In May, our Birthday Campaign put the basic service PID4NFDI in the spotlight. In the summary below, you can find out more about the PID Coordination Hub, the service’s community engagement and their provided resources.

PID Coordination Hub

It’s common sense that Persistent identifiers (PIDs) are central to FAIR research data management. However, different disciplines and different resources result in diverse requirements and the various NFDI consortia have different levels of maturity in PID implementation. To overcome these differences, PID4NFDI aims to enhance PID integration within NFDI consortia, considering varying provider maturity levels and community adaptation. Their aim is to foster the impact of PIDs by improving metadata quality and interoperability through technical, organisational, and strategic measures. 

The service brings together the extensive expertise of various organisations, which jointly run PID4NFDI together: DataCite, the  Gesellschaft für wissenschaftliche Datenverarbeitung mbH Göttingen (GWDG), the Helmholtz Open Science Office and the TIB – German National Library of Science and Technology. 

At the very centre of the service of PID4NFDI is the PID Coordination Hub. It serves as a central support infrastructure for managing persistent identifiers within Germany’s National Research Data Infrastructure (NFDI). On its platform, the Hub provides consulting and practical support in the key areas of persistent identifier implementation, interoperability, governance, training/support, and community engagement. It serves as a central entry point for users of the PID4NFDI service portfolio and aims

• to enable repository managers to optimise the integration of PIDs into their workflows,
• to support trainers in the FDM field with materials and information,
• to demonstrate to researchers, decision-makers, and funders the added value of PIDs for their own workflows and processes,
• to provide best practices for different use cases to NFDI multipliers like sections and working groups.

The goal of the interoperability aspect is to ensure that different PID systems, repositories, metadata schemas, and research infrastructures can work together cleanly across disciplines and platforms. It offers support for metadata quality, guidelines for metadata harmonisation, and focuses on resources from already existing use cases.

The metadata key area concentrates on metadata quality, standardisation, and includes practical guidance and services to help repositories improve their metadata maturity.  Since the hub does not aim to become a new PID registration agency itself, it also helps to address government issues. It coordinates and simplifies access to existing PID ecosystems and provides helpful policies and recommendations. More materials and recommendations are managed in the areas of training, support and community engagement. There you can find a wide range of training materials, guides, tutorials, use cases, best practices and more as well as information about events and opportunities for consultations. 

As you see, the PID Coordination Hub is a multifaceted and complex tool designed to support the entire NFDI community with regard to PIDs, and it will be continuously developed.

Community Engagement

PID4NFDI does not only provide information about persistent identifiers (PIDs), but also helps researchers and consortia to apply them in practice and to build a connected support network around them. On their website you can find a broad overview of PID4NFDI’s community work from real-world use cases, thematic focus groups, open support formats, and services tailored for NFDI consortia. To increase visibility, and facilitate networking, the service offers also an overview of the PID services provided by the NFDI consortia.

PID4NFDI is currently in the integration phase, which is expected to be completed by the end of the year. The goal of the integration phase is to further develop the service into a mature and functional solution that will have been adopted by an initial group of organisations and institutions for their day-to-day operations.

You can see an overview of the consortia with which PID4NFDI has already set up collaborations under Use Cases. The Use Cases are practical examples of how PID4NFDI persistent identifier services can be applied in research workflows. It helps visitors understand where persistent identifiers add value in everyday scientific practice, especially when they need to improve findability, interoperability, and long-term access to research outputs.

In addition to the use cases, the service has established two focus groups in 2025 to discuss the integration of persistent identifiers (PIDs) into the research data lifecycle through data management plans (DMPs) and electronic lab notebooks (ELNs). Each group held three virtual meetings from spring through summer, culminating in a joint in-person workshop in Berlin in September 2025. This report summarizes findings on metadata workflows, PID integration pathways, and technical interoperability requirements. These findings establish a foundation for two incubator projects that will launch in 2026 in collaboration with TS4NFDI. 

If you're looking to connect with PID4NFDI in a different setting, you can use two additional formats under “Support”: The Open Hour and the Consultation Hour. 

The Open Hour is an informal gathering where the project invites you to learn more about its mission. It is an opportunity to foster engagement and interact with the project in a casual, drop-in manner. During the Open Hour, the project’s work is showcased, and the community is engaged. The Open Hours are designed to be accessible to everyone, regardless of background or connection to the project.

The events are held on a regular basis at different times on different days. Information about the upcoming meetings in 2026 can be found on the PID4NFDI website.
Furthermore PID4NFDI offers you 1:1 consultations sessions to explore PID-specific challenges related to your service and/or use case. The consultation hour offers a tailored approach to address your requirements. Please use the contact form to ‘book’ a consultation hour with PID4NFDI. Inquiries should contain 3 date options for meeting time. 

As you can see, PID4NFDI values communication with the community highly in order to understand and support its needs and technical requirements. In addition to their support services, we would also like to highlight two upcoming workshops:

PID4NFDI Community workshop on IGSN Use Cases

Date: June 04, 2026
Time: 10:00 AM to 1:00 PM (CEST)
Registration

The International Generic Sample Number (IGSN) is a globally unique and persistent identifier (PID) for physical objects—ranging from rock samples and sediment cores to biological specimens and cultural heritage objects. This event brings together colleagues from NFDI consortia who are already actively using IGSNs and those planning their implementation. The goals are:

• Community Exchange: Share hands-on use cases and foster networking between different research domains.
• Service Overview: Get an update on available IGSN services and existing infrastructures.
• Shaping Resources: Provide direct feedback on current training materials and guidance documents.
• Future Collaboration: Identify community needs and discuss future formats for structured exchange.

Online Workshop: Building Confidence with Research Metadata at Scale

Date: June 15, 2026
Time: 10:00 AM to 12:00 PM (CEST)
Registration

This hands-on, online workshop empowers research support professionals to move beyond static views of metadata and actively interrogate, assess, and act on DOI metadata at scale using the DataCite API. Using the DataCite metadata schema as a practical reference point, participants will work directly with real DOI metadata to explore which metadata elements most strongly influence discovery, reuse, trust, and decision-making. While DataCite is used as a reference implementation, the approaches and principles discussed are applicable to other PID-based and metadata-rich infrastructures.

Resources provided by PID4NFDI

The PID Training Materials & Guides page provides a valuable collection of resources in one convenient place. It points to publicly available handbooks, cookbooks, documentation, and guides from different institutions, with the aim of helping users find reliable PID-related training material in one place. The collection will keep growing to reflect the needs of the NFDI research communities. The team welcomes suggestions.

 The materials are sorted in six sections:

• Introductions, Overview & PID Ecosystem
• DOI & DataCite
• ORCID & ROR
• ePIC, Handle & ARK
• Instruments & Software Identifiers
• Collections & Portals

For better findability, additional filter options like type of resource, provider, domain, language, proficiency level and PID type are available to help you to find the right training resources for your matter.

In addition to the training materials, PID4NFDI also provides an overview of their most relevant Publications. For a full and comprehensive list of all their research outputs, you can browse through PID4NFDI’s Zenodo Community. In addition to their own outputs, the service also maintains the PID4NFDI Zotero Library — a publicly accessible, collaborative reference collection on Persistent Identifiers and FAIR Research Data Management. This shared knowledge base curates scholarly articles, reports, and guidelines from across the PID ecosystem. 

As you can see, the team of PID4NFDI put a lot of effort into collecting and providing useful resources about the usage of PIDs. All this extensive knowledge was condensed in the PID4NFDI Cookbook. This resource supports you in getting started with PID registration and usage. Besides practical guidance on first steps for individuals and organisations how to implement PIDs in their workflows, it also provides information about what PIDs are, their importance in ensuring long-term access and citation of digital resources, and how they help in maintaining research data, publications, and other digital assets.

In the former posts, you have learned that the service aims to enhance PID integration within NFDI consortia, considering varying provider maturity levels and community adoption. Therefore PID4NFDI developed the PID Coordination Hub as a central entry point for users of the PID4NFDI service portfolio. Last week we showed you a broad overview of PID4NFDI’s community work from real-world use cases, thematic focus groups, open support formats, and services tailored for NFDI consortia. Today, we would like to shed some light on the training materials and publications of PID4NFDI. 

We hope these posts have made it clear that PID4NFDI is the perfect point of contact for any questions you may have about using PIDs. Grab a coffee and browse through the wealth of resources. If you still have questions after that, the team is here to offer help and advice. Feel free to take another look at last week’s article with information about their community engagement.

2026-05-21

How do you actually manage the virtual identities within your own community? And what do you do when external partners suddenly come into the picture and need temporary access to data and services? Have you already decided on a Community AAI (Authentication and Authorisation Infrastructure) for your online service? Are you (open enough) to the InfraProxy? Or would you rather take a step back: what exactly is a CAAI? If you’re asking yourself these or similar questions, our upcoming event is just the thing for you.

The IAM4NFDI team is organising a user meeting for users and those interested in the Community AAI software that they offer across the NFDI (AcademicID, didmos, RegApp and Unity). They will start with a joint session on general topics. Afterwards, the team will split the video conference into rooms for each CAAI.

 They look forward to discussing the following topics with you:

• What does a CAAI do?
• What can I do with a CAAI?
• How do I connect a service to a CAAI?
• When does it make sense to connect a service to the InfraProxy?
• What is community management all about?
• What policies do I need?
• What’s new in my CAAI?
• Exchange between users

 No registration is required – just drop by!

When? Thursday, 18 June, 2026, 2 pm to 5 pm

Where? In this Zoom meeting

2026-05-05

In the spirit of our Birthday Campaign, IAM4NFDI was our April spotlight. We took a deep dive into what IAM4NFDI has been working on, where it is usable already, and what their plans for the future are. 

IAM4NFDI Explainer Video

Starting with the basics: What exactly is IAM4NFDI? IAM4NFDI is concerned with connecting and expanding existing and emerging Identity and Access Management (IAM) systems in a way that researchers from different domains and institutions are able to access digital resources within NFDI as easily as possible, including access to and exchange with external infrastructures and resources like the European Open Science Cloud (EOSC). A decentralised, federated IAM is required. This way, users from approx. 400 German research and higher education institutions plus approx. 5000 home organisations worldwide – number increasing – will be able to access services and resources provided by the NFDI Community Authentication & Authorisation Infrastructure (AAI).

To get a vivid impression of how IAM4NFDI works, we would like to draw your attention to our explainer video. It helps you to discover how IAM4NFDI is revolutionising access to digital research resources! By connecting and expanding Identity and Access Management (IAM) systems, this initiative enables researchers across Germany and worldwide to seamlessly access tools, data, and services within the National Research Data Infrastructure (NFDI). Learn how the decentralized, federated approach ensures secure and easy integration with external platforms like the European Open Science Cloud (EOSC), benefiting thousands of institutions and researchers globally.

Check out the video on Youtube.

IAM4NFDI is the first service successfully making it to the final phase of our funding process. At this point, the vision is to transition the established NFDI Authentication and Authorization Infrastructure (NFDI-AAI) consisting of the Community AAI services, the Infrastructure Proxy, and its Policy Framework into an operational, reliable, and sustainable Basic service. Building upon the successful integration of most NFDI-Consortia, this phase focuses on scaling the service, enhancing the user experience, and supporting the integration of more complex services through incubator projects. IAM4NFDI will continue to proactively integrate the evolving standards and technologies, especially those relevant for the EOSC AAI, to meet future needs of the NFDI in its role as the German national node. To ensure long-term viability, we are establishing a durable operational model with the service providers and want to shape and integrate into the future sustainable governance and funding strategies in close cooperation with the NFDI association and Base4NFDI.

Incubator Dashboard

Generally, the IAM4NFDI incubators aim to develop, foster, and mature new ideas in the field of identity and access management. The projects investigate new technologies that currently have no place (yet) in the services ecosystem of the IAM4NFDI project, including testing and experimenting with potential new features for existing CAAI solutions. An incubator project typically runs about 6 months and employs an agile methodology to enable rapid development of ideas. Throughout regular "Calls for ideas", project teams can apply to become an incubator project by filling out a template and describing their idea. If the incubator is approved, the IAM4NFDI team assigns a responsible CAAI expert to the incubator project who is the main contact point for the project team during the incubator cycle. Once a month the project members will give a short update on the current state within a sprint demo meeting and can exchange with other incubator project teams.

The incubator dashboard aims to represent a broad view on all developments in identity and access management within the different NFDI consortia and beyond. 

But who actually curates the dashboard? The so-called dashboard members. They are project members of IAM4NFDI and/or experts from the different CAAI solutions. They evaluate new ideas and provide advice to the work package lead. Furthermore, they are responsible for reviewing activities at the end of each incubator cycle and providing recommendations on how to proceed. The incubator team presents their results regularly to the dashboard's and the wider community via monthly sprint demos.

