prior version: https://w3id.org/sstim/0.8.0
version IRI: https://w3id.org/sstim/0.9.0
version info: 0.9.0
history note: v0.1.0 (2026-04): Initial public release. Vocabulary seeded from BSC preset catalog v0.9.1. Term 'Sensory Stimulation' adopted as the established umbrella over the coined term 'Sensory Harnessing'.
history note: v0.2.0 (2026-06): Added sstim:CautionTag, sstim:VoiceType, and sstim:PermutationFunction classification classes and the sstim:hasCautionTag property; dual-typed the caution, voice-type, permutation, and stimulus-temporal-structure SKOS concepts; added the StimulusTemporalStructure concept scheme; completed it/pt/es prefLabel coverage across the vocabulary; added external upper-ontology label stubs. Backward-compatible minor release (no terms removed or renamed).
history note: v0.2.0 erratum (2026-06): Corrected external alignment IRIs that had been wrong since 0.1.0: every Wikidata QID (all resolved to unrelated entities), the EvidenceClaim parent (iao:0000001 'conditional specification' → iao:0000030 'information content entity'), the obsolete OBI planned-process parent (added cob:0000082), a non-existent ORCID (replaced with the verified ORCID 0000-0002-9699-629X), and a dead repository link. No vocabulary terms changed.
history note: v0.3.0 (2026-06): Added sstim-v:TechniqueScheme — a vendor-neutral controlled vocabulary of auditory and cross-modal sensory stimulation techniques — together with seven new StimulationMechanism concepts (ASSR, auditory-motor coupling, closed-loop phase reinforcement, masking, vibrotactile mechanoreception, acoustic startle, ultrasonic neuromodulation) and the sstim:techniqueModality property. Two non-evidence-bearing folk techniques are catalogued and explicitly flagged via skos:editorialNote. Additive, backward-compatible release (no terms removed or renamed).
history note: v0.5.0 (2026-07): Domain-content coverage (P5) and evidence-integrity governance (P7). Added visual, tactile, and cross-modal techniques with the steady-state evoked-potential mechanism family (SSVEP, SSSEP, multisensory integration) (ADR 0015); reference-pitch retuning with the carrier-vs-modulation evidence firewall (ADR 0017); the modality-nomenclature cleanup — the somatosensory/haptic/tactile/vibrotactile convention and the sstim-v: to sstim-ex: perceived-modality closeMatch bridge (ADR 0019); visual/tactile/multisensory evidence-modality tags (VIS, TACTILE, MULTISENSORY); the C0-C5 public-claim-level taxonomy with SHACL claim-legality and the conditional-citation constraint (ADR 0018); and the first populated technique EvidenceClaim instances (P5.4, instance data). Version 0.4.0 was the standalone exposure / Sensory Field module release (ADR 0010, 0011). Additive, backward-compatible (no terms removed or renamed).
history note: v0.6.0 (2026-07): Semantic-quality release. Controlled vocabulary categories are modeled consistently as information content entities; session specifications are PROV plans and session instances are stimulation interventions; self-reports support explicit collection phases; caution tags carry machine-readable severity and action metadata; scalar cardinalities, definitions, evidence provenance, and integrity constraints are strengthened. An external automated audit removed the obsolete OBI planned-process superclass, narrowed the technique upper alignment, completed FAIR metadata, and corrected safety-source attribution. The maintainer guided and accepted the release review; independent human ontology review is deferred. See ADR 0021, ADR 0022, and the 2026-07-10 external automated review report.
history note: v0.7.0 (2026-07): Evidence and ecosystem governance release. ADR 0027 replaces overloaded evidence claims with immutable assessment revisions, atomic bounded propositions, qualified evidence bases, explicit scope axes, source/search governance, and PROV review decisions while retaining deprecated compatibility terms. ADRs 0024 and 0031 add the neutral EcosystemAgent module, qualified relationships and memberships, implementation responsibility, purpose-scoped admission activities, a closed public projection, and separate access-controlled audit shapes. Public fixtures are synthetic; real live-only ecosystem records remain outside the Zenodo-tracked release repository.
history note: v0.9.0 (2026-07): Stimulation and neuromodulation release (ADR 0034). Adds a neutral sstim:Stimulation umbrella and sstim:Neuromodulation sibling at the process, intervention, technique, and protocol layers, with the overlap named at each layer as a defined intersection class requiring an intended canonical sensory-transduction route: neither family subsumes the other. Adds five orthogonal facet axes — neural access route, delivery approach, neural target site, neural system, and neural phenomenon — kept separate because a route, a dynamic, a system, and an outcome domain are not values on one scale, and reused across intended, proposed-mechanism, and observed-outcome roles by distinct properties. Shared domains and ranges widen to the neutral parents so a non-sensory technique can be the subject of a conformant evidence assessment. Retypes focused-ultrasound neuromodulation off the sensory hierarchy and redefines it by its intended focused neural target rather than by absence of an audible percept; deprecates five response-as-mechanism entries (FFR, ASSR, SSVEP, SSSEP, acoustic startle) in favour of typed neural-phenomenon concepts, removing their mechanism typing and scheme topology rather than deprecating alone. Relabels TechniqueScheme, whose IRI was never sensory-scoped. Catalogues a six-technique non-sensory contrast set (rTMS, tDCS, tACS, DBS, VNS, targeted intrathecal delivery) so the route axis is exercised; none is referenced by any BSC preset, framework, protocol, or implementation, and inclusion asserts neither capability nor efficacy nor safety. Replaces the SHACL escape hatch in which any skos:editorialNote suppressed structural requirements with composed, disjointly-targeted shapes. Breaking on mutable latest for consumers of the retyped focused-ultrasound entry and the five deprecated mechanism IRIs; frozen 0.3.0-0.8.0 snapshots retain their published entailments.
status: released

