Overview
• Motivation– Demonstrate “value-add” application enabled by semantic web
technology
– Support common easily understood domain
– Gain understanding of access technologies related to DAML+OIL representations
• Selected Application– Restaurant ontology supporting repository of information
– Restaurant data maintenance software
– Itinerary ontology obtainable from travel agents
– Semantic join across restaurant and itinerary ontologies

Semantic Join
• Performed using “postal code” data property of– Itinerary ontology’s hotel location information
– Restaurant ontology’s location information
• Search performed by custom application that restricts restaurant location search based on result of hotel’s location

Summary
DAML DINING:
• Intended to demonstrate practical uses of semantic web technology in simple to understand domain
• Example application code shows “semantic join” of hotel postal code from an itinerary file with postal code of stored restaurants
• Prototype currently being updated
• XSLT technology used to support queries and formatting
