OpenStreetMaps model is also interesting. Where they basically only provide the data and expect others to make Apps/Websites

That said, it's also interesting that there hasn't been any big hit with people building new apps on top of Wikidata (I guess the website and Android app are technically different views on the same thing)

I’m not convinced that that’s an accurate view of Wikidata. Wikidata is a basically disconnected project. There is some connection, but it’s really very minimal and only for a small subset of Wikipedia articles. Wikipedia is 99% just text articles, not data combined together.

Frankly, I think the reason people haven’t built apps on top of Wikidata is that the data there isn’t very useful.

I say this not to diss Wikimedia, as the Wikipedia project itself is great and an amazing tool and resource. But Wikidata is simply not there.

I am also frustrated with Wikidata. The one practical use I've seen is a lot of OpenStreetMap places' multilingual names are locked to Wikidata, which makes it harder for a troll to drop in and rename something, and may encourage maintaining and reusing the data.

But I tried to do some Wikidata queries for stuff like: what are all the neighborhoods and districts of Hong Kong, all the counties in Taiwan, and it's piecemeal coverage, tags different from one entity to another, not everything in a group is linked to OSM. It's not a lot of improvement over Wikipedia's Category pages.

Wikidata is a separate project, specifically for structured data in the form of semantic triples [0]. It's essentially the open-source version of Google's KnowledgeGraph; both sourced a lot of their initial data from Metaweb's Freebase [1], which Google acquired in 2010.

Many Wikipedia articles have infobox fields that pull their values from Wikidata (and are only editable through Wikidata).

A big part of that is that different language editions of wikipedia are very decoupled. One of the goals of wikidata was to share data between different language wikipedias. It needed to be decoupled so it was equal to all the different languages.
