Very glad to see ISO/TC 211 friends again!

Warmly welcome all of you to China!

Happy and Welcome

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 MOD GB/T 19710-2005

ISO 19113:2002 IDT FDIS

ISO 19114:2003 MOD FDIS

ISO 19108:2002 IDT WD

ISO 19110:2005 IDT Underworking

……

Adopt or adapt ISO 19100 standards

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

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

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.

Researching on the Metadata Standard for Geographic data

Published a Book to collect the results from such researching work in 1999

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

Publish a Guide Book of International Standards for Geographic Information

It includes a Part of drafts of ISO 19100 Standard Series

The Contents of

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 )

…

Using National Standards replace International Ones

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

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

2005-10 in Hangzhou, Zeijiang Province

2007-08 in Yantai, Shangdong Province

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.

ICA Book: World Spatial Metadata Standards

It is edited by Professor Moellering

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

…

Example of the Profile from GB/T 19710:2005

Metadata input system of the PRC-GEF Partership on Land Degradation in Dryland Ecosystems

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

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

The metadata results of retrieval

Open one of the retrieved metadata results

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

Many Thanks !
