Where to find meta-information about the object?

Somewhere I saw a resource with huge database about the surrounding objects, something like wiktionary.org but convenient for automatic processing, can anyone faced this thing?
The meaning is, fill up a request there, for example "python", the service provides that it may be a snake, and can be language programmirovaniya and each of these objects is tied to a specific identifier.
