• We defined Upper Atmospheric domain specific XML Schema which connects DOI & ORCID. ( https://gist.github.com/iugonet/e32526c240519e03c112)

• In reuse of dataset & data, not only cooperation of DOI & ORCID, but also domain specific dainty-grained metadata is needed.

Characteristics of the upper atmospheric research1.There are various phenomena over a wide area from the earth surface to the space2.Many physical parameters need to be observed3.Various variations including solar cycle, tidal cycle, gravity waves, etc. are overlapped

•Sufficient for Data Publication & Citation purpose.

•Insufficient for Scientific reuse purpose.

•No detailed metadata (e.g., Geolocational properties),

•No Role info. of the Contributor.

•Coarse-grained metadata. (The min. unit is dataset)↓

Necessity for domain specific metadata for reuse purpose.

•Sufficient for Scientific reuse purpose.

•Detailed metadata (e.g., Geolocation Info., Calibration Info.),

•Human Resource Info. with Role (e.g., PI, Archive Specialist)

•Dainty-grained metadata. (The min. unit is data file)↓

This monain specific metadata helps reuse dataset & data.Scientist derive from their info. to “Derived and Recombined Data”.

Science is changing because of the impact of information technology. Experimental, theoretical & computational science are all being affected by the data deluge, and a fourth, “data-intensive” science paradigm is emerging.

Necessity of a Metadata Database

“All Scientific Data Online” futureincrease Scientific information Velocity.

Construction steps of the left pyramidal structure:1.To construct Data Publication & Citation,2.To construct reuse data framework,3. - More. Some steps are needed.

We considered the cooperation of metadata & identifiers which required for steps 1 & 2.

IUGONET provides a new research platform that enables Metadata for ground-based observation data to be shared.In addition, IUGONET developed analysis software to access and analyze data in an integrated fashion.

What is Metadata in this field?Metadata are defined as that describe certain information of our data (location, period, Instruments used, data location(URL)).
