The Policy Development Kit (PDK) version 2 identifies five main target audiences, functionally following the AARC BPA 2025 hierarchy and identifying (1) ‘Research governance’ as a foundational area. (2) ‘Users’ are (human) end-users who participate in a collaboration, are identified via (3) ‘identity’, i.e. external identity providers and the identity layer of the BPA, to be granted access by (4) ‘collaboration management’, to (5) ‘infrastructure integration and service providers’; in the BPA the infrastructure integration components, site-local integration components, and the actual service providers.
Policies in PDK version 2 are standards to which adherence can be asserted and that can be assessed and validated – for example as trust marks – and that are endorsed by AEGIS and considered ‘standards track’. Policies also are endorsed by the organisation at the appropriate level of management, and express a commitment of adherence by the organisation’s management. These are indicated in a roman font in the graphic below. The processes and procedures, being templates, are reference implementations where we assume these to be specialised for specific deployments. In the diagram these are indicated in italics. The semi-opaque elements are relevant, but fall outside of the scope of the PDK, which targets the authentication and authorisation infrastructure. But even if, for example. identifying the 'why and what' of your research collaboration (your 'primary assets') may not be AAI per-se (and hence greyed-out), it is very useful to know that before embarking on your AAI journey!

The AARC PDK consists of templates - documents where the core content is either highly determined or should be treated as 'immutable' for better interoperability - and guidelines - helping research collaboration, infrastructures, and service providers with their own procedures and practices, where adopting good practices rather than the exact wording of a policy or procedure is the key value for interoperability. A quick overview of the 'getting started' templates and guidance documents is given here below.
| Document | AARC template for interoperability | Examples where no template is recommended for interoperability purposes |
|---|---|---|
| Membership management | Membership Management | |
| AUP | WISE AUP | |
| Privacy Policy | REFEDS privacy notice, UK-IRIS | |
| AAOPS | Attribute Authority Operational Security | |
| Security Operational Baseline | Security Operational Baseline | |
| Incident response procedure | EOSC, UK-IRIS, AARC federated incident response procedure |
Smaller and mid-sized communities may opt to offload some of the more complex aspects of authentication and authorisation to dedicated AAI service providers. And if you operate your own AAI core components, both your users and resource providers may want to have some assurance about the trust and security posture of your AAI platform. The Snctfi suite is the set of assessable and verifiable policies and procedures in the PDK that AAI platform providers can use to make the trustworthiness of their systems transparent to users and relying parties alike.
Like Sirtfi for security incident response, Snctfi provides a self-assessment framework, but having this assessment peer reviewed brings several benefits. For one, it increases the trust others have in your platform and your assessment, making it easier for ‘as-a-service’ operators to engage with new collaborations and infrastructures. And it brings advantages to yourself as well, as you can compare notes with your peers and become better together through shared learning.
AARC does not endorse any specific AAI platform or platform provider. By asking Snctfi specific information you can inform yourself about the suitability of the provider of your choice, and work with them to ensure your bases are covered by a secure, resilient, and interoperable AAI.
The first AARC Policy Development Kit, released in 2017, comprised a set of nine reference documents (mostly templates) addressing the construction and operation of community AAIs in the original AARC "2019" Blueprint Architecture, based on the Community First Approach. A mix of policies and procedures, its primary audience was primarily larger-scale research collaborations, expected to review, augment, and specialise the templates for their own use. With the policy development kit being created prior to or in parallel to other work in the community at large, it duplicated some aspects (privacy in REFEDS DPCoCo, or incident response work parallel to the eduGAIN Security Handbook), while being overly complex for smaller collaborations. Work by the Australian Access Federation, the AARC Community, and in REFEDS, WISE, IGTF, and the e-Infrastructures helped restructure the PDK into the model presented above.
An analysis of the improvements required on PDK v1 is included in the informational document AARC-I082 "Trust framework for proxies and Snctfi research services" (doi:10.5281/zenodo.15506826)
