  1. Metadata Registry Workshop Washington, D.C., U.S.A. Considerations for Establishing and Managing A Registry for Metadata Phong Ngo (NCITS/L8 - SAIC) April 15-17, 1998

  2. Agenda • Introduction: Why register ? • Scope of ISO/IEC 11179-6 • Registration Principles • Who’s doing what to whom ? • What to register ? • Registry key issues (resolved ?) • First step first... • Info you can use

  3. Our Blessings... Our Problems • Information Revolution: Internet and other global computing facilities. • Interconnection is somewhat standardized and enabled. • Semantic content and the representation of Data Elements are NOT usually standardized thus NOT fully shareable. • Data cannot be shared if they are NOT registered and NOT available.

  4. Contributions of ANSI and IEC/ISO • ISO/IEC 11179 - Specification, Identification and Registration of Data Elements • ANSI X3.285 (to be fast tracked into ISO)-Specification, Identification and Registration of other objects such as: Object Classes, Data Elements Concepts, Properties, Data Value Domains.

  5. Agenda • Introduction: Why register ? • Scope of ISO/IEC 11179-6 • Registration Principles • Who’s doing what to whom ? • What to register ? • Registry key issues (resolved ?) • First step first... • Info you can use

  6. Scope of ISO/IEC 11179-6 This Part of ISO/IEC 11179 • defines the type of information that shall be specified, the conditions that shall be met, and the procedure(s) that shall be followed. • does NOT specify the registry's system design, file organization techniques, storage media, programming languages, etc. to be used in its implementation. • may be extended to register other shared objects, such as object classes, data element concepts, and permissible data element values (domains).

  7. Agenda • Introduction: Why register ? • Scope of ISO/IEC 11179-6 • Registration Principles • Who’s doing what to whom ? • What to register ? • Registry key issues (resolved ?) • First step first... • Info you can use

  8. Metadata Registration Principles • Non exclusive registration: Every organization may be a Registration Authority. • Data sharing registration: Data may be shared intra- or inter-organizationally. • Economically enforced registration: Utility determines longevity and usefulness. • Flexible Registration: Metadata may be registered at different levels of quality.

  9. Agenda • Introduction: Why register ? • Scope of ISO/IEC 11179-6 • Registration Principles • Who’s doing what to whom ? • What to register ? • Registry key issues (resolved ?) • First step first... • Info you can use

  10. Who’s is doing what to whom? • Registration Authority • An organization authorized to register data elements (or other objects). • Responsible Organization • The organization Or unit within an organization that is responsible for the contents of the mandatory attributes by which the data element is specified. • Submitting Organization • The organization Or unit within an organization that has submitted the data element fro addition, change, or cancellation/withdrawal in the data element dictionary.

  11. Roles and Responsibilities • process applications • assign IRDI values • maintain a Data Element Registry • Assign appropriate Registration Status • Submit DE for registration • Provide supplemental info • Specify DE • Arbitrate • semantics • name • domain • Reconcile • Clarify • Advise • Notify • Resolveconflict • Consult • Notify SOs of its decisions Submitting Orgnaization Responsible Orgnaization Registration Authority

  12. Responsibilities of Submitting Organizations (SO) • Provide the information specified in Annex A in the form required by the RA. • Provide any additional information that may reasonably be required by the RA to enable it to perform its responsibilities. • Ensure that when a data element has been registered, specification of the attribute values of the data element is not changed without first advising the RA.

  13. Responsibilities of Responsible Organizations (RO) • At the RA's request, advise on the semantics, name, and permissible value of data elements submitted for registration. • Notify the RA of any amendments to the data elements assigned to the RO. • Decide, in case of confusion and/or conflict, on the attribute values of the assigned data elements.

  14. Responsibilities of Registration Authorities (RA) • Receive and process applications for the registration of data elements, assign IRDI values, and maintain a Data Element Register in accordance with the following provisions. • Consult the appropriate ROs when requests affect the mandatory attributes of the data elements being registered. • Handle all aspects of the registration process in accordance with good business practice and, in particular, take all reasonable precautions to safeguard the Register. Specifically, the responsibilities of an RA are as follows: • Receive applications for the registration of data elements from its SOs. • Review and facilitate the progression of the applications through the registration cycle. • Assign appropriate Registration Status. • Notify SOs of its decisions according to the procedure of this standard.

  22. Registration Authority Identifier (RAI) * Data Identifier (DI) Version Identifier (VI) Structure of International Registration Data Identifier (IRDI) Organization Part Identifier (OPI) OPI Source (OPIS) ** International Code Desiginator (ICD) Organization Identifier ** Optional * Same as ISO 6523 Notes: IRDI is an internationally unique Identifier

  23. Rules for Identification of Data Elements • Each data element shall be unique within a registration authority • The combination of identifier, registration authority (and version) shall make a unique identification for a data element • To be assigned an identifier, a data element shall satisfy all conditions specified in all parts of the standard

  24. Retired Standardized Certified Recorded Incomplete Registration Status

  27. So You want to become a Registration Authority ?

  28. Steps to establish a Registration Authority (RA) • Secure an RA Identifier (RAI). • Prescribe, amend, and interpret the procedures • Determine any additional conditions specifically required by its domain of registration. • Specify the format for each attribute listed in Annex A of ISO/IEC 11179-6 and for any additional attributes. • Determine the format and media in which applications shall be submitted.

  30. Are these standards being used ? • Reference Implementation: • US EPA’s Environmental Data Registry (EDR): www.epa.gov/edr. Presentation follows. • Australian Institute of Health and Welfare’s National Health Information Knowledgebase (NIHK): www.aihw.gov.au/nhik/index.html. • In Progress: • Learning Object Metadata Group (LMOG): http://jetta.ncsl.nist.gov/metadata/ • Census Bureau’s data registry. • Adoption: • ISO TC 204, Transportation, resolved to use ISO/IEC 11179 as the standard for data dictionories. • The United Nations’s Basic Semantic Repository Project utilizes much of ISO/IEC 11179 as its foundation.

  31. For Your Information • NCITS/L8 is Committee for Data Representation under ANSI. It is also the US Technical Advisory Group to ISO/IEC/JTC1/SC 14. • Phone: +01 703 908 2433 Fax: +01 703 908 2412 • email:ngo.phongx@cpmx.saic.com • FTP for NCITS/L8 and SC14 is scdt-sunsrv1.nscl.nist.gov Directory X3L8.
