Scope

Claims stay smaller than the picture.

The exhibit is deliberately specific about what comes from a source, what the simulator chooses, and what exists only to make a difficult mechanism teachable.

The mechanism is real enough to inspect: separate systems know different things, a routed transaction crosses explicit trust and meaning boundaries, failures stop before the wrong commit, and recovery leaves evidence. The services, people, payloads, credentials, times, policies, and results are not real.

“Accepted” means only that a synthetic artifact passed this toy’s authored checks. It does not mean medically correct, clinically appropriate, secure, lawful, interoperable at scale, or safe for care.

specified

Specified

A claim directly supported by the cited primary specification.

implementation choice

Implementation choice

One bounded way this simulator realizes a capability the source leaves variable.

pedagogical extension

Pedagogical extension

An authored teaching device, named as such and never attributed to the standard.

Architecture doctrine

A governed journey, not one enormous database.

The map describes responsibilities and contracts. It does not prescribe a server count, product list, or national deployment topology.

Shown

Logical architecture

Capabilities, authority boundaries, dependencies, and the messages that cross between them.

  • One logical component can be supplied by many products.
  • One product can supply several logical components.
  • Only services invoked by the active transaction illuminate.

Not shown

Physical architecture

Hosts, zones, databases, queues, networks, regions, operators, and vendor products.

  • No box means “one server.”
  • No route demonstrates encryption or availability.
  • No layout is a deployment recommendation.

The orientation mnemonic

Different questions, different authorities.

Who pays
Finance and Insurance Service

The Interoperability Layer coordinates those answers without becoming authoritative for any of them.

A

Reference and master data

Client, facility, worker, product, and terminology services govern stable reference facts.

B

Semantic mapping

A Terminology Service validates codes and supplies a versioned relationship between meanings.

C

Structural transformation

An IOL mediator creates a new wire shape, preserving and linking the immutable source artifact.

There is no generic canonical OpenHIE component called “the reference and translation service.” A mediator may apply a mapping obtained from a Terminology Service; it may not invent clinical equivalence. When a component is outside the active route, the exhibit says Not invoked in this transaction.

Component/source map

Every service owns less than the whole.

All rows use the architecture exports that drive the exhibit. OpenHIE sources are published 5.2; every source was accessed 10 August 2026.

Evidence and policy

Four records, four different questions.

A routing trace, a security event, derivation evidence, and a consent directive overlap—but they are not interchangeable.

01 · route

Transaction trace

Where did the request go?

Envelope references, route hops, attempts, status, response, error boundary, and replay relationship.

Inspired partly by OpenHIM transaction inspection; not an audit standard.

02 · security

AuditEvent-like evidence

What did a system do or attempt?

Action, outcome, purpose, actors, source, and affected artifact reference—without raw clinical values or credentials.

FHIR R4 AuditEvent is Trial Use, FMM 3.

03 · lineage

Provenance-like evidence

How did this artifact come to be?

Version-specific target, activity, source entity, author or performer, facility, transformer, and mapping version.

FHIR R4 Provenance is Trial Use, FMM 3.

04 · directive

Consent and policy input

What choice constrains a governed action?

A directive can express permission or denial for actors, purposes, actions, and periods. A policy engine must still evaluate and enforce it.

FHIR R4 Consent is Trial Use, FMM 2; only privacy is modeled in R4.
Audit is evidence, not prevention.

Transport protection, authentication, authorization, least privilege, policy enforcement, integrity, availability, audit, and provenance remain distinct. A successful technical check does not certify good care or clinical appropriateness.

Standards and profiles

A reference is not a conformance claim.

The OpenHIE release, current IHE profile publications, and permanent FHIR R4 pages have separate versions and maturity states.

Payload honesty

The wire specimens are illustrative demo artifacts.

demo-clinic-v1, demo-exchange-envelope-v1, and demo-canonical-v1 are local teaching schemas. A pretty JSON fragment is not valid FHIR. The published OpenHIE SHR workflows describe XDS.b/CDA and PIX/CSD, with MHD optional; real exchanges may also use FHIR, HL7 v2, CDA/XDS, and other governed standards.

One possible technology

OpenHIM is not OpenHIE.

OpenHIM describes itself as one reference implementation of the OpenHIE interoperability-layer role. It is not required, not embedded here, and not the runtime behind this simulation. Its rerun documentation explicitly warns about duplicate downstream data; this toy’s idempotency behavior is its own.

The one sourced concept

LOINC 718-7

The only real terminology concept displayed is 718-7, Hemoglobin [Mass/volume] in Blood. It is active; its fully specified name is Hemoglobin:MCnc:Pt:Bld:Qn: and its example units include g/dL and g/L. The code does not establish a unit conversion, reference range, interpretation, or clinical correctness. The exhibit ships no LOINC distribution.

Synthetic-data manifest

Every name and identifier is invented.

Fixtures are committed, deterministic, ephemeral, and visually marked. Reserved domains and synthetic namespaces make the boundary inspectable.

