WEID Specification

An Object Identifier (OID) is an extensively used identification mechanism jointly developed by ITU-T and ISO/IEC for naming any type of object, concept, or “thing” with a globally unambiguous name. (More information about OIDs can be found at www.oid-info.com)

The construction of a WEID is demonstrated with the example OID 2.999:
