National Institute of Information and Communications Technology

JpGU has been facilitating sessions related to data and information topics in past meetings, convened by groups/communities
with interdisciplinary interests including informatics, scientific data management, data systems, databases, and social network
services. This session will be a forum of those topics of papers, encouraging exchanges between those groups and communities. New dimensions and cross-disciplinary subjects are expected for further contribution to advancing the earth and planetarysciences. On the other hand, Open Data and Open Science are increasingly becoming hot topics, in parallel to establishing
ICSU-WDS (2008), G8 Open Data Charter (2013), deployment of RDA (2013), and so forth, in addition to development of Open
Access of journal articles. The JpGU community will be encouraged to discuss about our reaction, our contribution to the above
data and information issues, and what future benefits and problems inherent in earth and planetary sciences will be.

The Integrated Ocean Drilling Program ran from Oct. 2003 through Sep. 2013 and is now succeeded by the International
Ocean Discovery Program from Oct. 2013. The scheme for international scientific ocean drilling has be in place since about
half a century ago. The data policy of IODP has been in development over the years. This talk will touch on the IODP datacollection, distribution, archiving system. All nations participating in IODP are required to agree on principles of scientific ocean
drilling including the data policy. In IODP, data producers and data users overlap and co-exist (adopting moratorium period is
one mechanism for its support). It requires good data management with the recognition that the data samples are the legacy of the
program. An important point is that all discussion on data policy worked bottom up from the science community before acceptedby the funding agencies.

Research Institute for Humanity and Nature

The Research Institute for Humanity and Nature (RIHN) was founded in 2001. It is part of the National Institutes for the
Humanities, a Japanese inter-university research institute corporations. RIHN’s mission is to conduct integrative and cooperative
research that examines and clarifies the interactions between human and biophysical systems, to identify the key aspects and processes of environmental change and to suggest how harmonious human-environmental relations can be established or enhanced(see http://www.chikyu.ac.jp/rihn e/goals.html). The RIHN solicits, develops, funds, and hosts fixed-term research projects incollaboration with researchers affiliated with universities and institutes, as well as diverse stakeholders. Most researchers employed by RIHN are not tenured, and tend to leave the institute within a few years. Given the absence of an explicit policy
regarding research outcomes, this high academic fluidity has disturbed the accumulation and utilization of research outcomes at
the institute.
To address this structural problem, the RIHN established a data policy in 2014. The policy respects the rights of the individuals
and groups who create research outcomes as much as possible. Under this principle, the RIHN will not inhibit the execution ofcontracts required for creating outcomes. Moreover, the RIHN will not prevent individuals and groups from utilizing or giving
to third parties the research outcomes they created. These rules are designed to avoid conflicts with the data policies of otherinstitutions as much as possible. Respecting rights of researchers is expected to facilitate the accumulation and utilization ofresearch outcomes.

In the National Institute of Polar Research, perform the integration and sharing of data across a multi-disciplinary such asatmosphere, ocean, snow and ice, land, ecosystem, model, for the purpose of cooperation and integration across disciplines, webuild the Arctic Data archive System (ADS). ADS to promote the mutual use of the data across a multi-disciplinary to collectand share data sets, such as observational data, satellite data, and numerical experiment data. Through these data sets, clarifyof actual conditions and processes of climate change on the Arctic region, and further contribute to assessment of the impact of
global warming in the Arctic environmental change, to improve the future prediction accuracy. Currently, researchers have been
uploaded various data. To promote the data registered by researchers, it is necessary to provide the benefits for researchers.
Now, Japan Link Center (JaLC) performs the investigation of DOI mechanisms of research data, even in Japan has enabled
DOI given to research data. DOI is a digital object identifier, and is an identifier given permanent link to a document, etc. on
the Internet. It makes possible for researchers to cite the data used in a scientific publication, which is called ”data citation”.
DOI of research data for researchers to use, not only the citation data to scientific papers is simplified, and also by obtaining themetadata, search of data is become easily. On the other hand, data contributors become possible to be right evaluated and rewards
for their published data in the same way as for scientific publications. However, the DOI registration to JaLC is just structure,and can be technically given about any kind of data without quality. The responsibility for the data quality and long term storage
and keeping permanent link of data is in the DOI publisher side. National Institute of Polar research started discussion to giving
DOI to scientific data. In this presentation, we will presentation the discussion situation.

