what is local system that export metadata( EPD, local data management system, Molgenis, Beacon? XNAT (health ri repository, img2catalog)
Introduction
Enabling your institute's local system to directly expose metadata creates the strongest connection between your original data and publicly available information. This setup means that responsibility for maintaining this metadata is kept at the source, whether handled by software or people. Achieving this requires either a system already supporting this feature or deep knowledge of the source system and the availability of software engineering capacity to extend the functionality of the system.
When considering sharing your data with the public, think about using local systems like local data management systems, Molgenis, or XNAT. These systems establish a direct pathway between your original data and public information, ensuring that you're in charge of managing your data within your institute.
...
MOLGENIS partly supports the FAIR principles, including the FAIR Data Point (FDP) extension. The FDP implementation within MOLGENIS EMX2 complies with the latest v1.1 specification of the FAIR Data Point. This means that MOLGENIS allows you to establish a connection with a FAIR Data Point. For setup and configuration instructions, please refer to the https://molgenis.github.io/molgenis-emx2/#/molgenis/dev_fairdatapoint?id=fair-data-point.
Usage example
MOLGENIS offers extensive customization options and the ability to develop applications, as demonstrated by the BBMRI-ERIC project.
XNAT img2catalog
XNAT img2catalog is a tool that extracts metadata from XNAT instances and generates DCAT-AP 3.0 metadata. Each XNAT project is treated as a separate dataset. While this tool lacks features for updating existing datasets, it provides a means to connect your data with a FAIR Data Point. However, it's important to note that the tool currently does not fully utilize all aspects of FAIR data principles, such as updating existing datasets and setting language for fields.
