1. The GEOSS Data Sharing Principles and Guidelines for Implementation GEOSS Data Providers Side Event St Petersburg – 7th November Dr. Michel SCHOUPPE European Commission DSWG co-chair

2. Data Sharing: the backbone of GEO
Fundamental enabler to address global societal challenges
One of GEO’s significant achievements
Prerequisite for building a stronger GEOSS
Requires further advocacy of data sharing implementation and the articulation of evidence
"The success of GEOSS will depend on a commitment by all GEO partners to work together to ensure timely, global and open access to data and products” (Cape Town Ministerial Summit, 2007).

3. GEO in a changing global data landscape
Rising open data trend worldwide Few examples:
2013: G8 Open Data Charter
2014: Copernicus open data policy
2015: International Open Data Charter Belmont Forum policy on open access to research data and e-Infrastructures
2016: ICSU call for international accord on Open Data in a Big Data World
Rise of digital networks, e-Infrastructures, use of big data 3

4. Milestones related to the GEOSS Data Principles
2005: 10-Year Implementation Plan ( ) st version of the GEOSS Data Sharing Principles
2009: GEOSS Data Sharing Implementation Guidelines
2010: GEOSS Data Sharing Action Plan "GEOSS Data-Core" concept
2015: Mexico City Declaration - GEO Strategic Plan ( ) Revised version of the GEOSS Data Sharing Principles (DSPs)
- GEOSS Data Management Principles (DMPs) and Guidelines
2016: Updated Implementation Guidelines for DSPs and DMPs

5. Revised GEOSS Data Sharing Principles 2010-2025
Data, metadata and products will be shared as Open Data by default, by making them available as part of the GEOSS Data Collection of Open Resources for Everyone (Data-CORE) without charge or restrictions on reuse, subject to the conditions of registration and attribution when the data are reused
Where international instruments, national policies or legislation preclude the sharing of data as Open Data, data should be made available with minimal restrictions on use and at no more than the cost of reproduction and distribution
All shared data, products and metadata will be made available with minimum time delay.
See slide text 5

6. New features of the GEOSS Data Sharing Principles
Sharing EO as open data by default = the GEOSS norm
Sharing with restrictions : perceived as an exception
Alignment with the G8 Open Data Charter
Refrains from imposing charges that exceed the cost of reproduction and distribution
For any purpose by anyone
Sharing EO data as part of the GEOSS data-CORE
Call by GEO to make, to the largest extent possible, Earth observation data available and accessible through the GEOSS
GEOSS Data-CORE as the advocated GEOSS mechanism
Removal of some ambiguities, language clarification 6

8. Two-phase registration of new GEOSS data sets
Administrative registration (for the GEOSS registry): information such as the data sets Provider's name, its eventual GEO affiliation, points of contact, data category and type, data policy and data accessibility applied by the Provider.
Technical registration (for GEOSS brokering): information such as the Web service(s) or Web API(s) by the Provider's system, the metadata re-harvesting time, the account to be used to access the data set
Main contact point:

9. Tagging data as GEOSS Data-CORE
When ? In the case a data set is shared as Open Data by default
What? Expressed as special character strings (tags) and placed in the metadata. Availability of four metadata tags that describe the data in the GEOSS Data-CORE:
geossDataCore (GEOSS Data-CORE belonging)
geossNoMonetaryCharge (availability at no cost)
geossUserRegistration (user registration needed)
geossAttribution (attribution required)
How? Main contact point:

10. Legal interoperability of GEOSS Data-CORE data
Best approach: legislative waiver of rights and placing in the public domain
Alternatively, waivers and common-use licenses can be adopted on a voluntary basis (e.g. PDM, statutory waiver of copyright, CC0, PDDL,CC BY 4.0).
Custom licenses or waivers must be:
Compatible with the GEOSS Data-CORE:
Valid under the laws of as many different jurisdictions as possible
Clear and understandable to the user
Easy to find and recognize
Embeddable in the data as machine readable metadata
Available in different languages

11. Other underpinning data aspects are covered by the GEOSS Data Management Principles

12. In conclusion: Data Sharing remains a fundamental GEO activity
Continued need to:
Promote open data sharing, the GEOSS Data-CORE and expansion of national coordination mechanisms
Monitor data policy "readiness" and GEOSS data availability and usability
Analyse impact / benefits (e.g. SDGs and SBAs)
Report on GEOSS data sharing
Refine implementation guidelines
Explore data sharing implications from new observing systems
Data sharing
