Agenda RDF intro Problem space Demo Real Software ASYDEO Ontology Learn about how we built it

RDF != XML “ The site at also known as Travelocity, is an online travel agency competing with expedia.com”

Conceptual Model Travelocity.com AKA Travelocity Is a Online travel agency Has competitor Expedia.com

Same concepts serialized as “N3” :OnlineTravelAgency a owl:Class. :hasCompetitor a rdf:Property. a :OnlineTravelAgency ; rdfs:label ; :hasCompetitor.

As RDF/XML… Travelocity

As N-Triples canonical format…. Subject, Verb, Object…

And finally, as Java code… OntModel m = ModelFactory.createOntologyModel(); OntClass ota = m.createClass("OnlineTravelAgency"); Individual tvly = ota.createIndividual(" tvly.setLabel("Travelocity", "en"); OntProperty p = m.createOntProperty("hasCompetitor"); tvly.setPropertyValue(p, m.createResource("

Problems ASYDEO Solves If a change is made to an application, what could be impacted? Rate of change exceeds our capacity to manage documentation, is there an alternative? What URL/ports should we monitor?

How the UI works Our ontology declares a set of widgets

Each Widget has a Server Side representation

Ontology provides UI with tips for how to show each property hasModel

Path from property to java… Has editor hasModel Has type Basic DropDown Maps to Java class DropDown

In Raw RDF (N3 format) schema:hasModel a owl:FunctionalProperty, owl:ObjectProperty ; rdfs:domain schema:System ; rdfs:label "Model"^^xsd:string ; rdfs:range schema:Model ; schema:editor schema:BasicDropDown; schema:order "94". schema:BasicDropDown a schema:DropDown.

Included because RDF type is in property hasModel’s domain. schema:hasModel rdfs:domain schema:System

Candidates from the property’s range (rdfs:range schema:Model) schema:hasModel rdfs:range schema:Model

The property’s RDF Label provides human readable label text schema:hasModel rdfs:label "Model"^^xsd:string

The property’s position, relative to other items comes from ontology as well. schema:hasModel schema:order "94“ schema:hasModel schema:order "94“
