Major Objectives and Scope
The aim of the cooperation is to promote and establish a researchcommunity to build the infrastructures to solve the global data issues.
1. ActivitiesThe primary activities are agreed as follows:- Exchange of information including data
- Exchange of researchers- Promotion of cooperative projects in a common field of interesto×oo

2. Cooperation field
The cooperation will focus on the following studies, and personnel of theother field of interest by either institute may be invited to participate in
the joint work independently from other institutions with mutualagreement.
- Make global geophysical data accessible for other science domains
×- Make network of global observation data for integrated approach witho×the same metadata vocabulary
o×- Enhance usage of the common observational infrastructure- Promote cooperation in the area of studies on solar, heliospherical, solarterrestrial and geophysical activity
o- Use the e-infrastructures for education and for capacity buildingoCooperation among data systems
Future direction: To establish a close collaboration among
various data systems

Open Semantic Framework (OSF)
Frédérick Giasson
Web-oriented architecture• Data is generally exposed/open anduniversally available as linked data
• SPARQL endpoints and APIs aregenerally RESTful in design• The overall architecture is modular,
with inherent decentralized anddistributed aspects• All display and visualization aspects
are cross-browser ready and capable.

Mashup of IUGONET, ESPAS and ISDC data server
Mapping of terminological ontologies• IUGONET: SPASE, GCMD science keywords• ESPAS: ESPAS ontology• ISDC: GCMD keywords, SPASE, GEMET
and/or mapping of domain models using DCAT domain ontology
Proof of concept (keyword based mashed-up catalog queries):• Open Semantic Framework for application• Ontology based (mashup of particular catalog entities)• IUGONET API: DSpace OpenSearch Query• ESPAS API: under construction• ISDC API: SPARQL• Integration of context data via LOD: SPARQL

Planed Actions
Creation of a Semantic Knowledge Network• WDS is establishing a Knowledge Network (KN) for scientificmetadata (similar to Web of Science)*
Whether looking at data, books, journals, proceedings or patents,
Web of Science provides a single destination to access the most reliable,
integrated, multidisciplinary research. Quality, curated content delivered
alongside information on emerging trends, subject specific content andanalysis tools make it easy for students, faculty, researchers, analysts,
and program managers to pinpoint the most relevant research to informtheir work.
• KN implementation working group in WDS– D2RQ Framework (e.g. using GFZ/FHP experiances)– Mashup of semantic/vocabulary resources (e.g. IUGONET, ESPAS, ISDC)– ...

ResearchResearch Data Management with Semantic Web Technology• Collaboration in education and project based research since 2010
• Education and research in information science => data scientist• Current topics: 4 work packages

Future Developments and Capabilities – Internet of Things• Big player activities (Google, Microsoft, Apple, Amazon, ..)− Big Data: collecting more and more data (“Datenkrake”)− Smart data: mashing-up Big Data (e.g. social networks)− Smart services: maps & navigation, education, … (e.g.
Google Maps/Earth, Scholars, ..)Artificial

Call for design of scientific vocabularies
CAWSES-II Nagoya 2013, AGU/EGU/JpGU/AOGS 2013/2014/2015

Please help to create a well agreed keyword vocabulary
for space weather and climate including neighbor disciplines
such as e.g. earth magnetic field or solar-terrestrial physics.
• Report the keyword vocabulary you are using• Find common agreement in the use => standard• Discuss and agree about concordances and mashups in your own domain and cross-domain

Please contact IUGONET or ESPAS:
