GEOSS Data-CORE: State-of-play
•
GEOSS Data-CORE: the GEOSS Data Collection of Open Resources for Everyone
is a distributed pool of documented datasets with full, open and unrestricted access
at no more than the cost of reproduction and distribution.
• Data-CORE is a subset of all data registered in the GEOSS
•
The establishment of the GEOSS Data-CORE was approved at the GEO Summit
in Beijing in 2010 and started in 2011. Progress was slow in 2011 and 2012 but has
accelerated since 2013.
•
Four GEOSS Data-CORE tags for use by the data providers:
1. geossDataCore
(basic tag, identifies the data as GEOSS DataCORE)
2. geossNoMonetaryCharge (data available at no cost at all)
3. geossUserRegistration (user registration required)
4. geossAttribution
(data citation required)
 Guideline document prepared by the DSWG: "Instructions for GEOSS Data
Providers: How to place tags in the Metadata for GEOSS Data-CORE"

GEOSS Data-CORE: State-of-play (continued)
•
Since October 2012, GEO Members and Participating Organisations that had
pledged resources to the GEOSS Data-CORE have been contacted to make their
open resources visible and available as such.
•
GEOSS Data-CORE resources are identified on the GEOSS Web Portal
(http://www.geoportal.org/ ) thanks to the GEOSS Data-CORE icon:
•
A ranking mechanism allows GEOSS Data-CORE datasets to appear at the top of
the list of results returned after a query.
•
It is important to ensure that appropriate working links to access the data are
provided with the metadata.

GEOSS Data-CORE: State-of-play (continued)
•
•
The GEOSS data CORE concept has the potential to be one of the key success
stories of GEOSS, distinguishing it from any other web-based infrastructure.
Further effort is needed to increase awareness/use of the GEOSS Data-CORE
– Too many members of the GEOSS community of users
are not yet aware of / not yet using available GEOSS Data-CORE datasets;
– Some thematic areas still poorly represented amongst the GEOSS Data-CORE;
– Spatial extent and temporal resolution of available GEOSS Data-Core datasets
often do not fit users’ needs;
– Need to collect usage metrics for GEOSS Data-CORE
 On-line survey 2013 to assess the level of awareness about the GEOSS
Data-CORE, understand the community willingness to contribute to it and use
it, and identify potential barriers preventing its use.
 New survey 2014 in preparation by the FP7 GEOWOW project (www.geowow.eu)
 Definition of use metrics in AIP-6 to be collected and reported in the key apps
developed in AIP-7

Task
GEOSS Data-CORE: State-of-play (continued)
•
Need to keep expanding the GEOSS Data-CORE datasets
– Check the list of GEOSS Data-CORE pledges, contact relevant data providers;
solicit new pledges…
•
Need to systematically monitor and maintain the available GEOSS Data-CORE
– Use of agreed demonstrated metrics, check of duplicate records, assess and report
on real accessibility and effective use of the GEOSS resources;
•
Need to provide “first aid” assistance to GEOSS Data-CORE providers and users
– Reference point of contact at the GEO Secretariat;
– Need for updated, maintained, simple registration Guidelines for Data Providers
and manuals for GEOSS users
Need for further coordination amongst the GEO contributors and their activities:
– Including the DSWG, the IIB, the future Data Management Task Force, task IN-01
“Earth Observing System”, task IN-02 “Earth Data Sets”, task IN-03 “GEOSS
Common Infrastructure”, the Standards and Interoperability Forum and the AIPs

Other contributions by the DSWG
of relevance to data sharing and management
 DSWG Summary white paper on “Legal options for the exchange of data
through the GEOSS Data-CORE” (2012)
 This paper provides insight on what legal interoperability of data means, promotes the
use and provides examples of standard waivers or common-use licenses that meet
GEOSS Data-CORE conditions of access.
 DSWG Guidelines “GEOSS Data Quality Guidelines” (2013)
 This paper outlines data (quality and characteristics) documentation issues, including
core metadata and quality tags for fitness-for-purpose for consideration by data
providers. It also calls for standardised mechanisms to allow data users to provide
feedback on usability to data providers and other data users.
 Short review paper prepared by the DSWG Sub-Group on Legal
interoperability: “Interpretation of the full and open access to and use of
(geographic) data: existing approaches” (2013).
 This paper focuses on the comparison of the terms used as equivalents to ‘full and
open’ concept for sharing data through GEOSS, and highlights the similarities and
differences in the approaches, policies and their implementation in various jurisdictions.

Other contributions by the DSWG (sub-)groups
of relevance to data sharing and management (cont.)
 DSWG proposal for revised GEOSS Data Sharing Principles:
“GEOSS Data Sharing Principles post 2015” (March 2014)
 This paper considers the changing international landscape for data sharing
over the past years, in particular the accelerating trend towards open data, to
revisit the 2005 GEOSS Data Sharing Principles. The aim of updating the
principles is not only to clarify and improve the language, but more
importantly to ensure that they advance GEO’s vision and objectives and that
GEO continues to play a key role in accelerating the global trend towards
truly open data sharing in support of society.
 For submission/review in 2014 by IPWG, EXCOM and Plenary
