• about browsing data on the Web
• software is very alpha
• ... but is still open source & rippable

• Lenses and views (to come)

Features

• Follows 303 redirection

• RDF/XML parser (not complete), no N3 yet
• Smush on owl:sameAs, [inverse]FunctionalProperty
• Display with subproperties of rdfs:label
• Load all ontologies (recursively)
• Load data on browse in outline view
• Load data as query binds new URIs
• List of sources: provenence

Browsable data
