Why RDF?

• RDF is just about handling metadata!
• SKOS (not available when work began, but...)
• Data model simple and clear
• Really easy to use - espcecially with tools such as Jena (parser, writers)
• Standard

-> RDF as data model. But there's more (file format):

• simplicity (installation, management,...)
• fast response times of memory models
• easy aggregation
• pathnames on hard disk are not "cool URIs"

-> A file based RDF store is a simple and truly portable store
