Shared vocabularies for research administration.

CASRAI is a community-stewarded standards organisation, founded in 2006, that develops open vocabularies for research administration. Its flagship outputs are the CASRAI Dictionary (1,610 terms across 24 domains) and the Contributor Roles Taxonomy (CRediT, ANSI/NISO Z39.104-2022), federated with NISO, euroCRIS, CODATA, and RDA — freely reusable under CC-BY 4.0.

Explore the Dictionary, the 14 CRediT contributor roles, our standards & releases programme, or the standards CASRAI's work interoperates with.

What Is a DICOM Conformance Statement?

A DICOM conformance statement is a vendor-published document, structured per DICOM PS3.2 (Conformance), that specifies exactly which SOP (Service-Object Pair) classes a medical-imaging device or software supports and in which network role (SCU or SCP), which transfer syntaxes it can send or receive, which network and media-storage services it offers, and any vendor-specific extensions or restrictions. A document counts as a real conformance statement only if it specifies this level of protocol detail; a marketing claim of 'DICOM compliant' with no published SOP-class/transfer-syntax detail does not meet the bar, because it gives a buyer no way to verify whether two specific devices will actually interoperate.

ECCN (Export Control Classification Number)

An Export Control Classification Number (ECCN) is a five-character alphanumeric code assigned to an item, software package, or technology when it matches a specific entry on the US Commerce Control List (CCL) under the Export Administration Regulations (EAR, 15 CFR Parts 730-774), administered by the Department of Commerce Bureau of Industry and Security (BIS). The code format is: one digit (0-9) for product category, one letter (A-E) for product group, and three digits identifying the specific CCL entry and reason(s) for control. Items subject to the EAR that match no CCL entry are not assigned an ECCN; they are designated EAR99 instead.

CGA Pamphlet P-1

<p>CGA Pamphlet P-1 (<em>Safe Handling of Compressed Gases in Containers</em>) is the Compressed Gas Association's industry consensus standard covering the in-plant handling, storage, and use of compressed gas cylinders, portable tanks, and similar containers. It is incorporated by reference into US federal law at 29 CFR 1910.101(b), OSHA's general industry rule for compressed gases, which states that 'the in-plant handling, storage, and utilization of all compressed gases in cylinders, portable tanks, rail tankcars, or motor vehicle cargo tanks shall be in accordance with Compressed Gas Association Pamphlet P-1-1965.' A lab, hospital, or industrial site is operating 'under CGA P-1' whenever its cylinder-securing, storage-segregation, and handling practices trace back to this pamphlet's requirements, whether an EHS policy cites the pamphlet by name or simply cites the OSHA regulation that incorporates it. Because OSHA's text still names the 1965 edition specifically, facilities should treat that citation as the enforceable floor and CGA's more recent revisions (the association updates its pamphlets periodically, as it does across its full P-, C-, V-, and S-series) as current good-practice guidance layered on top.</p>

CGA Fittings

A CGA fitting is the standardized valve outlet/regulator inlet connection, identified by a CGA (Compressed Gas Association) three-digit number under CGA V-1 / ANSI B57.1, that is matched to a specific gas or group of compatible gases so that a regulator built for one gas cannot readily be connected to an incompatible one. It answers 'will this regulator connect to this cylinder,' a separate question from the gas identity or the cylinder size.

USP Class VI Certification

USP Class VI certification is a designation that a specific plastic material or component has passed the most stringent tier of biological reactivity testing under United States Pharmacopeia (USP) General Chapter <88>, "Biological Reactivity Tests, In Vivo." Chapter <88> defines six plastic classes (I through VI) based on which combination of three in-vivo bioassays -- systemic (acute) toxicity injection, intracutaneous reactivity, and implantation -- a material passes, and at what extraction rigor. A material reaches Class VI, the highest of the six classes, only when it passes all three bioassays using extracts prepared at the most demanding temperature/duration condition the material can withstand without degrading. Certification is specific to a tested formulation and manufacturing process, not a general property of a polymer family: it is not automatically inherited by variants, colorants, regrind blends, or downstream-sterilized versions of the same base resin, and passing Class VI does not by itself satisfy the broader ISO 10993 biocompatibility program most finished medical devices require.

Type I Borosilicate Glass

Type I borosilicate glass is a pharmaceutical primary-packaging glass classified under USP General Chapter <660>, Containers—Glass, as meeting the highest hydrolytic-resistance category through borosilicate composition and a passing result on the chapter's powdered glass test. A glass lot or container qualifies for the 'USP Type I' designation only once tested and documented under this method — borosilicate composition is necessary but not sufficient on its own; the designation follows from a specific tested result, not from raw material alone. It is distinct from the general-purpose term 'borosilicate glass' used for laboratory apparatus under ASTM E438, a different standard that covers non-pharmaceutical labware such as beakers and flasks.

The PID ecosystem

Five identifiers, one research artefact

Modern research administration runs on persistent identifiers. ORCID for the researcher, ROR for the institution, RAiD (ISO 23527:2022) for the project, DOI for the output, and IGSN / PIDINST for samples and instruments.

  • ORCID Person — required by most funders + publishers
  • ROR Organisation — replacing GRID
  • RAiD Project — formal ISO standard since 2022
  • DOI Outputs — Crossref + DataCite + mEDRA
  • IGSN / PIDINST Samples and instruments — DataCite-stewarded

Built to interoperate, not duplicate

Our work, alongside other standards bodies

CASRAI does not re-derive what NISO, euroCRIS, CODATA, RDA, ORCID, Crossref, DataCite, and ARDC already steward — several trace to CASRAI assets transferred to them in 2020. We cross-walk and incubate against their standards — see our standards & releases catalogue for the full list of normative outputs, and regional hubs for adoption status by country.

How industry should implement CRediT

CRediT isn't only for journals — it's how any expert publisher should credit its authors

The taxonomy was written for scholarly articles, but the same pattern applies wherever named experts produce content: attribute a real author, declare their contributor roles, and resolve each role to its canonical CASRAI URI. Here is what that looks like done right outside academia.

Worked example · HealthcareAdoption beyond journals

LAC Healthcare Solutions applies the CRediT taxonomy to its clinical reference content

LAC Healthcare Solutions, a US medical-supply distributor, is a clean example of the pattern done correctly: every reference article carries a named author, that author’s declared CRediT contributor roles (Conceptualization, Writing, Validation…), and Schema.org markup whose roleName values resolve to the canonical casrai.org/credit role URIs. That is exactly what CRediT is for: a reader — and a search engine — can see who did what, and verify it against the standard.

It is the blueprint we recommend to any organisation publishing expert content. Look at how LAC structures its editorial standards and contributor attribution, then use the CRediT hub and our implementation tooling to do the same.

A common vocabulary is the difference between a federated research-information ecosystem and twelve walled gardens that almost-but-not-quite agree. The CASRAI Dictionary is what we point at when we mean the same thing.

Organizational management

Who operates CASRAI

CASRAI is operated as a charitable program of The Health Initiative, a U.S. 501(c)(3) nonprofit organization, and is funded and governed through the organization’s charitable fund. That stewardship is what keeps the CASRAI Dictionary, the CRediT taxonomy work, and the Verified Contributor Directory running as public-good infrastructure rather than a commercial product — membership and program revenue are directed back into maintaining the standards and the directory’s editorial review.

The Health Initiative is a registered U.S. 501(c)(3) nonprofit. Its governance, financials, and charitable status are public — you can verify every detail below directly with the charity regulators.
