UDDI
A specification for development of global online directories and registries of Web services.
UDDI allows organizations to register their technical specifications (such as integration profiles and capabilities) and then identify the specifications of others.
This will enable universal interoperability of B2B transactions for a variety of e-business services.
Three types of information are registered:
1) Company names and primary services offered.
2) the company category based geographical location and SIC code universally used by U.S. government and United Nations.
3) company interactions with other companies.
