  2. Contents Discussion History Background and Motivation Goal and Purposes Framework Scope Understanding with an Example Issues Future Plan Issues for Procedure for the Specification of Web Ontology (PSO)

  3. Discussion History • The idea of this proposal has been presented in the following meetings • SC32 Joint Study Period, Clearwater, Florida, USA, January 2007 • SC 32 Plenary and WG Meetings, New York, USA, May 2007 • SC 32/WG 2 Interim, Seoul, Korea, December 2007 • SC 32 Plenary and WG Meetings, Australia, May 2008 • Extension of the Study Period and Change of its Direction • SC 32/WG 2: Workshop on ROR-ODMS-SMMP Study Periods, Wuhan, China, November 2008 • WG2 N1177: Extending the Metadata Registry for Semantic Web • SC 32/WG 2 Interim, Portugal, November 2008 • WG2 N1219: Extending the Metadata Registry for Semantic Web: Subtitled “PSO: Procedure for the Specification of Web Ontology” Issues for Procedure for the Specification of Web Ontology (PSO)

  4. Discussion History (cont.) • The idea of this proposal has been presented in the following meetings • SC 32 Plenary and WG 2 Meetings, Jeju, Korea, June 2009. • Approved as a subdivision of ISO/IEC 20943 Part 6 • SC32 N1887 JTC1/SC32 Plenary Resolutions, 2009-06-26: 32N1887-SC32_Jeju_plenary_resolutions.pdf • SC32/WG2 N1283 Presentation on Procedure for the Specification of Web Ontology: WG2_N1283_Presentation_EMDR-Korea.ppt • SC 32/WG 2: Wuhan Study Period Meeting on ROR, ODMS, PSO, SQL/MM-8 MDR, Wuhan, China, August 2009. • SC32/WG2 N1313 : WG2_N1313_WHU_ROS_09_019_MeetingMinutes.pdf • Discussion on the comments from Canana (SC32/WG2 N1291) Issues for Procedure for the Specification of Web Ontology (PSO)

  5. Background & Motivation Ontology Semantic Web Syntactic Web Evolution Ontology Ontology Specifying Web ontology using common/standardized concepts in MDR for the Semantic Web MDR (Metadata Registry, ISO/IEC 11179) Contains standardized (common) concepts for various applications fields Issues for Procedure for the Specification of Web Ontology (PSO)

  6. Goal and Purposes • The goal of this proposal is • to provide the Specification support of ontology using the conceptsin MDR • The purposes of this proposal are to promote the followings: • Faciliation usability of MDR under the Semantic Web environment • Building of ontology schema consisting of standardized concepts • i.e., well-known concepts or generalized concepts, which are accepted by general users as well as domain experts • Easy and clear understanding of concepts across corresponding same or similar application fields • More formalized building of ontology • Ease of definition (building) of ontology • Enhancement of interoperability between ontologies Issues for Procedure for the Specification of Web Ontology (PSO)

  7. Scope • This Part of ISO/IEC 20943 • covers procedures (method or guidance) for the specification (building) of ontology based on ISO/IEC 11179 (2nd Ed.) • This part is based on only the second edition of ISO/IEC 11179. • provides just a method to use concepts in MDR for building ontology • e.g., How to utilize MDR to define a Concept for an ontology • This part does not contain ontology building methods by a specific ontology description language, such as RDF, RDF-S, OWL, Topic Maps, KIF, and so on Issues for Procedure for the Specification of Web Ontology (PSO)

  8. Framework Web Ontology Metadata Registry (ISO/IEC 11179) DEC OC CD . . . DE realized MDRs (Sets of concepts) build EDR caDSR METeOR Our Proposal Scope of this Part (Metadata Online Registry) (Environmental Data Registry) (US National Cancer Institute) utilized Process Manager Mapping Info. and Rulus Issues for Procedure for the Specification of Web Ontology (PSO) 8

  9. Understanding with an Example • MDRsample = (CD, OC, Property, DEC, DT, Rel) • DT: Data types • CR: Relations between Classes • CD = {Student, Professor} • OC = {GraduateStudent, FullProfessor} • Property={name, age, address} • DEC = {GraduateStudent.name, GraduateStudent.age, FullProfessor.name, FullProfessor.age, FullProfessor.address} • DT = {String, int} • Rel = {advise, advised} Issues for Procedure for the Specification of Web Ontology (PSO) Status Report of the Study Period on Procedure for the Specification of Web Ontology

