  1. Vocabulary and Ontology Standards for SOA and Domain Services Working session/Panel Discussion December 11, 2007 OMG SOA SIG meeting

  2. Agenda • Need for SOA Ontology, potential benefits, Categories of Services • Case for Business Services in Insurance • Case for Healthcare • Candidate OMG standards • Next Steps • Develop a RFP to define SOA Ontology? • Develop a RFP to define Ontology of Insurance Services? 2

  3. Need for SOA Ontology Reality Check: ‘Not All Services are Created Equal’ • Very soon an organization will end up with a ‘large’ number of Services (mostly bunch of ‘Web Services’) and the ‘Versions’ of each Service • Such a ‘Pile of Services’ neither serves Business nor IT very well • Can not effectively explain level of reusability, functionality, cost to business looking to fulfill new requirements • Cannot effectively assess level of composition achievable • Success/maturity/automation of SOA efforts will benefit from SOA Ontology • There does not seem to be an industry standard Ontology of Services

  4. Potential Benefits • SOA Ontology could: • Facilitate common understanding of Services (coupled with a vocabulary of Terms described in a Natural Language) available across ‘Consumers’ and ‘Providers’ of Services • Help explain to business stakeholders what Services are available to support given Business Processes • Enable discovery and execution of Services by ‘Software Agents’ resulting in further automation of SOA based platforms (machine interpretation is a key feature) • For automation (Straight Through Processing -STP) and scalability of SOA Event, Process and ‘domain Information’ Ontologies are equally important • Domain Information such as Healthcare, Insurance, financial Services…

  5. Where is Ontology needed for SOA? • Architecture view • Service Description Model • Service Visibility Model • Interacting with Services Model • Policies and Contracts Model • Governance Model • … • Business view • Stakeholders and Participants Model • Needs and Capabilities Model • Resources Model • Social Structure Model • …

  6. Insurance Use Case – Cindy Maike, Don Allen (OMG Insurance WG members) • Healthcare Use case – Ken Rubin

  7. Candidate OMG Standards ODM • Develop Ontologies of Services, associated Processes, Service Payload… • Targeted to modeling savvy audience • Modeling tools such as UML tools with ODM add-on or Ontology modeling tools • Forward engineer output as RDF, OWL, ??? • Used by ‘Reasoning Engines’, Software Agents… SBVR • To define Services in Natural Language by Business stakeholders/SMEs, Analysts • Not modeling savvy audience • Web based tools (supporting SBVR) to enable define/search of available Services • Document Rules for Services in a natural language but formal enough to forward-engineer simple Services • Export as XMI? to SOA repositories, modeling tools UPMS • To model Service metadata

  8. Next steps • Establish a team of SOA SIG, Ontology PSIG, Insurance WG, Healthcare DTF members and ??? to develop: • RFP for SOA Ontology • Who wants to get involved • RFP for Insurance Business Services • Services to support Claim Management • Who wants to get involved • Deeper dive into what Healthcare DTF (HSSP Project) is doing and leverage their work/lessons learnt
