In computing, info is a Uniform Resource Identifier (URI) scheme which enables identifiers from public namespaces to be represented as URIs, when they would otherwise have no canonical URL form, such as Library of Congress identifiers, Handle System handles, and Digital object identifiers.
A URI that links to a JSON document can specify a pointer to a specific value. [22] For example, a URL ending in #/foo could be used to extract the value from a key-value pair in a document beginning with { "foo": ["bar", "baz"], ... } In URIs for MIME application/pdf documents PDF viewers recognize a number of fragment identifiers.

Mobile deep links are one example of a class of unofficial URI schemes that allow for linking directly to a specific location in a mobile app.
