Although I am the perpetrator of the mistake, UDDI does not stand for Universial Data Description Interface, but rather Universial Description, Discovery and Integration. See www.uddi.org. UDDI is not about describing data, but about how you can find out where and how to invoke services, e.g. databases, on the web. Designed originally for Business-to-Business service discovery, we are looking at it as a registry facility for biodiversity data sources. Bob
