Welcome to the TRR228DB

The TRR228DB is the project-database of the DFG-funded Transregional Collaborative Research Centre 228. The database is able to archive and provide all research data that are created by the project participants. This includes measured/modeled data, reports, presentations, publications, and pictures. In addition, purchased geodata is available for the project participants. All data is provided with correponding metadata. Depending on the respective rights, the download access may be restricted.

TRR228 Metadata Schema for the Description of Research Data in the TRR228DB successfully published
The TRR228DB Metadata Schema is a structured list of metadata properties chosen to describe all data in the TRR228DB with accurate metadata. The Schema is designed in compliance with the Dublin Core Metadata Initiative and DataCite (Version 4.3). It is expanded with elements from ISO 19115, INSPIRE, Data Documentation Initiative (DDI), as well as various properties appropriate to the supported data types and specific properties related to the CRC/TRR228 project background.
The Schema is available for download at DOI: 10.5880/TRR228DB.6.
