  abstract = {NFDI consortia have a variety of disparate and distributed information infrastructures, many
of which are as yet only loosely or poorly connected. A major goal is to create a Research
Data Commons (RDC) . The RDC concept1 includes, for example, shared cloud services, an
application layer with access to high-performance computing (HPC), collaborative workspaces,
terminology services, and a common authentication and authorization infrastructure (AAI). The
necessary interoperability of services requires, in particular, agreement on protocols and
standards, the specification of workflows and interfaces, and the definition of long-term
sustainable responsibilities for overarching services and deliverables. Infrastructure
components are often well-tested in NFDI on a domain-specific basis, but are quite
heterogeneous and diverse between domains. LTA for digital resources has been a recurring
problem for well over 30 years and has not been conclusively solved to date, getting urgency
with the exponential growth of research data, whether it involves demands from funders - the
DFG requires 10 years of retention - or digital artifacts that must be preserved indefinitely
as digital cultural heritage. Against this background, the integration of the LTA into the RDC
of the NFDI is an urgent desideratum in order to be able to guarantee the permanent usability
of research data. A distinction must be2 made between the archiving of the digital objects as
bitstreams (this can be numeric or textual data or complex objects such as models), which
represents a first step towards long-term usability, and the archiving of the semantic and
software-technical context of the digital original objects, which entails far more effort.
Beyond the technical embedding of the LTA in the system environment of a multi-cloud-based
infrastructure, a number of technically differentiated requirements of the NFDI's subject
consortia are part of the development of a basic service for the LTA and for the re-use of
research data.3 The need for funding for the development of a basic LTA service for the NFDI
consortia results primarily from the additional costs associated with the technical and
organizational development of a cross-NFDI, decentralized network structure for LTA and the
sustainable subsequent use of research data. It is imperative that the technical actors are
able to act within the network as a technology-oriented community, and that they can provide
their own services as part of the support for also within a federated infrastructure. The
working group "Long Term Archiving" (LTA) is to develop the requirements of the technical
consortia for LTA and, on this basis, strategic approaches for the implementation of a basic
service LTA. The working group consists of members of various NFDI consortia covering the
humanities, natural science and engineering disciplines and experts from a variety of
pertinent infrastructures with strong overall connections to the nestor long-term archiving
competence network. The close linkage of NFDI consortia with experienced4 partners in the
field of LTA ensures that a) the relevant technical state-of-the-art is present in the group
and b) the knowledge of data producers about contexts of origin and data users interact
directly. This composition enables the team to take an overarching view that spans the
requirements of the disciplines and consortia, also takes into account interdisciplinary
needs, and at the same time brings in the existing know-how in the infrastructure sector.},
