3. DIAS: Overview
The DAIS is archived big amount of miscellaneous environmental data. Those data are analyzed and integrated to provide useful information for solving environmental problems, such as climate change, natural disasters.

4. DIAS: Structure

6. DIAS: Case Study

7. Data Cleansing, QC & metadata registration by Data Provider

8. Metadata about dataset : Document-metadata
DIAS Metadata
Adopt the XML metadata used in geographic information system ISO19115 (ISO19139)
Metadata about dataset : Document-metadata
For the purpose of search for and comparison of dataset
The granule of dataset is coarse, in general, and is decided after discussion with data provider
Files which include both data and metadata (such as those in netCDF) are not included in our target datasets.
Once metadata is created, Document-metadata is automatically generated in HTML, PDF.
Data providers have to publish datasets with Document-metadata.

others)

11. DIAS Metadata Management System
A Web Application
The system manage the registered metadata at the server side. Metadata input person using this system does not need to be aware of the XML.
This system create one metadata (Japanese, English) per dataset.
The system has minimum required fields specified by the metadata schema, and recommended fields by the DIAS.
The system reduce manual input fields as much as possible.
The system avoid duplication input against language-independent input fields.
Templates:　Reference of previous created metadata and reuse
Copy-and-paste of contact information
The system does not display the automatically generating metadata fields.
The category specification field is controlled by the selection menu.
The system has the thesaurus dictionaries for supporting the user to input keywords.
The system manage data revision history and manage update history of the metadata.

12. The Workshop for DIAS metadata input
The contents of metadata cannot know except the data provider. We have held the workshop about DIAS metadata input in order to understand what kind of information should be inputted for each field of metadata. The workshop has held 2 or 3 times a year.

13. Management of Data Access Privilege
Access to and search for Document-metadata is open to public
Data Access Restrictions:
Login account is required
Free access
Agreement with data policy is required
Approval from data administrator is required
Require manual procedure for approval
Prepare an application form, assist on automatic and so on.
Others / special treatment
Contact with data administrator by or other media. If an application is approved, the user account is granted permission.
The system provides UI for data administrator to change the access privilege for individual user account.

14. DIAS registered user statistics

15. DIAS-GCI Cooperation DIAS published data is searchable and accessible
from GEOSS Portal
GCI:
GEOSS Common
Infrastructure
Export of DIAS metadata

16. DIAS data release status
GCI-DAB metadata harvest

17. DOI registration plan for DIAS data
Until the end of FY2016, we have a plan
to register a few DOIs to JaLC
(Japan Link Center).
Add a new function to DIAS metadata management system to manage DOIs.
Add DOI in each DIAS document-metadata (XML, HTML, PDF)
Convert DIAS metadata xml to JaLC xml to register DOI to DataCite through JaLC
Create a new DOI registration system from DIAS to JaLC
