Constrained Internationalized Resource Identifiers are an alternate serialization of Uniform Resource Identifiers (URIs) that encodes the URI components in Concise Binary Object Representation (CBOR) instead of a string of characters. This simplifies parsing, reference resolution, and comparison of URIs in environments with severe limitations on processing power, code size, and memory size.