Assessment Proposition
type: Class
subclass of: IAO_0000030
definition: One immutable, atomic, independently assessable proposition evaluated by an evidence assessment: exactly one subject, one outcome concept, one scope, one proposition form, and exact text or digest.

Assessment Scope
type: Class
subclass of: IAO_0000030
definition: The explicit modality, population/model, intervention/context, and comparator scope of an assessment proposition. Every axis carries a named value or an explicit unknown / not-reported / not-applicable marker; omission never means universal applicability.

Bibliographic Reference
type: Class
subclass of: IAO_0000030
definition: A bibliographic record of a published source. Being recorded implies neither endorsement nor permission to quote, reproduce, or display the source.

Binaural Voice
type: Class
subclass of: Voice
definition: Two sine tones at slightly different frequencies (fl, fr) presented dichotically to produce a perceived beat at |fr - fl| Hz.

Canonical Sensory Transduction Access Route
type: Class
subclass of: Neural Access Route
definition: A neural access route that engages canonical sensory receptor transduction and afferent processing. This is the route value that distinguishes the sensory-route neuromodulation overlap from approaches that bypass canonical sensory transduction.

Caution Severity
type: Class
subclass of: IAO_0000030
definition: A controlled ordinal category for prioritizing a caution tag in user interfaces and validation. Severity describes the response required by the application; it is not a clinical diagnosis or risk probability.

Caution Tag
type: Class
label: Etichetta di Cautela @it
label: Etiqueta de Cautela @pt
label: Etiqueta de Precaución @es
subclass of: IAO_0000030
definition: A safety or usage advisory flag attached to a preset, signalling conditions under which the preset may be unsuitable (e.g. photosensitivity risk, drowsiness, high sensory intensity). Advisory wellness metadata, not a medical contraindication.

Claim Direction
type: Class
subclass of: IAO_0000030
definition: Whether a body of evidence supports, is mixed on, is inconclusive about, or refutes the asserted relation.

Comparator Descriptor
type: Class
subclass of: IAO_0000030
definition: An identified description of the comparison condition (for example sham, no-stimulus, baseline, or alternative frequency) referenced by an assessment scope or evidence basis.

Conflict Disclosure
type: Class
subclass of: IAO_0000030
definition: A record of declared conflicts of interest for a review, including the explicit declaration that no conflict was declared.

Effect Direction
type: Class
subclass of: IAO_0000030
definition: The direction of the measured outcome (increase, decrease, or no change). Wellness-neutral; describes what was measured, not a health claim.

