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”http://www.travelocity.com

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

5. Same concepts serialized as “N3” :OnlineTravelAgency a owl:Class. :hasCompetitor a rdf:Property. a :OnlineTravelAgency ; rdfs:label "Travelocity"@en ; :hasCompetitor.

6. As RDF/XML… Travelocity

7. As N-Triples canonical format…. "Travelocity"@en.. Subject, Verb, Object…

8. And finally, as Java code… OntModel m = ModelFactory.createOntologyModel(); OntClass ota = 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"));

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?

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

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

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 }

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… Has editor hasModel Has type Basic DropDown Maps to Java class DropDown

24. 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.

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

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

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

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

29. Future Work

30. Auto-discovery Scripts Systems Engineering (ASYDEO) Network dumps Deployed software manifests System uptime and configuration rdf

31. Some Advantages We Discovered CMDB (mysql) Flat/tabular model Code and database cognizant of ontology No restriction languageAll data must be explicit ASYDEO (Jena) HierarchicalCode is ontology agnosticOWL provides restrictionsSome data is inferred
