Research draft, second pass

A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description

Enable an agent to identify a subspecies concept, assess the evidence and authority supporting its recognition, and use its classification without concealing uncertainty or competing treatments.

A subspecies is a taxon ranked below species, generally recognized as a distinguishable population or group of populations within a species whose differentiation is judged insufficient for recognition as a separate species.

It can be Resolve a subspecies name to a taxon concept under a selected treatment.; Compare proposed diagnostic characters with evidence from sibling subspecies and other populations of the parent species.; Assess a specimen or observation against documented identification criteria and retain an uncertain assignment when necessary.; Compare competing circumscriptions and expose their disagreements.; Trace records through synonymisation, rank changes, splits, and mergers while preserving original identifications.; Flag uses that require separate conservation, legal, or management authority..

Distinguishing features

A cited taxonomic treatment explicitly assigns subspecies rank; geographic separation or visible difference alone does not establish it.

The concept is placed within a named parent species in the same treatment, distinguishing it from a separately recognised species.

A subspecies taxon comprises a circumscribed biological group, whereas subspecies rank is the classification category applied to that group.

Its recognition is distinguished from a breed, cultivar, variety, or informal population label by the treatment and applicable nomenclatural framework.

A scientific name is tracked separately from the taxon concept because different treatments may apply that name to different circumscriptions.

Characteristics

Modelled referent
taxonomic rank | taxon concept at subspecies rank Prevents statements about the rank from being confused with observations about a particular biological group.
Parent species placement
parent species concept and supporting treatment Establishes the classification within which subspecies recognition is meaningful.
Name and nomenclatural framework
scientific name record, applicable code, and nomenclatural anchor where applicable Supports name interpretation without treating nomenclatural standing as proof of taxonomic acceptance.
Recognition in a treatment
accepted at subspecies rank | synonymised | assigned another rank | unresolved | not assessed Makes recognition attributable to a particular authority and version.
Diagnostic character profile
reported morphological, genetic, behavioural, ecological, or combined character evidence Records how the proposed group can be distinguished and where identification remains uncertain.
Diagnostic character measurements
character-specific units, sample sizes, uncertainty, and comparator distributions Allows an agent to assess overlap and evidential strength without assuming a universal subspecies threshold.
Population and range circumscription
included, excluded, and uncertain populations; dated occurrence and range evidence Defines the biological extent of the concept and separates documented membership from geographic inference.
Relationship to competing concepts
equivalent | includes | included in | overlaps | disjoint | unresolved, with supporting treatment Supports comparison across revisions without assuming that matching names imply matching biological coverage.

Rank and taxon identity Distinguishes the subspecies category from particular taxa recognised within it.

An agent must establish which sense is intended and which parent species and treatment make a particular subspecies identifiable.

Referent and registry placement

Establishes the biological meaning of the entry and handles its unexplained organisational placement.

Subspecies referent

Record whether the target is the rank itself or a specific taxon concept; retain the supplied registry placement as an issue requiring review.

  1. Does this record describe subspecies rank generally or a particular biological group recognised at that rank? definition
  2. What registry evidence explains the SOC / SOC.ORG placement, and does it indicate an intended alternative sense? boundary

Species placement and treatment

Anchors a subspecies concept to its parent species and the treatment recognising it.

Treatment-qualified placement

Represent subspecies recognition as a classification assertion with a named parent species and attributable taxonomic treatment.

  1. Which parent species concept contains this subspecies in the selected treatment? boundary
  2. Which publication or versioned taxonomic resource explicitly recognises this group at subspecies rank? provenance
Names and nomenclatural anchors Records how a subspecies name is formed, anchored, and related to other names.

Reliable name resolution requires separating naming rules and name-bearing references from biological circumscription.

Name form and rules

Captures the complete name and the nomenclatural framework governing its interpretation.

Code-specific name record

Record name components, authorship, rank notation, and nomenclatural standing using the applicable framework's terminology.

  1. Which nomenclatural framework applies to this organism group and subspecies name? definition
  2. What original publication and subsequent nomenclatural acts support the recorded spelling, authorship, combination, and standing? provenance

Anchors and name relationships

Connects the name to its nomenclatural anchor and distinguishes different reasons that names are linked.

Name anchor and synonymy

Identify the applicable type or other nomenclatural anchor, and document whether linked names reflect nomenclatural relationships or taxonomic judgement.

