Relationship

The Web

The Universe of network-accessible information

XML

A universal language for structured documents and data on the Web

A W3C Recommendation and one W3C activity of many

Web

On the Web == has a URI

• Documents, of course
• People - indirectly
• Anything - indirectly

XML

• Namespaces => element types have URI (...)
• Elements have URIs
• Concepts in data and documents have URIs
• everything can have a URI
• URIs still not completely integrated with XML

Namespaces remove ambiguity

Why these terms must have URIs

• Anyone can make one
• Independent invention of concepts
• Retrospective documentation of equivalence

Universal space ...

...allows mixing

URI space

• Think of names, not addresses
• Think about persistence of URIs
• Make sure everything of importance has one

Building the future

Business reasons

A mental leap to when semantic links are everywhere

• Exposing data to analysis E.g. Compatability of parts in catalog
• Evolution of ontologies
• Representing Trust on the web

Using XML on a shelf doesn't count. Use it on the Web.
