  1. Applying Semantic Technologies to Asset and Configuration Management in the Enterprise Taylor Cowan Brian Boyd Travelocity.com

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

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

  4. Conceptual Model

  5. Same concepts serialized as “N3” :OnlineTravelAgency a owl:Class . :hasCompetitor a rdf:Property . <http://www.travelocity.com> a :OnlineTravelAgency ; rdfs:label "Travelocity"@en ; :hasCompetitor <http://www.expedia.com> .

  6. As RDF/XML… <rdf:RDF …> <owl:Classrdf:about="http://foo#OnlineTravelAgency"/> <rdf:Propertyrdf:about="http://foo#hasCompetitor"/> <OnlineTravelAgencyrdf:about="http://www.travelocity.com"> <hasCompetitorrdf:resource="http://www.expedia.com"/> <rdfs:labelxml:lang="en">Travelocity</rdfs:label> </OnlineTravelAgency> </rdf:RDF>

  7. As N-Triples canonical format… <hasCompetitor> <rdf:type><rdf:Property> . <http://travelocity.com> <hasCompetitor> <http://expedia.com> . <http://travelocity.com> <rdfslabel> "Travelocity"@en . <http://travelocity.com> <rdf:type> <OnlineTravelAgency> . <OnlineTravelAgency> <rdf:type> <owl:Class> . Subject, Verb, Object…

  8. And finally, as Java code… OntModel m = ModelFactory.createOntologyModel(); OntClassota = m.createClass("OnlineTravelAgency"); Individual tvly = ota.createIndividual("http://www.travelocity.com"); tvly.setLabel("Travelocity", "en"); OntProperty p = m.createOntProperty("hasCompetitor"); tvly.setPropertyValue(p, m.createResource("http://www.expedia.com"));

  9. “Understanding the relationships between systems, software, and the business processes they enable”.

  10. Ontology

  11. Travelocity Systems Knowledge • 42,000 explicit assertions.

  12. 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?

  13. demo

  14. SPARQL #1 Question: What other software does software named “air-shopping” with version “1.0” connect to? Provides service Accessed by Connects to version=“1.0” label=“air-shopping”

  15. version=“1.0” label=“air-shopping” Provides service Accessed by Connects to SELECT DISTINCT ?dstSoftware WHERE { ?srcSoftware a asydeo:ApplicationSoftware . ?srcSoftwarerdfs:label ?label . ?srcSoftware :version "1.0" . ?srcSoftware :connectsTo ?sap . ?service :isAccessedBy ?sap . ?dstSoftware :providesService ?service . FILTER regex(?label, "air-shopping", "i") }

  16. SPARQL #2 What System Services are provided by Computer System “srvhlp550”?

  17. SELECT DISTINCT ?service WHERE { ?system rdfs:label "srvhlp550" . ?system a :System . { ?system :hasInstalled ?software } UNION { ?cluster :hasMember ?system .?cluster :hasInstalled ?software } .?software :providesService ?service }

  18. Asydeo basics

  19. ASYDEO Platform

  20. How the UI works • Our ontology declares a set of widgets

  21. Each Widget has a Server Side representation

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

  23. Path from property to java…

  24. In Raw RDF (N3 format) schema:hasModela owl:FunctionalProperty , owl:ObjectProperty ; rdfs:domainschema:System ; rdfs:label "Model"^^xsd:string ; rdfs:rangeschema:Model ; schema:editorschema:BasicDropDown; schema:order "94" . schema:BasicDropDown a schema:DropDown.

  25. Included because RDF type is in property hasModel’s domain. schema:hasModelrdfs:domainschema:System

  26. schema:hasModelrdfs:rangeschema:Model Candidates from the property’s range (rdfs:rangeschema:Model)

  27. schema:hasModelrdfs:label "Model"^^xsd:string The property’s RDF Label provides human readable label text

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

  29. Future Work

  30. Auto-discovery Scripts rdf rdf rdf

  31. Some Advantages We Discovered
