Introduction
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.

Brief history of mdr standardization
Brief History of MDR Standardization

  • In 1990s

    • Proposal for data standardization

    • Standards: codes, data interchange

  • In 2000s

    • Performed several projects to construct MDR prototypes

    • Standards: data elements, MDR

  • In 2010s

    • Expect to implement active MDRs.

Metadata crosswalk for bibliographic information 1
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.

Semantic Metadata Mapping Process

  • To set up a process for making metadata crosswalks conform to ISO/IEC 11179 standard.

    • Semantic metadata mapping (SMM) process

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.

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

  • (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

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.

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