  10. Understanding with an Example (cont.) String int String age address name FullProfessor advised GraduateStudent advise name age String int An Ontology Example Generated Issues for Procedure for the Specification of Web Ontology (PSO)

  11. Issues: Scope • Scope of this Part • covers procedures (method or guidance) for the specification (building) of ontology based on ISO/IEC 11179 (2nd Ed.) • This part is based on only the second edition of ISO/IEC 11179. • provides just a method to use concepts in MDR for building ontology • e.g., How to utilize MDR to define a Concept for an ontology • This part does not contain ontology building methods by a specific ontology description language, such as RDF, RDF-S, OWL, Topic Maps, KIF, and so on Issues for Procedure for the Specification of Web Ontology (PSO)

  12. Issues: Scope (cont.) • There are two comments related with the scope of this part • This part first considers the ongoing work on 11179-3 (3rd Ed.) • from Canada for the Wuhan meeting, August 2009. • This part considers the ongoing work on 19763-3 (2nd Ed.) • from the Wuhan Study Period meeting Issues for Procedure for the Specification of Web Ontology (PSO)

  13. Issues: Scope (cont.) Standardized This Part (20943-6) Revision of this Part Considering MDR-3 (3rd), MFI-3 (2nd), & Hamornization ISO/IEC 11179-3 (3rd Ed.) New subdivisions (for MDR-3 (3rd) and MRF-3 (2nd)) ISO/IEC 19763 MFI-3 (2nd Ed.) New Project Harmornization effort of MDR and MFI Established a Strategy for Harmization • Korea suggests that with the following reasons, we'd better first develop this part 20943-6: PSO based on MDR (2nd Ed.) • Now there is an effort to harmonize MDR and MFI. • MDR-3 (3rd Ed.) and MFI-3 (2nd Ed.) are under development. • We need to support the existing MDR systems developed based on ISO/IEC 11179 (2nd Ed.) Issues for Procedure for the Specification of Web Ontology (PSO)

  14. Issues: Usage of “Specification” Issues for Procedure for the Specification of Web Ontology (PSO)

  15. Issues: Project Title • Current Title • Procedure for the Specification of Web Ontology (PSO) • Canana Input: SC32/WG2 N1291 • Since the proposal deals with specifying Ontologies based on MDR, we suggest this should be reflected in the project title. • A simple change to the existing titles, removing ‘Web’ and inserting ‘MDR-based’ gives: • Framework for MDR-based Ontology Specification • Procedure for MDR-based Ontology Specification • However, is it the Ontology or the Specification that is MDR-based? Perhaps the following would be better: • Framework for MDR-based Specification of Ontology • Procedure for MDR-based Specification of Ontology • Suggestion from the Wuhan Meeting, August 2009 • The group suggests a name such as: • Guidance for Building Ontologies based on 11179-3 MDR and 19763-3 MFI Issues for Procedure for the Specification of Web Ontology (PSO)

  16. Issues: Project Title (cont.) • Korea Suggestion • We agreed that the word “Web” is removed from the original title • 20943 family is based on ISO/IEC 11179 MDR.: 20943 project title is “ISO/IEC 20943, Information Technology -- Procedures for Achieving Metadata Registry Content Consistency” • Therefore, we don't need to name using such a modifier “MDR-based” or “Based on 11179-3 and 19763-3 MFI“ • We need to follow the naming rule of 20943 family for providing conisistency • Titles Suggested: • Framework for Building of Ontology (-gies) • Procedure for Buidling of Ontology (-gies) • Guidance for Building of Ontology (-gies) Issues for Procedure for the Specification of Web Ontology (PSO)

  17. Issues: Additional? Issues for Procedure for the Specification of Web Ontology (PSO)

  18. Future Plan • After this meeting, 1st Working Draft will be submitted • 1st Working Draft will reflect the decisions and comments from this meeting • Submission Deadline? • After this meeting ~ December 2009 Issues for Procedure for the Specification of Web Ontology (PSO)