Entrainment-Based Technique
type: Class
subclass of: Sensory Stimulation Technique
disjoint with: Non-Entrainment Technique
definition: A Sensory Stimulation technique whose primary proposed mechanism involves frequency-following responses, phase-locking, or oscillatory coupling between a periodic stimulus and endogenous neural oscillations.
example: Binaural beat stimulation, isochronous tone stimulation, photic driving, Symmetry permutation entrainment.

Evidence Assessment Activity
type: Class
subclass of: Activity
definition: The PROV activity that generates an evidence assessment revision. It used every qualified basis, its sources, and the immutable rubric/method revision actually applied, and carries a qualified association naming the responsible agent and role.

Evidence Assessment Claim
type: Class
subclass of: Evidence Claim
definition: A versioned, immutable assessment of an identified evidence basis about one atomic bounded proposition. The sole concrete evidence-bearing class: exactly one evidence tier and one claim direction, at least one qualified evidence basis, and exactly one assessed proposition. A correction mints a new revision IRI linked with prov:wasRevisionOf; it never edits a published revision in place.

Evidence Basis
type: Class
subclass of: IAO_0000030
definition: One qualified contribution of a single source to an evidence assessment, carrying source-level modality, intervention, study design, model/population, synthesis, and observed-result metadata separately from the assessment's own conclusion.

Evidence Claim
type: Class
subclass of: IAO_0000030
definition: Compatibility superclass of evidence assessments. Direct instantiation is rejected by SHACL: every instance must carry a concrete evidence subtype (sstim:EvidenceAssessmentClaim). Hypotheses, research questions, boundary applicability, requirements, design objectives, planned outcomes, knowledge-status assertions, and session observations are never EvidenceClaims.
history note: Narrowed 2026-07-13 (ADR 0027) from a single overloaded claim class to the compatibility superclass of EvidenceAssessmentClaim.

Evidence Modality Tag (deprecated)
type: Class
subclass of: IAO_0000030
deprecated: true
definition: Deprecated ADR 0027: the tag conflated sensory modality (AUD, AV, VIS, TACTILE, MULTISENSORY), intervention (BREATH), study model (PRECLINICAL), and synthesis type (REVIEW). Authoritative data uses the orthogonal basis axes; the class survives only for the generated non-authoritative 0.7 compatibility view and is removed no earlier than 1.0.

Evidence Outcome Concept
type: Class
subclass of: IAO_0000030
definition: A controlled endpoint, response, or mechanism category used to identify what a proposition or reported source result is about. It is a category, not an observed result or benefit.

Evidence Proposition Form
type: Class
subclass of: IAO_0000030
definition: The logical form of an assessment proposition: bounded relation, bounded null result, scoped search finding, or universal absence. Universal-absence propositions never conform; a scoped search finding requires an evidence search record basis.

Evidence Review Activity
type: Class
subclass of: Activity
definition: The PROV activity that reviews exactly one assessment revision under a named rubric/policy revision and generates an immutable evidence review decision.

Evidence Review Decision
type: Class
subclass of: IAO_0000030
definition: An immutable review decision about one assessment revision: reviewer relationship, independence determination, and decision are independent axes. A later decision supersedes or invalidates the earlier one; no mutable effective-review pointer exists.

Evidence Search Activity
type: Class
subclass of: Activity
definition: The PROV activity that executes an evidence search and generates an immutable evidence search record, with execution times and a qualified responsible agent/role.

Evidence Search Record
type: Class
subclass of: IAO_0000030
definition: An immutable, reproducible record of a literature/evidence search: sources, exact query, coverage dates, eligibility criteria, result count, and content digest. Supports only scoped 'no eligible evidence found' findings, never universal absence.

Evidence Synthesis Type
type: Class
subclass of: IAO_0000030
definition: The synthesis level of an evidence source: primary study, narrative review, systematic review, meta-analysis, literature review, or tutorial. A narrative review does not acquire systematic-review status merely because it synthesizes literature.

Evidence Tier Value
type: Class
subclass of: IAO_0000030
definition: A classification of empirical support strength for a specific stimulation claim, accounting for study quality, result consistency, modality match, and population match. Six tiers: speculative(1) through established(6). A tier is meaningful only together with the claim direction and the bounded proposition scope it was assigned to.

