What Is Needed?

A resource should provide information about itself
- also called “metadata”
- metadata stored in XML or other, machine readable form
- metadata vocabularies should be defined
- agents should be able to “reason” about (meta)data
The “Semantic Web” is a metadata based infrastructure for reasoning on the Web

It extends the current Web (and does not replace it)
