Group Introduction

Group missions

To provide access to efficient digital interoperable cross disciplinary geoscience standards, knowledge systems, tools and methodologies in convenient forms for DDE geosciences data for science, public and industry, for better insights into the distribution and value of earth’s resources and materials.

(1) Review of DDE semantic knowledge system

(2) DDE standards architecture and coordination of portfolio of standards necessary to implement DDE ten-year plan

(3) Training and evaluation on existing relevant standards and newly issued standards for implementation in DDE

(4) Geoscience Data Exchange Standards

(5) Earth Resource Data Exchange Standards

 

three-year goals (2020-2022)

(1) To completed the review of the DDE Knowledge System, including science content and platform functionality, and to provide an authorized approval report for a better release of DDE’s geosciences knowledge deliverable product version 1.0 which will equally benefit schools/universities, organizations and individuals with geoscience knowledge.

(2) To provide efficient data standards as solid pillars supporting DDE’s mission of harmonizing global Deep-time Digital Earth data, and sharing global geosciences knowledge, including in-depth training to DDE working groups on existing relevant standards and implementation methodologies, and issuing DDE Metadata standrads for data Findable.

(3) To support the DDE Big Science Program of laying a solid basement with fundamental key data standards and necessary digital tools which enable efficient access to distributed multi-disciplinary geoscience databases, knowledge systems and linked DDE centers of excellence for data Accessible,

Interoperable and Reusable that helps DDE to transform Earth science.

 

 

Project Description

1. Brief description

The IUGS 10-year Big Science Program Deep-time Digital Earth (DDE) involves vast geoscience domains and participation of various geosciences organizations such as universities, research institutes, geological surveys, laboratories and data centers. Data sharing and exchange among globally distributed multi-disciplinary heterogeneous databases for geoscience discovery is the only way for DDE to its goals. A harmonized and powerful geosciences data standard system is essential and critical for the implementation of DDE. However, such a standard system has not yet been established at global scale, including unified geoscience vocabulary, geoscience disciplinary classification and resources description, data integration, processing, analysis, and release.

Goal of DDE Standards Task Group (DDE-STG) is to set up such a geosciences data standard architecture and to develop data standards accordingly on efficient digital interoperable cross disciplinary geoscience databases, standards, knowledge systems, tools and methodologies in convenient forms for DDE geoscience discoveries for science, public and industries on better insights into the distribution and value of earth’s resources and materials.

This annual proposal is to take the first steps towards the review of DDE semantic knowledge system, providing training to the DDE working groups on existing relevant standards and implementation, and getting on the way to develop metadata standards and geoscience data exchange standards based on world-wide implemented CGI/OGC and ISO standards to implement DDE.

For a successful conduction of annual activities and obtain relevant achievements, budget support from DDE to the DDE-STG is necessary and critical.

2. Expound on the alignment with the vision and mission of DDE

The annual proposal is closely aligned with the vision and mission of the DDE, and of the role of DDE-STG within the overall DDE framework. The annual work will organize and complete the review of DDE knowledge graph/system and provide an authorized approval report to DDE Science Committee/Executive Committee (SC/EC) on a better knowledge graph/system in data-driven deep-time discovery of the Earth with machine.

The annual work of DDE-STG will also provide training on relevant world-wide implemented geosciences data standards and advices to implement DDE towards the FAIR principles and Open Services.

Further major annual activities include organizing meetings focus on DDE standards technology and work plan for data driven discoveries, and organizing global working teams within and out of DDE on issuing practical standard system architecture, a metadata standard and data standards for all the DDE Working Groups (WGs) and other DDE Task Groups (TGs) on efficient web-based data Finable, Accessible and Interoperable cross multiple disciplinary geoscience databases, knowledge systems, tools and methodologies.

3. Milestones and timeline

Aim of the annual plan of DDE-STG proposed herewith is to conduct the first step work towards creating DDE standards system and geoscience data standards, including DDE knowledge system review, DDE metadata standard and training courses to meet urgent needs form DDE Big Data Group, Knowledge Group, Platform, and DDE working groups (WGs) and other task groups(TGs).

Milestones of the outcomes of the proposal include, but is not limited to:

(1) DDE knowledge system review report

DDE-STG will guide the science contents review and functionality review of the DDE knowledge system, so as for DDE to release the first products in time. And an authorized review report will be submit to DDE SC/EC.

The science contents review procedure is already drafted, so far.

(2) Standards training courses

DDE-STG will organize training courses to meet the demands of DDE on relevant existing world-wide implemented geoscience data standards and metadata standards for DDE WGs and other TGs in 2020, whenever the project budget allow.

Advices on implementation of these standards will provided and a survey conduct on DDE data standards architecture.

(3) DDE metadata standard (draft version)

DDE-STG will study and issue the metadata standards on existing world-wide implemented ISO metadata standards and web application technologies to well meet the demands form DDE on dataset and data services sharing and discovery (Finable), whenever the project budget and resource allow.

The DDE metadata standard will be drafted in 2020 for urgent use based on ISO 19115-1 (2014, discovery and service metadata profiles), and upgraded later on.

(4) Working Teams for DDE geosciences data standards

DDE-STG will organize a global standards working teams form CGI-IUGS, CODATA, OGC, and DDE WGs for multi-disciplinary geosciences data exchange and Earth resources and materials data exchange aiming at efficient DDE geosciences data Accessible and Interoperable based on world-wide implemented CGI/OGC GeoSciML and EarthResourceML.

 

Timeline of the annual proposal:

Phase One - 1 January/April to 30 September: Focus on DDE knowledge system review.

• DDE-STG Face to Face meeting and work plan discussion
• DDE knowledge system review guide and review procedure towards DDE’s release of product version 1.0 in late 2020.
• Standards training courses preparation and start to conduct.
• DDE metadata standard draft started.

       Phase Two -1 October to 31 December: Focus on DDE metadata standard.

• DDE knowledge system review report to DDE SC/EC for the product release.
• Standards training courses summary for DDE standard architecture and a plan for DDE data exchange standards development.
• DDE metadata standard v.2020 provided for use.

       Phase Three -1 January2021 to 30March 2021: Focus on DDE data standards working team

• DDE standard architecture draft and portfolio.  
• Setting up the working teams to carry out DDE data exchange standards development plan.
• DDE-STG work plan of 2021 and a draft five year plan.

 

4. Feasibility analysis

DDE-STG leader and member scientists come from CGI, the committee for geoscience information of IUGS, CODATA, OGC and geoscience standards and technology related international and regional organizations with rich experiences in both international geoscience data standards development and world-wide implementation. The proposal annual plan of DDE-STG is also in kind cooperation with international organizations, universities and national geological surveys. And the proposed plan of knowledge graph review, standards training, metadata and data exchange standards etc. can be conducted and completed in time on the bases of existing international well-implemented standards and work forces, whenever the budget allow.

Thus, this proposed annual plan of DDE-STG can be implemented in time in success with proper budget support.