Frequency Band
type: Class
label: Banda de Frecuencia @es
label: Banda de Frequência @pt
label: Banda di Frequenza @it
subclass of: IAO_0000030
definition: An information entity describing a named Hz range used in BSC protocol design for targeting and evidence classification. BSC operational design category — not a medical diagnostic taxonomy or universal EEG ontology.

Frequency Band Group
type: Class
label: Grupo de Bandas de Frecuencia @es
label: Grupo de Bandas de Frequência @pt
label: Gruppo di Bande di Frequenza @it
subclass of: IAO_0000030
definition: A named collection of frequency bands used as a SKOS scheme root or aggregate grouping concept. Not a band with a specific Hz range; used for SKOS hierarchy navigation (skos:narrower* traversal) rather than for range arithmetic.

Governed Research Output
type: Class
subclass of: Entity
definition: A versioned study record, dataset revision, or analysis output admitted as an evidence source. Requires exactly one source-governance record; an ungoverned dataset cannot serve as an evidence basis source.

Independence Determination
type: Class
subclass of: IAO_0000030
definition: A policy-based determination of reviewer independence: independent, not independent, or undetermined. An independent or not-independent determination requires a named independence policy and conflict disclosure.

Intended Effect
type: Class
subclass of: IAO_0000030
definition: A controlled information category identifying a target change in physiological, psychological, or cognitive state that a sensory stimulation intervention is designed to facilitate. It records design intent, not a guaranteed outcome.

Martigli-Binaural Voice
type: Class
subclass of: Voice
definition: Binaural beat combined with Martigli breathing oscillation. Both carriers sweep in parallel, maintaining constant beat frequency while timbral register evolves with breathing.

Martigli Voice
type: Class
subclass of: Voice
definition: A single tone whose frequency oscillates sinusoidally with a breathing arc that decelerates linearly from mp0 to mp1 over md seconds.

Modality Applicability
type: Class
subclass of: IAO_0000030
definition: A controlled statement of how sensory modality applies to an evidence source: mixed modalities, unknown/not reported, or not applicable. Distinct states, never a wildcard.

Neural Access Route
type: Class
subclass of: IAO_0000030
definition: A controlled category for the biological route through which a stimulation process is intended to engage a neural target. Route values describe the declared intended route; a competing or demonstrated actual mechanism remains an evidence-qualified statement recorded on a mechanism or outcome concept.
scope note: 'Receptor' on this axis means a canonical sensory receptor, never a molecular drug receptor. Mixed access is represented by multiple route values, which is not the same as uncertainty; an unresolved route is an epistemic status recorded by a scoped knowledge-status assertion, not a pseudo-route.

Neural Phenomenon
type: Class
subclass of: IAO_0000030
definition: A controlled information category for a coherent functional neural phenomenon, such as excitability or firing, oscillatory dynamics, temporal coordination, synaptic transmission, neurochemical signaling, connectivity or plasticity, and autonomic neural regulation.
scope note: One value set is reused across proposed-mechanism, intended-target, and observed-outcome roles, which are kept distinct by three separate properties. This axis replaces any single 'target level' axis: a route, a dynamic, a system, and an outcome domain are not values on one scale.

Neural System
type: Class
subclass of: IAO_0000030
definition: A controlled information category for a distributed organizational neural system — sensory, motor, autonomic, or a named sensory subsystem. This is the axis for neuromodulation of a sensory system; it does not imply that the intervention entered through that sensory system.

Neural Target Site
type: Class
subclass of: IAO_0000030
definition: A controlled information category for a broad anatomical target of a stimulation process, such as brain, cortex, deep-brain structure, spinal cord, peripheral nerve, or cranial nerve. It is a classification category, not the anatomical entity itself.
scope note: A local target category may have more than one broader concept; no forced single-parent tree is required. External anatomy alignment is a separate, evidence-checked pass.

Neuromodulation
type: Class
label: Neuromodulación @es
label: Neuromodulazione @it
label: Neuromodulação @pt
subclass of: Stimulation
definition: In SSTIM, a deliberately applied stimulation process whose declared intervention objective is to alter activity or function at an identified neural target. Anatomical site and distributed neural system are recorded on separate facets. Membership records target and design intent; whether modulation occurred is represented separately through observations and evidence.
scope note: This intervention-side class excludes endogenous physiological neuromodulation and stimulation performed solely to probe or measure a response without a neural-modulation objective. It does not mean treatment or successful modulation. It neither subsumes nor is subsumed by sstim:SensoryStimulation; the two overlap, and the overlap is named by sstim:SensoryRouteNeuromodulation (ADR 0034).

