MOSES Data
The MOSES Data Management (DM) team is coordinated by the Helmholtz Centre Potsdam GFZ German Research Centre for Geosciences and consists of representatives of all participating centers. The tasks of the MOSES DM team consist of:
- the elaboration of and ensuring compliance with the MOSES Data Policy,
- the provision of a tool to support scientists in preparing data management plans (DMPs)
- the development of a Data Management Infrastructure to allow access to MOSES data.
The Data Policy, the DMP Tool and the Data Management Infrastructure will be implemented in an iterative development process, in which the requirements from the event working groups will be prototypically realized. As part of the MOSES implementation phase, a data management concept and respective data management tools are developed and subsequently tested and evaluated during MOSES campaigns. Here, the distributed nature of the MOSES infrastructure components poses challenges for the integration of its similarly distributed data. Therefore a centralized metadata collection management is a prerequisite if MOSES data is to meet the scientific criteria of tracing specific products back to their acquisition.

The MOSES data management platform
architecture is based on common and standardized data models,
protocols, and encodings. It fosters the re-use of existing
software systems and components available at Helmholtz Centers and
allows access to multidisciplinary datasets. Through the use of
standards, this architecture supports the integration of long-term
monitoring networks and platforms providing complementary data for the
event-driven campaigns.
For all MOSES campaigns
and datasets, metadata is collected based on ISO/OGC standards. The
metadata collection is facilitated via campaign-specific data management
plans (DMPs) that record roles and responsibilities as well as the
volume, characteristics, processing and use of data and data flows
before, during, and after campaigns via an online tool (https://moses-dmp.gfz-potsdam.de).
For
subsequent (meta)data discovery and access, we use the OneStop search
software of the National Oceanic and Atmospheric Administration (NOAA
OneStop, version 2.0.6). The NOAA search software relies on modern web
technologies and ensures interoperability through web services based on
RESTful APIs. The MOSES Data Discovery Portal (https://moses-data.gfz-potsdam.de)
integrates these services into a graphical user interface that allows a
user-specific search and discovery of campaign metadata and datasets,
their initial visualization, and respective download. To further
support, optimize, and semi-automate the data management workflows,
additional tools for fast data provision, quality control and assurance,
and quick visualization will be developed.
