# How to find list of curated datasets

How does one find a list of all curated datasets in Mathematica? For instance, I was seeking representative reflection spectra of various types of fruit, and searched through the entity foods, but could not find any spectra. I tried natural language input, but failed, not knowing whether my query was wrong or the dataset did not exist. Likewise for atomic spectra and several other possible datasets, such as fine art paintings, automobiles, and so forth. Is there any way besides hunting through EntityValues[]?

I think EntityValue is more or less it, so this is not really an answer. However, I sometimes find fooling around with InputForm and the natural language interface useful. Here is an example.

I give InputForm that the argument the natural language interface returns after I type in the string "art paintings" and I get

That tells me something about how I should do queries on famous paintings.

This is helpful when it works, but it doesn't always. I find the natural language interface quirky and using it can often be frustrating.

• Thanks. I find the natural language interface occasionally useful when I've forgotten an obscure syntax, enter the natural language query and receive the Mathematica function call. As for curated databases... Suppose I wanted the optical reflectance spectrum of human skin. How would I search, and how would I know that (apparently) this is not in any curated databases? So +1 for you (but still no check). – David G. Stork Dec 20 '16 at 18:48
• Thanks for the up-vote. I didn't expect an acceptance. This answer only offers a crutch, not a cure. I don't think there is a cure. The issue you are raising is one of several that contribute to making it a pain to use curated data. – m_goldberg Dec 20 '16 at 19:16
