  2. Contents • Introduction • Overview of Metadata Standardization in Korea • Brief History of MDR Standardization • Organizations for Standardization • Key Agents for MDR Study • MDR Standards in Korea • MDR Projects in Korea • MDR for Industrial Information(KATS/KISTI) • Metadata Crosswalk for Bibliographic Information(KDPC) • Perspective

  3. Introduction • Several projects were performed in Korea in the past ten years to implement metadata registries based on ISO/IEC 11179 standard. • A couple of experimental studies were performed to show what ISO/IEC 11179 MDR means in some domains during the early stage. • After that, a project were performed to implement an MDR in industrial domain using top-down approach. • Recently, another project has been performed using bottom-up approach in bibliographic domain. • In this session I will review metadata standardization activities and projects performed in Korea and look out over standardizing and implementing MDR in Korea.

  11. Revitalization of Industrial Information Service Information Service Based on DOI MDR System Data Quality National Industrial Information Standardization Project MDR for Industrial Information(KATS/KISTI) Overview of the Project • Standardization of Metadata for Industrial Information • Implementation of Industrial Metadata Registry • Developing a prototype of Standard Information Service by Identifier

  13. MDR for Industrial Information(KATS/KISTI) Overview of the IMR System (1) • Organizational Structure • KATS provided fund. • KISTI planed and operate the project. • Yonsei University developed the IMR. • Period of Development : two years • Structure of IMR • Administration Function • A Group of sub-MDRs • Sub-MDRs can be automatically created through the Administration Function • Automatic Script Generator for metadata users • DB script(Oracle, mySQL, MsSql, Sybase…) • Text • XML

  14. MDR for Industrial Information(KATS/KISTI) Overview of the IMR System (2) • Registration Items : Nine Administered Items • Data Element, Data Element Concept, Conceptual Domain, Value Domain, Object Class, Property, Representation, Classification, Permissible Value, Value Meaning • Retrieval by Domain, Type, Status • Retrieval and Input of XML Tags • Linking Related Items

  21. Metadata Crosswalk for Bibliographic Information (1) • Many attempts have been performed to make metadata crosswalks: • LC, OCLC, Getty, UKOLN, IEEE, … • Simple crosswalks are not enough. • Semantic metadata mapping is required. • ISO/IEC 11179 standard provides good provisions for metadata semantics. • Crosswalks can be properly used only when a specific domain is involved.

  22. Metadata Crosswalk for Bibliographic Information (2) Semantic Metadata Mapping Process • To set up a process for making metadata crosswalks conform to ISO/IEC 11179 standard. • Semantic metadata mapping (SMM) process ISO/IEC 11179 MDR (N:1) DEC CD (1:N) (1:N) (N:1) DE VD MARC GILS DC ONIX … Crosswalk

  23. Metadata Crosswalk for Bibliographic Information (3) Overall Process 1st Collecting metadata schema 2nd Grouping attributes 3rd Finding common DECs 4th Mapping into a table • The 2nd and 3rd steps can be replaced by each other. • The process is applicable to a specific domain only.

  24. Metadata Crosswalk for Bibliographic Information (4) Application to e-Book • Domain: e-Book • (1st) Available metadata sets: OpenEBPS, MODS and TEI • primary metadata set: OpenEBPS

  25. Metadata Crosswalk for Bibliographic Information (5) Application to e-Book • (2nd) Grouping attributes

  26. Metadata Crosswalk for Bibliographic Information (6) Application to e-Book • (3rd) Constructing common DECs based on 11179: • Object class: e-Book • Properties: title, author, subject, abstract, publisher, distributor, authority, contributor, publication-date, genre, format, extent, identifier, language, coverage-geographic, coverage-temporal, right, location, edition • DECs: ebookTitle, ebookAuthor, ebookSubject, ebookAbstract, ebookPublisher, ebookDistributor, ebookAuthority, ebookContributor, ebookPublication-date, ebookGenre, ebookFormat, ebookExtent, ebookIdentifier, ebookLanguage, ebookCoverage-geographic, ebookCoverage-temporal, ebookRight, ebookLocation, ebookEdition

  27. Metadata Crosswalk for Bibliographic Information (7) Application to e-Book • (4th) Mapping into a table

  28. Metadata Crosswalk for Bibliographic Information (8) Summary and Future Work • A Semantic Metadata Mapping (SMM) process to make metadata crosswalks was established. • Types of metadata mapping were suggested to show how to harmonize between correspondent attributes. • Crosswalks among OpenEBPS, MODS and TEI headers were obtained to apply to e-Book. • The SMM process will be elaborated in order to be proposed as a new work item in ISO/IEC JTC1/SC32 this year.

  29. National Metadata Center Perspective • Two Main Measures for Implementing Active MDR • Training metadata people • Too small number of standard engineer • Institutionalize to enforce use of MDR • Development without application is useless Library MDR Educational MDR Scientific MDR Cultural MDR Industrial MDR *** MDR
