Federation, not duplication
CRediT is maintained by the NISO CRediT Standing Committee under ANSI/NISO Z39.104-2022; CASRAI originated CRediT and transferred its stewardship to NISO in the 2020 wind-down, and continues to steward the wider Dictionary that CRediT sits within. That same 2020 handover distributed CASRAI's other assets to euroCRIS (CERIF) and CODATA (RDM Terminology). CASRAI cross-walks and incubates vocabulary against partner standards rather than duplicating their work.

Each card opens the dedicated federation page with the substantive vocabulary slice, any historical ties to CASRAI, and where CASRAI's standards interoperate with theirs.
NISO
United StatesCRediT stewardship
Stewards CRediT as ANSI/NISO Z39.104-2022 since the 2020 handover. CASRAI mirrors CRediT in the dictionary with sameAs pointers.

EuropeCERIF / CRIS interop
Stewards the CASRAI Catalogue of Elements as enrichment to CERIF. The Catalogue lives at github.com/EuroCRIS/CASRAI-Dictionaries.

Stewards the Research Data Management Terminology (formerly the CASRAI RDM Glossary).

InternationalPerson PID
Persistent identifier for researchers. CRediT-tagged works propagate automatically into ORCID records via Crossref.

DOI registration for scholarly publications. Schema 5.5+ carries CRediT in deposit metadata.

DOI registration for datasets, software, and instruments. Cross-walk between CRediT and DataCite contributorType.
Federation page →RDA — Research Data Alliance
InternationalResearch-data WG umbrella
Multi-WG umbrella for research data infrastructure. CASRAI's vocabulary is built to interoperate with outputs from several RDA working groups (DMP Common Standard, FAIR4RS, PIDINST, Indigenous Data Sovereignty IG, etc.).
Federation page →ARDC
AustraliaRAiD registration authority
Registration Authority for the Research Activity Identifier (RAiD, ISO 23527:2022). CASRAI's persistent-identifiers domain cross-walks RAiD vocabulary into the dictionary.

Key dictionary terms that cross partner boundaries
Twelve terms whose canonical definitions are stewarded by one external standards body and consumed by several others. The dictionary mirrors each via a sameAs pointer to the steward, keeping us in sync without re-deriving.
Dictionary term
FAIR principles
Findable, Accessible, Interoperable, Reusable — the canonical data-stewardship principles, widely embedded in federation cross-walks.
Dictionary term
CARE principles
Collective Benefit, Authority to Control, Responsibility, Ethics — the GIDA-stewarded Indigenous-data counterpart to FAIR.
Dictionary term
DORA
San Francisco Declaration on Research Assessment — the 2012 declaration that triggered the assessment-reform federation thread.
Dictionary term
CoARA
Coalition for Advancing Research Assessment — the pan-European reform initiative federating dozens of national funders and universities.
Dictionary term
Plan S
The cOAlition S funder initiative requiring open-access deposit of funded outputs; cross-cuts every standards body CASRAI's dictionary interoperates with.
Dictionary term
cOAlition S
The funder coalition behind Plan S; CASRAI federation work routinely intersects Plan-S deposit and journal-flipping requirements.
Dictionary term
EOSC
European Open Science Cloud — the federated infrastructure layer that consumes much of the dictionary indirectly via OpenAIRE.
Dictionary term
OpenAIRE
Pan-European scholarly knowledge graph; consumes Crossref + DataCite + repositories and is a federation partner candidate.
Dictionary term
DataCite
DOI registration for datasets, software, and instruments; cross-walk between contributorType and CRediT roles.
Dictionary term
Crossref
DOI registration for scholarly publications; schema 5.5+ carries CRediT in deposit metadata.
Dictionary term
ORCID iD
The 16-digit persistent identifier for an individual researcher; the auto-propagation sink for Crossref-deposited works.
Dictionary term
RAiD
Research Activity Identifier (ISO 23527:2022) — ARDC is the registration authority; CASRAI cross-walks the vocabulary into its persistent-identifiers domain.
Related domains: persistent identifiers, responsible assessment, Indigenous data & CARE, data infrastructure.
Federation FAQ
How the federation model works
What does CASRAI mean by "federation, not duplication"?+
CASRAI does not re-derive vocabulary that another standards body already publishes. Instead we point at canonical definitions via sameAs links, cross-walk our terminology to theirs, and incubate new vocabulary only where no existing steward owns the slice. The 2020 handover to NISO, euroCRIS, and CODATA formalised this distributed-stewardship model.
What was the 2020 stewardship handover?+
In 2020, CASRAI passed stewardship of three discrete vocabulary lines to dedicated stewards: the Contributor Roles Taxonomy moved to NISO, which now publishes it as ANSI/NISO Z39.104, the Catalogue of Elements moved to euroCRIS as CERIF enrichment, and the Research Data Management Terminology moved to CODATA. The joint statement is on /federation/joint-statements.
Why are some partner bodies referred to only by name on this hub?+
On this hub page we reference each organization by name and point at the dedicated /federation/<slug> page for the substantive detail. The per-partner page is where the cross-walks, historical ties, and integration touchpoints live. This keeps the hub navigable instead of duplicating the per-partner content.
Does CASRAI maintain the cross-walks itself?+
Yes. CASRAI publishes cross-walks at /federation/cross-walks for the major mappings: CRediT ↔ DataCite contributorType, CASRAI terms ↔ CERIF entities, RDM Terminology ↔ FAIR principles, and several others. Each cross-walk is versioned alongside its source vocabularies; deprecations carry forward in both directions.
How do RDA working groups fit into the federation?+
The Research Data Alliance is a multi-WG umbrella. CASRAI's vocabulary is built to interoperate with the outputs of several specific RDA working groups (DMP Common Standard, FAIR4RS, PIDINST, the Indigenous Data Sovereignty IG, others) rather than treating RDA as a single counterparty. The /federation/rda page lists the cross-walks and which dictionary terms trace to each WG's upstream definition.
Can a new partner be added to the federation?+
Yes. The federation deliberately grows. CASRAI staff review proposals from standards bodies that steward a vocabulary slice complementary to existing partners. Proposals route via /get-involved; the bar is a recognised steward role, a published vocabulary or schema, and willingness to maintain a documented cross-walk back to the dictionary.
