OIML SMART, the program

The first program built on the Primmel SMART platform: OIML International Recommendations as executable models, the OIML Certification System as a digital workflow, and a classroom to learn all of it. Two tiers, SMART (Type-approval) and SMART+ (instrument-instance lifecycle).

§ 00Two tiers, one programSMART · SMART+

SMART covers the published, expert-authored artifacts (Recommendations, Vocabulary, Resources), the SMART Studio reader (the interactive, read-only view over a Recommendation's model), CNML at the Issuing-Authority / Type-approval level, and the two platform deployments that run the Type-approval workflow: the global OIML-CS SMART Platform and the optional member-state OIML SMART Platform.

SMART+ extends the program to the full instrument-instance and measurement lifecycle: CNML at the Type-instance and measurement level, the SMART Measuring Instruments family and the SMI Simulation, and the OIML-CS SMART+ Platform (global) and OIML SMART+ Platform (member-state) that run it.

§ 01The Recommendations4 modelled

Each Recommendation is a Primmel package, requirements, conformance tests, and report forms modelled as constraints, processes, and evidence interfaces over the instrument's aspects, with clause-level provenance back to the source document.

§ 02The certification workflowOIML-CS · B 18:2025

The OIML Certification System is modelled end to end, application, test dispatch, laboratory testing, type evaluation, certificate issuance, on the ISO/IEC 17000-series conformity assessment chain it normatively references. Every participant role, every document, every verdict is an entity in the model.

The OIML-CS workflow chain: application through testing, evaluation, and certificate issuance
§ 03The SMI SimulationSST · no hardware needed

The program ships Simulated SMART Measuring Instrument Twins (SSTs) of real instrument families, analog and digital load cells, belt scales, gas meters, with configurable physics: temperature cycles leave realistic residuals, creep and hysteresis behave the way the Recommendation says they should. The demo manual walks the full chain against an SST: certify a load cell from application to certificate without touching hardware.

§ 04The classroomtiers 0–4

A layered curriculum: each tier is complete for its depth, and each opens into the next. Stop wherever your role stops.

Tier 0

the tour

, fifteen minutes: what a SMART Recommendation is, why it exists, what it changes.
Tier 1

the reader

, read a modelled Recommendation, requirements, tests, forms, and find your way around.
Tier 2

the operator

, run the certification chain against the simulator: apply, test, evaluate, issue.
Tier 3

the author

, model a Recommendation yourself, in Primmel, from the source PDF to the package.
Tier 4

the platform

, extend the kernel, the runtime, and the twin interfaces, the internals, proved.

The full curriculum lives in the classroom volume.
