Providing technical solutions for realizing the FAIR Principles is one important goal in working package FAIR Data Commons. The vision is to establish internationally discussed and accepted concepts, standards and interfaces within the Helmholtz Association, in the first step for harmonizing metadata handling within the association and later on beyond Helmholtz. The majority of services presented here are strictly following existing standards and recommendations. Other services are supposed to realized basic processes for realizing the FAIR Principles technically and can be understood as suggestion for custom implementations.

All published services of working package FAIR Data Commons are available as a public source code repository under Open Source license.
