Point 4: Binding Ontologies to XML
- XML and the Semantic Web are often viewed as competing efforts.
- Identity is crucial for data merger across heterogeneous Web Services.
- The Semantic Web gives us identity through URIs and entailment.
- Need the Semantic Web to WSDL - only takes xsd types.
- GRDDL makes possible to bind ontologies to XML, but does so in a procedural manner through embedding XSLT.
- XML Schema annotations allow one to do so declaratively, which is safer and directly builds on instead of losing the original XML Infoset of the document.
- Web Services are semantically typed, and so should be their content.