A great asset of the dashboard are the filter options. Users can filter their search by topic, incubator status, cycle, and NFDI consortium or external incubator projects. A wide variety of topics is covered, namely Identity and Access Management, Standards and Protocols, Security and Privacy, Infrastructure support, Integration support, and Consultancy. Brief definitions of each topic can be found on the top half of the dashboard, enabling the users to fully grasp the content and significance of the incubator projects.

Furthermore, a timeline illustrates the history of past incubator cycles as well as current and future cycles. As you can see, cycle 5 is currently running and there is another chance to submit a proposal for an Incubator project in cycle 6, starting in August this year. Information on how to submit a new idea, including the template that needs to be filled out, is provided in a downloadable PDF. Don't miss out on the next call for incubators – follow our LinkedIn account to get a notification!

So, perhaps you and your consortium will take the chance of working closely together with IAM4NFDI in the final cycle! 

Authentication and Authorisation Infrastructure for the NFDI

IAM4NFDI provides an Authentication and Authorisation Infrastructure (AAI) for the NFDI, called NFDI-AAI. But what does this actually mean? The NFDI-AAI connects and expands existing and emerging Identity and Access Management (IAM) systems in a way that researchers from different domains, communities and institutions are able to access digital resources within the NFDI as easily as possible, including access to and exchange with external infrastructures and resources such as the European Open Science Cloud (EOSC).

To give you some more context: The IAM team has built its work on successful previous (international) projects, including AARC and the EOSC-Taskforce on AAI Architecture as well as numerous German endeavours:

• Helmholtz AAI by HIFIS, which enables seamless login and cross-institutional group management to Helmholtz Cloud services.
• AcademicID by GWDG, which is used to offer all IT services of GWDG to education in Lower Saxony.
• didmos by DAASI International, which integrates expandable open source modules that can be custom tailored to infrastructures.
• RegApp by KIT, which is used to provide access to several educational and infrastructure services to academia in Baden Württemberg.

Following the three-phase-model of Base4NFDI, the IAM4NFDI team has successfully completed the Initialisation and Integration phase. The Integration phase focussed on the operationalisation of the components of the NFDI-AAI and on enabling support for as many NFDI use-cases as possible. As for the latter, numerous services have been integrated into the NFDI-AAI over the course of four incubator cycles. In this way, the vast majority of the research communities represented by the NFDI Consortia were able to connect to the NFDI-AAI. In addition to the incubators, the collaboration with the AAI operators of the EOSC EU Node and the LifeScience AAI were intensified through numerous meetings, during which preparations were made for the integration activities planned for the Ramp-up phase. 

However, not only the technical aspects are crucial when building and sustaining a service of this kind, but also community engagement, including continuous outreach and training. 

Therefore, we would like to draw your attention to a workshop the IAM4NFDI team has planned for June. This is your chance to hear directly from IAM experts about how best to integrate your services into the NFDI-AAI and how to implement login and authorisation concepts!

What? Meeting for users of and people interested in community AAI software offered by NFDI (AcademicID, didmos, RegApp und Unity). The workshop is organised by the IAM4NFDI team.

When? Thursday, 18 June 14:00 - 17:00 CEST 

Where? Online via Zoom, you can join without a registration using this URL.

The workshop addresses the following questions and topics:

• What does a CAAI do? 
• What can I do with a CAAI?
• How can I link a service to a CAAI? 
• When is it useful to link a service to an InfraProxy?
• What’s the purpose of community management?
• Which policies do I need?
• Is there any news regarding my CAAI?
• Communication and exchange between users

The workshop will start with an introduction to the topics, followed by break out sessions for each CAAI. 

The team is looking forward to welcoming you! 

And of course we also want to share with you what’s next for the NFDI AAI. The IAM4NFDI team is currently in the Ramp-up phase, focussing on scaling the service. This means that IAM4NFDI will continue to proactively integrate evolving standards and technologies, especially those relevant for the EOSC AAI, to meet future needs of the NFDI in its role as the German National Node for EOSC. To ensure long-term viability, sustainable operational and governance models including funding strategies will be developed in close cooperation with the NFDI association and Base4NFDI.
