A reviewer-friendly overview for scientists and biologists

This ontology is a shared vocabulary and relationship map for DFO Pacific salmon data. Its job is to make terms like Conservation Unit, survey event, spawner abundance, reference point, and status zone mean the same thing across datasets, methods, assessments, and reporting products.

What this is

An operational ontology for Pacific salmon science, assessment, and data stewardship at DFO.
A way to connect field observations -> measurements/results -> assessments -> reference points and status concepts.
A place to standardize controlled vocabularies such as status zones, benchmark types, and method schemes.

What this is not

Not a complete ontology of salmon biology or ecology.
Not a replacement for scientific judgment or program-specific methods.
Not raw data; it is the schema and vocabulary that help raw data line up.

Suggested review path

Units: Conservation Unit, Population, Stock Management Unit, Stock.
Assessment flow: Survey event -> Spawner abundance / results -> Stock assessment -> WSP status zone and reference points.
Controlled vocabularies: go to the SKOS section for code-list style terms and approved value schemes.

How to use this page

Use Search terms at the top right, or press /.
Use the quick-jump chips for major sections.
Browse Classes for entities and processes, and Object properties for relationships.
Open WebVOWL for a high-level structure view, then use the detailed term pages when checking definitions and links.

Bigger picture: an authoritative set of definitions becomes much more useful when those terms travel into data dictionaries and databases via their persistent identifiers. That gives you a semantic contract between what your columns mean and how other people or downstream tools will reinterpret and reuse the data later, which makes integration across field programs, assessments, dashboards, and reporting products far less brittle.

DFO Salmon Ontology: Description back to ToC

This ontology is the reference vocabulary for DFO salmon data work.

For Salmon Data Package dictionaries and meta salmon workflows, treat the IRI as the authoritative definition of each term.

Keep your local column labels in whatever format helps your team (for example Spawner_Abundance, spawner abundance, or SpawnerAbundance).
Map each field to ontology IRIs in column_dictionary.csv (for example term_iri, and when needed property_iri, entity_iri, constraint_iri, method_iri).
Prioritize semantic match (definition + scope) over formatting match (capitalization, underscores, or minor wording differences).
If a needed term is missing, open a new-term issue in dfo-salmon-ontology.

Bottom line: local labels can vary, but the mapped IRI is the contract that keeps meaning consistent across data dictionaries, teams, and tooling.

Type-1, True Abundance, high resolution	Total, seasonal counts through fence or fishway; virtually no bypass. Simple, often single step analysis. Reliable resolution of between year differences >10% (in absolute units).
Type-2, True Abundance, medium resolution	Indirect estimate of total spawner abundance with qualified accuracy and known precision (i.e., a variance estimate—an explicit quantitative measure of uncertainty around the estimate). Derived from high-effort, standardized methods (e.g., mark-recapture, serial counts for area under the curve) with documented analytical conversions (including interpolation/calibration as needed). Reported in absolute units (estimate ± variance). Reliable resolution of between-year differences >25% (in absolute units).
Type-3, Relative Abundance, high resolution	Relative abundance index (i.e., not an absolute count) derived from moderate to high effort surveys (typically 3 or more site visits) using standardized methods applied consistently between and within years (e.g., equal-effort surveys executed by walk, swim, overflight). Accuracy and precision are not fully quantified (i.e., no explicit variance estimate), but are assumed stable enough for within-series comparisons. Reliable resolution of between-year differences >25% (in relative units).
Type-4, Relative Abundance, medium resolution	Low to moderate effort (1-4 trips), known survey method. Simple analysis by known methods. Reliable resolution of between year differences >200% (in relative units).
Type-5, Relative Abundance, low resolution	Low effort (e.g. 1 trip), use of vaguely defined, inconsistent or poorly executed methods. Unknown to ill defined; inconsistent or poorly executed. Uncertain numeric comparisons, but high reliability for presence or absence.
Type-6, Presence or Absence	Non-numeric, year-specific record of presence/not detected (i.e., present/absent without estimating a count), tied to an explicit time and location, with reliable species identification. Underlying field methods may be highly variable; analysis is not required.

Decisions about the conservation of CUs in the Amber zone will involve broader consideration of biological, social, and economic issues.
Amber/Green integrated status	Blended integrated status outcome between Amber and Green used when expert evidence supports an intermediate boundary outcome.
Data deficient integrated status	Integrated status outcome indicating insufficient information to assign a biological zone outcome.
Green zone	Social and economic considerations will tend to be the primary drivers for the management of Conservation Units in the Green zone, though ecosystem or other non-consumptive use values could also be considered.

Not-red integrated status	Binary integrated-status outcome indicating the Conservation Unit is not in Red status after binary collapse of integrated outcomes.

Undetermined integrated status	Integrated status outcome used when an assessment is unresolved or pending completion.

A fish stock experiencing serious harm may be depleted to the point where it has impaired productivity or reproductive capacity.

Serious harm may be irreversible, or only slowly reversible over the long-term, and can be due to fishing, other human-induced impacts, or natural causes. Under the Precautionary Approach policy and the Fish Stocks Provisions (FSPs), breaching the LRP is a trigger for a rebuilding plan.

in dimension^op back to ToC or Object Property ToC

IRI: http://www.w3.org/ns/dqv#inDimension

Represents the dimensions a quality metric, certificate and annotation allow a measurement of.

Dimensions are meant to systematically organize metrics, quality certificates and quality annotations. The Data Quality Vocabulary defines no specific cardinality constraints for dqv:inDimension, since distinct quality frameworks might have different perspectives over a metric. A metric may therefore be associated to more than one dimension. However, those who define new quality metrics should try to avoid this as much as possible and assign only one dimension to the metrics they define. More than one dimension can be indicated for each quality annotation or certificate.