Neuromodulation Intervention
type: Class
subclass of: Neuromodulation
subclass of: Stimulation Intervention
definition: A specific, designed execution of a neuromodulation process, with a declared neural access route, delivery approach, and intended neural target. Membership does not assert successful modulation, benefit, or safety.

Neuromodulation Protocol
type: Class
subclass of: Stimulation Protocol
definition: A protocol whose planned objective is to alter activity or function at an identified neural target. It remains an information artifact: a protocol records the planned objective through this type plus its route and target facets, while the realized process is typed as an intervention.

Neuromodulation Technique
type: Class
label: Tecnica di Neuromodulazione @it
label: Técnica de Neuromodulación @es
label: Técnica de Neuromodulação @pt
subclass of: Stimulation Technique
definition: A stimulation technique whose defining intervention objective is to alter activity or function at an identified neural target, with anatomical site and distributed neural system recorded separately. Membership does not assert successful modulation, benefit, or safety.
scope note: Cataloguing a neuromodulation technique states that SSTIM can describe it, not that BSC Lab delivers it or that it is effective. A proposed neural mechanism or an evoked response is not by itself a neuromodulation objective (ADR 0034 §2).

Non-Entrainment Technique
type: Class
subclass of: Sensory Stimulation Technique
definition: A Sensory Stimulation technique whose proposed mechanism does not rely on frequency-following responses. Includes stochastic resonance, autonomic respiratory entrainment, and attentional anchoring via ambient structured sound.
example: Calibrated pink noise for stochastic resonance, Martigli breathing oscillation, ambient Symmetry sequences for attentional anchoring.

Permutation Function
type: Class
subclass of: IAO_0000030
definition: A named reordering rule applied to a Symmetry voice note sequence at each cycle boundary (identity, rotate forward, rotate backward, reversal, shuffle).

Population Descriptor
type: Class
subclass of: IAO_0000030
definition: An identified description of a study population or participant group referenced by an assessment scope or evidence basis.

Preset
type: Class
subclass of: IAO_0000030
definition: A reusable, versioned parameter configuration for a sensory stimulation implementation, specifying audio architecture, target frequency bands, evidence grounding, safety metadata, and multilingual content for a possible session. A preset follows a protocol or framework but is not itself the protocol.

Preset Group
type: Class
subclass of: IAO_0000030
definition: A classification of BSC presets by design character, evidence strength, and use context. Five groups: Heal, Support, Perform, Indulge, Transcend.

Public Claim Level
type: Class
label: Livello di Affermazione Pubblica @it
label: Nivel de Afirmación Pública @es
label: Nível de Alegação Pública @pt
subclass of: IAO_0000030
definition: A named ceiling on what a sensory-stimulation product may assert about itself on a public-facing surface, ordered from descriptive fact to quantified/superiority claims. Each level carries the minimum evidence-tier rank required to assert at that level publicly, so over-claiming is machine-checkable. A risk-reduction classification, not legal advice.

Public-Safe Reference
type: Class
subclass of: Bibliographic Reference
definition: A peer-reviewed publication cleared for citation in BSC user-facing content. Must be cleared in the BSC Reference Agent before use in preset techDesc fields.

Review Decision Value
type: Class
subclass of: IAO_0000030
definition: The outcome of an evidence review: confirm, request revision, or reject.

Review Status
type: Class
subclass of: IAO_0000030
definition: The audit status of an evidence claim's tier assignment (provisional, reviewed, or needs update).

Reviewer Relationship
type: Class
subclass of: IAO_0000030
definition: The relationship of a review's agent to the assessed work: self, same organization, external, or unknown. External relationship never implies independence.

Scope Marker
type: Class
subclass of: IAO_0000030
definition: A controlled marker stating that a scope axis is unknown, not reported, or not applicable. Mutually exclusive with concrete values on the same axis.

Self-Report
type: Class
subclass of: IAO_0000030
definition: A consent-governed, session-associated self-assessment capturing subjective affect, focus, sleepiness, quality, and optional free text at an explicitly identified collection phase.

