 So one looks at Chiusano's Semantic Web Services Initiative (SWSI) architecture requirements for Semantic Web Services. If one is putting up a service and one wants automagical connections to be made based on the service QoS, etc., one will want to do a thorough job with the metadata because what one has may not be Googleable, and because one wants to stand out on merit. If a web service isn't a document, what else would you do except UDDI? len From: Elliotte Rusty Harold [mailto:elharo@m...] Beyond the issue of lying metadata, there's a much more important distinction between metadata based search engines like the semantic web and data based engines like Google. Providing metadata requires extra effort which is roughly proportional to the quality and amount of the metadata to be provided. There is a noticeable cost for a site to add metadata. By contrast, there is negligible cost to provide data for Google because this is the same data you're providing anyway. Metadata isn't free. The semantic web is going to need to provide really significant benefits to content authors to justify the added costs of supplying useful metadata. Even if it does, I wouldn't be surprised if much metadata is created by tools that screenscrape the data and thus guess the appropriate metadata.
