I solved #16! If you are "searching" for a food or recipe based on it's nutritional contents (for example: I want foods/recipes high in potassium and selenium, but low in sodium), check out https://kale.world/c You can search by over 20 different nutrient types, weight them, and filter them to your hearts content.

Where is that data from?

Also, it looks like you republish recipes from other websites. Do you have their permission to do so?

[pascalxus]

i don't have the actual recipe, just the ingredients. With a link to their recipe. there are no instructions on our site, except their description which they publish through JSON+LD. Basically all the info we show is just stuff they publish through JSON+LD

[VectorLock]

So all these recipes are from sites that publish recipes from JSON+LD? How do you discover them?

[pascalxus]

It's the same way that google discovers them. The JSON+LD is on the recipe page. They place it there for search engines to discover it, so that they appear in a search result with the JSON+LD data: this data enhances the result, instead of just having the name of your recipe, the result contains description, image and ingredient lists.

You can see this in action on google search: type in something like "Chili soup", then it'll return the image, description, some parts of the recipe, etc.

You make it sound like somebody gives up their copyright by using a certain data encoding.

[Trundle]

What copyright? Maybe I'm missing a section but nothing on his site looks like it would fall under copyright protection.

Lists of ingredients aren't protected by copyright. Hell, neither are basic instructions and he doesn't even have those.

Photos are but this looks like it would fall under fair use. If you have a fashion blog you're allowed to use a photo of a dress from the makers website when you're writing about it. It's hard to comment on a product if you can't share a photo of the product. This guy is commenting on various foods by showing their nutritional value.

[pascalxus]

The whole point of JSON+LD is to make that information more accessible to the outside world (like to search engines), why else would they publish that?

is there any reason to think any site wouldn't want their recipe showing up in a search result?

the 2 sites I talked to were overjoyed to have their recipes shown in my search results.

You might want to research the legal cases regarding copyrighting recipes.

the Data comes from the USDA Nutrient Database which is open to the public.

[HugThem]

Ah yes, I came across that DB once. Cool.

[ThePadawan]

I have until now always used http://nutritiondata.self.com/tools/nutrient-search which has lots and lots of variables.

[pascalxus]

this one's much more comprehensive and contains all the foods: for example cream of tartar for highest potassium. Kale.world limits the food search to less esoteric choices, mostly primary ingredients, rather than including everything under the sun.

Sliders do not appear to work on iPad.

Thanks for the heads up, I'll fix that.