Self-Report Phase
type: Class
subclass of: IAO_0000030
definition: A controlled category identifying when a self-report was collected relative to its associated session, such as before, immediately after, or at follow-up.

Sensory Modality
type: Class
label: Modalidad Sensorial @es
label: Modalidade Sensorial @pt
label: Modalità Sensoriale @it
subclass of: IAO_0000030
definition: A controlled information category identifying a channel of sensory perception through which stimulation is delivered or perceived. Values include auditory, visual, somatosensory, interoceptive, vestibular, and olfactory.

Sensory-Route Neuromodulation
type: Class
label: Neuromodulación por Vía Sensorial @es
label: Neuromodulazione per Via Sensoriale @it
label: Neuromodulação por Via Sensorial @pt
subclass of: Neuromodulation
subclass of: Sensory Stimulation
equivalent class: Class
  intersection of: Neuromodulation
  intersection of: Sensory Stimulation
  intersection of: Restriction
    on property: neural access route
    some values from: Canonical Sensory Transduction Access Route
definition: A stimulation process that is both sensory stimulation and neuromodulation, and that declares canonical sensory transduction and afferent processing as an intended causal route. This is the overlap of the two families, not a subclass of either alone.
scope note: Distinct from neuromodulation of a sensory system, which is a target-axis statement, and from a sensation merely accompanying neuromodulation, which is recorded through perceived modality and channel role (ADR 0034 §2).

Sensory-Route Neuromodulation Intervention
type: Class
subclass of: Neuromodulation Intervention
subclass of: Sensory Stimulation Intervention
equivalent class: Class
  intersection of: Neuromodulation Intervention
  intersection of: Sensory Stimulation Intervention
  intersection of: Restriction
    on property: neural access route
    some values from: Canonical Sensory Transduction Access Route
definition: A planned or executed intervention that is both a sensory stimulation intervention and a neuromodulation intervention, declaring canonical sensory transduction and afferent processing as an intended causal route.

Sensory-Route Neuromodulation Protocol
type: Class
subclass of: Neuromodulation Protocol
subclass of: Sensory Stimulation Protocol
equivalent class: Class
  intersection of: Neuromodulation Protocol
  intersection of: Sensory Stimulation Protocol
  intersection of: Restriction
    on property: neural access route
    some values from: Canonical Sensory Transduction Access Route
definition: A protocol that is both a sensory stimulation protocol and a neuromodulation protocol, declaring canonical sensory transduction and afferent processing as an intended causal route.

Sensory-Route Neuromodulation Technique
type: Class
subclass of: Neuromodulation Technique
subclass of: Sensory Stimulation Technique
equivalent class: Class
  intersection of: Neuromodulation Technique
  intersection of: Sensory Stimulation Technique
  intersection of: Restriction
    on property: neural access route
    some values from: Canonical Sensory Transduction Access Route
definition: A technique that is both a sensory stimulation technique and a neuromodulation technique, declaring canonical sensory transduction and afferent processing as an intended causal route. A technique is dual-typed here only when neural-modulation intent is part of the technique concept's own definition, never because one possible use is neuromodulatory.

Sensory Stimulation
type: Class
label: Estimulación Sensorial @es
label: Estimulação Sensorial @pt
label: Stimolazione Sensoriale @it
subclass of: BFO_0000015
subclass of: Stimulation
definition: A stimulation process whose defining intervention route engages canonical sensory transduction and afferent processing with structured input delivered according to specified parameters for a declared purpose. The class identifies the delivery process; any mechanism, response, or outcome is represented separately and requires its own evidence.
scope note: Conscious perception is not required, and an incidental sensation arising from another primary route is insufficient. Covers entrainment-based stimulation (binaural beats, isochronous tones), non-entrainment stimulation (stochastic resonance, attentional anchoring), and autonomic stimulation (paced respiratory entrainment). Does not include passive incidental sensory exposure.

Sensory Stimulation Framework
type: Class
subclass of: IAO_0000030
definition: A broad information artifact defining a family of sensory stimulation principles, techniques, protocols, evidence rules, grouping logic, and design constraints. A framework can guide multiple protocols, implementations, presets, and sessions.

