The Hyper Text Coffee Pot Control Protocol (HTCPCP) is a protocol for controlling, monitoring and diagnosing coffee pots over a network. The Resource Description Framework (RDF) is a general-purpose language for representing information in the Web. This document defines HTCPCP Vocabulary in RDF in order to allow HTCPCP headers that have been exchanged between a client (in other words, a coffee addict) and a server (a networked device that can brew, store and deliver heated coffee beverages) to be recorded in RDF format. The objective of this vocabulary is to support quality assurance testing, and to serve as a machine-readable component in conformance claims and in reporting languages such as the Evaluation and Report Language (EARL) [EARL Schema].
