12.4. Services Discovery

The Universal Description Discovery and Integration (UDDI) specification described in Chapter 10 provides the way to advertise and discover web services; however, it doesn't support all possible patterns of discovery. It's often compared with Yellow Pages, but people don't always use the Yellow Pages to find services they need: they may already know about the service existence, but don't know the details; they may get the new service from the service provider they already use; or they get referral from people they know. While it's possible to implement these patterns using UDDI, it isn't the best tool for the job. The Web Services Inspection Language was proposed to fill the niche.