Visible synthetic entities, namespaces, and forbidden boundaries

Exchange identifiersSYN- prefixed or urn:synthetic: message, trace, correlation, artifact, mapping, and provenance identifiersDeterministic authored values; never user identifiers and never serialized clinical payloads in URLs.
System addressesDisplayed endpoints under example.org and email under .invalidPresentation-only reserved domains; the application never calls them.
Time and scenariosFixed demonstration timestamps, named presets, numeric seed, and authored failure slugsLogical time advances only through discrete events; refresh restores the fixture.
Aggregate and operationsIdentifier-stripped contribution, one periodic count, retry/dead-letter entries, redacted audit events, and provenance recordsAggregate output has no patient drill-through but is not described as automatically anonymous.

Accepted input

Only authored buttons, scenario IDs, lens choices, and a numeric seed.

No paste field, upload, camera, microphone, clipboard import, free-form patient field, or external API.

Retention

Simulation state lives in memory and refresh resets it.

Payloads, traces, identifiers, and clinical values are not stored in cookies or browser persistence.

Downloads and URLs

Trace filenames and wrappers say SYNTHETIC-NOT-FOR-CLINICAL-USE.

URLs contain only allow-listed authored IDs, a lens, or a numeric seed—never demographics or payload JSON.

Accessibility and privacy

Readable first; interactive second.

The Method route is complete server-rendered content. Its only interactions are ordinary links and native disclosure controls.

Semantic reading order

One page heading, ordered sections, native tables with captions, descriptive links, lists, and definition lists remain useful without JavaScript.

Keyboard and touch

No custom gestures or pointer-only disclosures. Links and native details controls use visible focus treatment and generous targets.

Responsive and printable

Tables become labeled row blocks on narrow screens; content does not depend on a shrunken diagram. Print removes chrome and preserves source URLs.

No runtime network

No backend, analytics, tracker, cookie, remote asset, authentication service, service worker, or runtime data request. Source links navigate only when a visitor chooses them.

Population-data caution

Aggregate does not mean anonymous.

Removing direct identifiers is necessary but insufficient. A very small count can reveal information when the population is known or when it can be linked with other data. The HMIS view therefore keeps a visible small-cell warning and makes no anonymity claim.

Assumptions

The choices that hold the toy together.

These assumptions are explicit so a changed source, policy, or implementation goal has a visible place to alter the model.

  1. A01

    The unprefixed OpenHIE documentation root is the published 5.2-en branch; staging and development pages are deliberately excluded.

  2. A02

    Each box represents a logical capability. One product may provide several capabilities, or one capability may be distributed across several products.

  3. A03

    The authored policy evaluator is a transparent teaching device, not a canonical OpenHIE consent component or a jurisdictional rule set.

  4. A04

    The local LUM-HB mapping is curated for this single demonstration context; the display text alone is not treated as proof of equivalence.

  5. A05

    Current IHE profile publications are cited separately from the August 2024 OpenHIE release and do not retroactively change that release.

  6. A06

    The demo schemas are illustrative. Until named validator checks exist and pass, any FHIR-like JSON remains FHIR-shaped rather than valid FHIR.

  7. A07

    Replay safety is supplied by deterministic toy idempotency rules; neither OpenHIM nor the cited specifications provide an exactly-once guarantee.

  8. A08

    Only authored transactions can run. Free-form integration, uploaded records, and arbitrary endpoint calls are outside the model.

Limitations

What cannot be inferred from a successful run.

A deterministic miniature is useful precisely because it leaves most real-world complexity outside the frame.

  1. L01

    This exhibit cannot demonstrate production security, transport encryption, identity proofing, key management, authorization enforcement, or incident response.

  2. L02

    It cannot establish legal consent, privacy compliance, data-sovereignty compliance, clinical safety, clinical correctness, or medical appropriateness.

  3. L03

    Identity matching uses fixed outcomes, not a validated algorithm, population-scale tuning, or a real adjudication operation.

  4. L04

    Terminology is reduced to one sourced LOINC target and a tiny fictional local code set; it does not demonstrate licensing, release management, or terminology-server scale.

  5. L05

    The SHR behavior omits durable persistence, broad clinical content, full document sharing, concurrency, reconciliation, availability, and disaster recovery.

  6. L06

    The IOL behavior omits real network transport, durable queues, message-retention policy, operational staffing, and performance under load.

  7. L07

    LMIS stock behavior and the exact Product Catalogue transaction are pedagogical because OpenHIE 5.2 leaves their detailed workflow requirements undetermined.

  8. L08

    Aggregate data may still disclose information through a small cell or linkage with other data. Removing direct identifiers is not anonymization.

  9. L09

    Audit evidence is ephemeral and redacted; it is not an immutable ledger, a tamperproof repository, or proof that a harmful action was prevented.

  10. L10

    Referencing FHIR and IHE material does not mean the payloads or actors conform to those standards or profiles.
