  1. METADATA STANDARDIZATION ACTIVITIES IN CHINA JIANG JINGTONG National Geomatics Center of China 2007-10-31 XI’AN

  2. Happy and Welcome • Very glad to see ISO/TC 211 friends again! • Warmly welcome all of you to China!

  3. Adopt or adapt ISO 19100 standards In recent years, we worked on transforming some ISO 19100 standards into Chinese national standards: ISO 19105:2000 IDT GB/T 19333.5-2003 ISO 19115:2003 MODGB/T 19710-2005 ISO 19113:2002 IDT FDIS ISO 19114:2003 MOD FDIS ISO 19108:2002 IDT WD ISO 19110:2005 IDT Underworking ……

  4. Metadata Term in Chinese and Definition • Different translations for the term METADATA into Chinese such as descriptive data（描述数据）, explanative data（诠释数据）, meta data（元数据）, etc. • Similar definition for METADATA as ISO/TC 211

  5. Learn from CSDGM • FGDC metadata standard, Content Standard for Digital Geospatial Metadata (CSDGM) to be introduced into China before ISO 19115 • Discussed FGDC metadata standard with experts of FGDC at the USGS early 1990s • Using CSDGM as a basis for working-out metadata standard in some industries in China

  6. Research on Metadata • Some topics for researching on metadata have been carried out, such as metadata definition, related terms, metadata contents, layers, collection, issue, retrieval, quality control, and so on. • At the same time, metadata standardization is one of the key subjects.

  7. Researching on the Metadata Standard for Geographic data Published a Book to collect the results from such researching work in 1999

  8. Attend the development of the ISO 19115 • Learn more things about metadata standard • Attend discussions during the standard developed • Bring forward comments for the standard • Invite Mr. Danko visit China giving us lecture • Hold training class for UML for better understanding the standard

  9. Publish a Guide Book of International Standards for Geographic Information It includes a Part of drafts of ISO 19100 Standard Series

  10. The Contents of the Guide Book

  11. Working-out the National Standard Adapted from the ISO 19115:2003 GB/T 19710-2005 ISO 19115:2003, MOD

  12. Working-out the National Standard Adapted from the ISO 19115:2003 • Main modified • Add some terms and definitions • Simplify some sections and entities • Use National Standards replace International Ones • Add a New Annex K ( informative ) • …

  13. Using National Standards replace International Ones

  14. Add a New Annex K ( informative ) • Including 9 sections, 38 entities and 104 elements • Extent some elements for image data • Add two codelists: MD_GeodeticDatumCode • MD_ HeightDatumCode • Add four instances • In fact, it is a profile of the standard

  15. Hold two training classes for Understanding the National Standard • 2005-10-19~21 in Hangzhou, Zeijiang Province • 2007-08 in Yantai, Shangdong Province • People from different provinces and different industries attended the classes • JIANG Jingtong, LIU Ruomei, ZHOU Xu and JIANG Yunpeng give lectures

  16. 2005-10 in Hangzhou, Zeijiang Province

  17. 2007-08 in Yantai, Shangdong Province

  18. Develop software tools for Implementing the Standard • The software tools for metadata input and issue have been developed. • The software tools are published on several websites to let people download freely.

  22. ICA Book: World Spatial Metadata Standards It is edited by Professor Moellering

  23. Create Community Profiles from the National Standard GB/T 19710:2005 • The Profile in the Ministry of Land and Resources • The Profile in the Ministry of Water Resources • The Profile for Sharing Data of Sustainable Development in China • The Profile for PRE-GEF Partership on Land Degradation in Dryland Ecosystems • …

  24. Example of the Profile from GB/T 19710:2005 Metadata input system of the PRC-GEF Partership on Land Degradation in Dryland Ecosystems

  25. Metadata input of the PRC-GEF Partership on Land Degradation in Dryland Ecosystems element by element

  26. Metadata management and retrieval system of the PRC-GEF Partership on Land Degradation in Dryland Ecosystems

  27. The metadata results of retrieval

  28. Open one of the retrieved metadata results

  29. What’s in future? • More training classes for understanding the national metadata standard • Develop software tools for input and issue metadata • Establish more Community Profiles from the National Standard GB/T 19710:2005 • Translate metadata which was collected by the standard based on FGDC CSDGM • Transform more ISO 19100 standards such as ISO 19115-2、ISO 19138 and so on

  30. Many Thanks !