3Open Data and Open Science are initiatives which provide a framework and rules for openly shared governmental and scientificknowledge. This paper describes our efforts and latest experiments to mashup heterogeneous geo and space science data systems
and servers according to Open Data and Open Science concepts based on the semantic web approach. The main focus here ison the mashup of data server designed, implemented and run by three different e(i)-science infrastructure projects, which are theJapanese inter-university IUGONET metadata database, the European Union funded ESPAS platform and the GFZ prototype ofa semantic web based ISDC data portal. The intersection of the scientific domains of the projects and related data is the nearearth-space area including in-situ and remote geomagnetism observations. The appropriate data systems and servers based on
different e-infrastructure solutions are not interoperable. To overcome this disadvantage the design of an interoperable layer upon
the used infrastructure based on- merged domain and terminological models (ontologies)- transformations of resources into RDF structures, and- the mashup of linked data resources
has been done in cooperation with the information science department of the university of applied sciences Potsdam. This
paper also shows the latest results of our experiments integrating D2R server and services for the mashup of relational databasestored resources and the use of the Open Semantic Framework (OSF) for the enhancement of the semantic web based GFZ ISDC
prototype.

In the present paper, we introduce a repository system for upper atmosphere and space science that has functions of data
disclosure and flexible authentication.
WEKO is an open source software for repository system developed by National Institute of Informatics (NII). WEKO works
on the NetCommons2 (NC2), which is a Content Management System (CMS), and is used for JAIRO Cloud and institutional
repositories of academic communities and universities. In addition, WEKO is able to provide specific metadata format such as
Dublin Core, Junii2 using the harvesting protocol OAI-PMH.
It is not sufficient to introduce WEKO by default for a data repository of upper atmosphere and space physics. For example, thedefault metadata formats are not appropriate for observation data in the field of upper atmosphere nor space science. Secondly,
it is necessary to customize the functions implemented in WEKO for our use case. So we added some additional functions toimprove WEKO, and we constructed a repository site for Akebono VLF Data[1]. We also plan to adopt SPASE (Space Physics
Archive Search and Extract) metadata format into WEKO.
It is noted that WEKO is used not only for an open data repository but also for a closed database among specified users byintroducing authentication system. We propose to apply Single-Sign-On (SSO) authentication via Shibboleth to WEKO, which
can be realized by customizing NC2 layer. Because Shibboleth has already been adopted by Academic Access Management
Federation in Japan (GakuNin) flexible access is available for the WEKO data.
In the presentation, we introduce our repository site, which are customized for the scientific data repository for satellite anddiscuss future works for further development.

Data Integration and Analysis System Program (DIAS-P) is building the data infrastructure by collecting and managing various
global environment data and metadata like observation data and model data at home and abroad, for the purpose of interoperability
data usage. To properly manage a variety of data, it is important to create and manage the metadata of the data. We are creating
metadata for the data in DIAS at the dataset level in the format of ISO19115/19139. We are also collecting the data from related
data centers and building the search system for searching the metadata from various fields and in various formats.
To smoothly share the metadata in DIAS and in order to implement the appropriate search for metadata in various formats, weare aiming at developing and operating a metadata mediation system, to centrally manage the metadata and make the metadata
usable for the applications like the search system. To unify and align the metadata formats, we are using GI-cat which is a software
for broker catalog services. Also, the metadata mediation system aim to manage the information associated with the metadata(metadata of metadata) including the mapping information between English and Japanese metadata. We are considering on theusage of GI-cat in our case including the possibility of the update of GI-cat itself, by discussing with the members of ESSI-Lab,
who are the developers of GI-cat. We introduce our attempt on the format conversion of actual metadata from the collaborative
institutes, and metadata sharing in DIAS using GI-cat. Furthermore, in this presentation, with the treatment of various metadata in
DIAS, we also introduce our attempt on the creation of DOI (Digital Object Identifier) to the datasets in DIAS. We are discussing
the mapping between the metadata created for DIAS datasets and the metadata required for DOI registration.

As is well known, Japan is one of the most seismically active countries in the world. For this reason, government and a numberof research institutes have been developed both basic and applied seismological researches extensively. However, along withthese studies, to live in such country it is also important that each individual gets prepared to protect his/her home and family
from future disaster. For this purpose, it is necessary to promote disaster awareness of people. In addition, preparedness priority
should vary by region and/or community. Therefore, in this study we selected small community in Yokohama and developed avisible disaster mitigation network so that people in the community actively participate seismic monitoring and share information.
Yokohama is located in the southern Kanto where the three plates meet, and there is no question about suffering a devastating
earthquake in the future. The selected area is reclamation district and there are a number of old apartments where a big populationof elderly person lives alone. So we utilized the network as home monitoring system for them as well. The network consists ofa server located in the main office and distributed tiny sensor units. Each unit composed of QCN sensor provided by Stanford
University and Raspberry Pi. The size of unit is about 30 cm by 10 cm by 10 cm and it is easily installed at houses and schools.
Once the sensor detects the ground motion, the data is sent to the server and calculate seismic intensity and evaluate the status ofbuilding. In our presentation we will show how we utilize the network in the community and demonstrate various applications
developed for people and school in the community.
