Universal Commerce Language and ProtocolUCLP is an XML-compliant schema for tagging metadata that can be used in identifying and retrieving data residing across the Internet. The tags provide a base level of data typing while allowing industry-specific names to be defined as necessary to describe those properties and attributes which a user needs when discriminating among available choices. The introduction of data typing has been discussed as a needed extension to the XML 1.0 Recommendation, but UCLP is intended to introduce a new paradigm for dynamic data tagging for which data typing is only a required tool.(Definition copied from the original specification document)
