About This System
We are managing vast amount of earth science data under the Data Integration and Analysis System (DIAS) Program. This system gives an overview of the entirety of a dataset by classifying the various datasets registered in the DIAS core system by field or creation method, etc. It also provides keyword and spatiotemporal search functions using metadata.
Assignment of DOIs
DIAS has started the assignment of Digital Object Identifiers (DOIs) to datasets.
The registration of DOI to Japan Link Center (JaLC) uses "JaLC Research Data API Registration System" developed by NICT and WDS National Committee of Japan.
The metadata is registered to DataCite through JaLC, and we can confirm the list of DIAS datasets with DOI at the web page of DataCite.
