Digital Geochemical Data Infrastructure (DIGIS) for GEOROC 2.0

• Applicants: Professor Dr.-Ing. Bela Gipp; Professor Dr. Matthias Willbold; Professor Dr. Gerhard Wörner
• Subject Area: Geology ; Mineralogy, Petrology and Geochemistry
• Term: since 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 437919684

GEOROC was mapped to the ODM2 data model and documented in the PostgreSQL database management system. The vocabularies are harmonized with published external vocabularies, units and analysis methods. For the exchange of data and metadata, a RESTful API was implemented that complies with the GeoSciML data transfer standard. A website with more flexible query options and improved data visualization is in progress. The project strictly follows the principles of open science, uses free and open-access resources and makes all data and software products available. All coding and background information for data migration, API access, IT resources and developments are provided as open source software. New data were curated and he connection to the EarthChem portal was re-established. The new funding phase aims to establish the new IT data infrastructure with a series of new tasks: Task 1-1 continues the previous project on semantics-based curation, data and metadata collection. Task 1-2 will develop network-enabled tools for web-based data entry and curation by the community. Task 1-3 will establish the digital sample archiving system with links to the GEOROC database. The new web service interface for GEOROC is API based and will offer advanced new search and filter functions (Task 1-4). We will use our "data product" to expand our community network and seek advice for further developments by activating our scientific advisory board. Task 2-1 deals with data entry, curation and quality control. An "administrator tool" (Task 2-5) requires the harmonization of vocabularies. The GeoRem database for international reference materials will be integrated into our IT infrastructure with a new interoperable data model (Task 2-2) and curated together with the International Association of Geoanalysts. This enables a new quality control tool. The "Detrital Mineral Provenance Data Base" will be incorporated into the GEOROC infrastructure (Task 2-3). Control routines will be developed to correct erroneous data entries in the database (Task 2-4). An "administrator tool" will be developed (Task 2-5) to enable data input by external curators. The work flow for data archiving in the DIGIS Repository of the GFZ Data Service (Task 2-6) will be improved. Tasks 3-1+ 2 aim to improve data exchange via the user interfaces (website and API). To this end, the GEOROC data system will be operated on a new server infrastructure. The sustainability concept will be further developed to ensure the resilience of the GEOROC data infrastructure (Task 4-1, 2). A network of curators for distributed data entry will be set up as soon as the IT infrastructure is fully established.
