  8. ISO/IEC 11179 and geospatial standards • 11179 • Product of ISO/IEC JTC1/SC32 WG2: Metadata • 6 parts • Freely available • Geospatial • 19100 series • ISO TC211: Geomatics (Geographic Information) • Expensive BUT some made available by gov agencies IF req’d

  9. ISO/IEC 11179 Family of standards for metadata 2000, 2005 Classification 1995, 2004 Formulation of Data Definitions 1999, 2004 Framework 1994, 2003-4, 2008? Registry Metamodel and Basic Attributes 1997, 2005 Naming and Identification Principles 1995, 2005 Registration

  11. Potential for alignment • 1 example • Registration – 19135, 11179-6 • Roles and responsibilities • Terms and definitions • Governance • Others • Metamodel • Schema • Terminologies

  12. 19135 • Divided into 8 clauses, 4 Appendices: • Scope • Conformance • Normative references • Terms, definitions and abbreviations • Roles and responsibilities in the management of registers • Management of registers • Some principles of registration • Register Schema • App. A Abstract test suite (Normative) • App. B UML Notation (Informative) • App. C Estab. of registers by ISO/TC 211 (Normative) • App. D proposals for item registration (Normative)

  13. 11179-6 • Divided into 6 clauses, 7 Appendices • Scope • Normative references • Terms and definitions • Concept of operation • Metadata Registries of Administered Items • Conformance • App. A Administered Item Identifiers (Normative) • App. B Contents of the Metadata Registry: Metadata attributes required for Administered Items (Normative) • App. C Suggested functional operating procedures — Roles and Responsibilities (Informative) • App. D Suggested functional operating procedures — Concept of operations (Informative) • App. E Suggested functional operating procedures — Procedures (Informative) • App. F Suggested functional operating procedures — Harmonization and reuse ((Informative) • App. G Frequently Asked Questions

  14. Both • Divided into 8 clauses, 4 Appendices • Scope • Conformance • Normative references • Terms, definitions and abbreviations • Roles and responsibilities in the management of registers • Management of registers • Some principles of registration • Register Schema Scope • App. A Abstract test suite (Normative) • App. B UML Notation (Informative) • App. C Estab. of registers by ISO/TC 211 (Normative) • App. D proposals for item registration (Normative) Divided into 6 clauses, 7 Appendices • Scope • Normative references • Terms and definitions • Concept of operation • Metadata Registries of Administered Items • Conformance • App. A Administered Item Identifiers (Normative) • App. B Contents of the Metadata Registry: Metadata attributes required for Administered Items (Normative) • App. C Suggested functional operating procedures — Roles and Responsibilities (Informative) • App. D Suggested functional operating procedures — Concept of operations (Informative) • App. E Suggested functional operating procedures — Procedures (Informative) • App. F Suggested functional operating procedures — Harmonization and reuse ((Informative) • App. G Frequently Asked Questions

  15. Similarities • Address registration • Address atomic item attributes—same, different • Address framework/metamodel • Address semantics • If there are these similarities between these two, what others are out there?

  16. Differences • ISO/IEC 11179 is a general standard; not subject-specific • ISO 19100 (-115, -135, -139) ARE subject-specific, but not done as extensions to 11179, but as stand-alone standards. • In some cases there isn’t a corresponding base standard for 19100 to extend • Supports “profiles” • Comprehensive • Integrated model vs component model

  17. Many similarities, some differences • BUT one is not an extension of the other • No logical relationship, so overlap? • What to do: • Harmonize • Assimilate • Crosswalk, at the very least • DON’T want to give conflicting standards advice

  18. Other relevant standards? • ebXML registry • UDDI registry • Not doing these today although they may be included in the final product;

  19. Proposal • Purpose: to harmonize and align between existing standards for registration and administration of metadata • Advantages: • Lessen the possibility of cross-purposes in interpretation • Provide clarity of purpose to users of both standards • Provide a convenient crosswalk among registration standards for reference

  20. Solutions • Houston, do we have a problem? • Lots of questions about the relative need for several of these. • Reduce risk • Improve communication • Improve standards alignment and compatibility

  21. Other potentials • Cross-pollination of ideas • Improve communication among standards organizations • Heighten awareness of other standards efforts • Less focus on subject-matter specific and more focus on generalizable principles

  22. Summary and conclusions • Register of standards and subject matter • Look for previous existing standards • Point to, don’t replicate work—extend if possible • Identify points for standards collaboration and harmonization • E.g SC32 and TC211