Sensory Stimulation Implementation
type: Class
subclass of: Entity
definition: A concrete realization of a sensory stimulation framework or protocol, represented in SSTIM by the implementation identity and metadata. An implementation can be software, hardware, mechanical, manual, or hybrid.

Sensory Stimulation Intervention
type: Class
label: Intervención de Estimulación Sensorial @es
label: Intervento di Stimolazione Sensoriale @it
label: Intervenção de Estimulação Sensorial @pt
subclass of: COB_0000082
subclass of: Sensory Stimulation
subclass of: Stimulation Intervention
definition: A specific, designed execution of Sensory Stimulation with defined parameters, target modalities, intended effect, and delivery mechanism. An intervention can realize a session specification derived from a preset, protocol, or framework.

Sensory Stimulation Protocol
type: Class
subclass of: IAO_0000030
subclass of: OBI_0000272
subclass of: Stimulation Protocol
definition: A structured method specification for using one or more sensory stimulation techniques toward an intended use, including composition rules, timing, parameter ranges, constraints, and cautions. A protocol is narrower than a framework and can constrain many presets.

Sensory Stimulation Technique
type: Class
label: Tecnica di Stimolazione Sensoriale @it
label: Técnica de Estimulación Sensorial @es
label: Técnica de Estimulação Sensorial @pt
subclass of: IAO_0000030
subclass of: Stimulation Technique
definition: An information-content category for a reusable, parameterizable method of sensory stimulation, characterized by stimulus form, delivery mechanism, and any explicitly proposed response mechanism. A technique is less specific than a protocol and does not by itself provide enough detail to reproduce an intervention.

Sensory-Transduction-Bypassing Access Route
type: Class
subclass of: Neural Access Route
definition: A neural access route that reaches its target without canonical sensory receptor transduction, whether by physical neural interaction, biochemical or pharmacological engagement, or indirect non-sensory physiological mediation.
scope note: An asserted bypass route positively identifies such a route; it does not prove the technique is non-sensory, because a hybrid may also declare an intended sensory route. Absence of a sensory type is not OWL negation.

Session Instance
type: Class
subclass of: Activity
subclass of: Sensory Stimulation Intervention
definition: The record of an actual execution of a session specification, including timing, completion status, platform, and optional self-report. Append-only: never modified after creation.

Session Specification
type: Class
subclass of: IAO_0000030
subclass of: Plan
definition: A complete, reproducible description of a specific intended execution of a preset, including user-defined overrides of preset defaults. The unit of scientific reproducibility: given a specification and a conforming engine, the acoustic output is fully determined.

Source Governance Record
type: Class
subclass of: IAO_0000030
definition: An immutable record governing a research output used as evidence: source version and digest, custodian, access classification, consent/ethics basis or an explicit not-applicable determination, and permitted use scope, with generation time and a qualified responsible agent.

Stimulation
type: Class
label: Estimulación @es
label: Estimulação @pt
label: Stimolazione @it
subclass of: BFO_0000015
definition: A deliberately parameterized process in which structured physical energy, mechanical input, a chemical agent, or another controlled input is applied as a stimulus with a declared design intent to elicit, perturb, regulate, or probe an identified biological, sensory, or neural process. Mere exposure, administration, or energy transfer without that stimulation intent is insufficient. Classification does not assert excitation, conscious perception, response, benefit, or safety.
scope note: The neutral umbrella over sensory stimulation and interventional neuromodulation. It carries no commitment to an applied medium, delivery approach, biological access route, or anatomical target; those are recorded on separate facets (ADR 0034).

Stimulation Delivery Approach
type: Class
subclass of: IAO_0000030
definition: A coarse, non-exclusive operational category summarizing how an input is introduced or an interface is positioned — for example external, transcutaneous, transcranial, implanted, or systemic. Detailed device, body placement, administration, and dose remain in the exposure profile.
scope note: Values are deliberately non-exclusive: a method may be external, transcutaneous, and transcranial at once. No approach tag is inferred from any other facet.

Stimulation Intervention
type: Class
subclass of: COB_0000082
subclass of: Stimulation
definition: A specific, designed execution of a stimulation process with defined parameters, delivery, and intended effect. The neutral planned-process layer over sensory stimulation and neuromodulation interventions.