  1. What type material, type locality, strain, or other anchor applies under the governing framework, and where is it documented? provenance
  2. For each linked name, what evidence distinguishes a nomenclatural relationship from a treatment's decision to combine biological groups? boundary
Differentiation and population boundaries Examines the characters, sampling, and population relationships used to delimit a subspecies.

A subspecies model must expose the evidence behind differentiation and the limits of assigning organisms to the proposed group.

Diagnostic evidence

Records proposed distinguishing characters and evaluates them against relevant comparison samples.

Comparative diagnosis

Document diagnostic claims, their comparison groups, variation, and sampling limits without imposing a universal differentiation threshold.

  1. Which characters distinguish this proposed subspecies from sibling subspecies and other sampled populations of the parent species? definition
  2. What measurements, sample sizes, geographic coverage, and within-group versus between-group overlap support each diagnostic claim? measurement
  3. Which studies establish whether the observed differences persist after accounting for age, sex, season, or environmental effects? provenance

Range, contact, and membership

Defines included populations and records uncertainty at geographic and biological boundaries.

Population circumscription

Separate documented population inclusion from inferred range boundaries and describe evidence from contact zones where available.

  1. Which populations are included, excluded, or unresolved, and what evidence supports those assignments? boundary
  2. Where populations meet, what evidence describes intergradation, gene flow, reproductive relationships, or gaps in sampling? measurement
  3. When is locality sufficient for a provisional identification, and when must an agent require diagnostic evidence or leave membership unresolved? action
Recognition, revision, and use Tracks competing classifications and supports responsible use of subspecies assignments.

Taxonomic disagreement and revision can alter the meaning of names and the applicability of records or downstream decisions.

Competing taxonomic treatments

Preserves differences in recognition, rank, and biological coverage across authorities.

Recognition and concept history

Record each treatment's position and map concept changes without silently replacing earlier interpretations.

  1. Which treatments accept the subspecies, synonymise it, assign another rank, or leave its status unresolved? provenance
  2. Does a revision preserve the same biological coverage, or does it split, merge, expand, or restrict the earlier concept? boundary

Record assignment and downstream use

Controls how identification records and decisions use a treatment-dependent subspecies concept.

Assignment and revision actions

Specify evidence needed for assignments and reassessments, preserving original determinations and linking separately governed consequences.

  1. What diagnostic evidence and selected treatment justify assigning a specimen, observation, or dataset record to this subspecies? action
  2. After a taxonomic revision, which records can be remapped from existing evidence and which require re-examination? action
  3. Which conservation or legal records explicitly refer to this name or circumscription, and what separate authority governs their interpretation? boundary
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.

Reported evidence

Findings from the breadth pass, kept separate from the structural claims.

Check these first

Recalled without web access and unsourced; every item is a lead to verify.

  • The ordinary biological sense is described; the supplied SOC.ORG domain appears inconsistent with that sense and should be checked.
  • Criteria for recognizing subspecies vary among organism groups and taxonomic authorities; nomenclatural codes govern names rather than settle biological boundaries.
  • This is recalled knowledge, without source verification; the listed kinds are nomenclatural distinctions, not an exhaustive biological classification.
  1. Which of these check these first hold for the sense of subspecies this model covers, and on what evidence? provenance

Recalled without web access and unsourced; every item is a lead to verify.

  • species - Species is the encompassing rank; a subspecies belongs within a species under the classification being used.
  • population - A population need not have formal taxonomic recognition; a subspecies is a recognized taxon at a specified rank.
  • variety - In botanical nomenclature, variety is a rank below subspecies.
  • breed - A breed is a domesticated group maintained through breeding practices, rather than necessarily a taxonomic subspecies.
  • ecotype - An ecotype is distinguished by adaptation to particular environmental conditions and need not be recognized at a formal taxonomic rank.

What the second pass must settle

  • Why is vr.tr.subspecies placed in SOC / SOC.ORG, and does the registry intend the biological taxonomic sense assumed in this draft?
  • Should this entry primarily model subspecies rank, particular taxa at that rank, or both through explicitly separated views?
  • Which organism groups and nomenclatural frameworks must the researched model cover, and what framework-specific exceptions require additional structure?
  • Which primary treatments establish defensible criteria for subspecies recognition in each covered group, including disagreement over those criteria?
  • Does an existing Vercy world model already cover this concept, requiring this registry entry to link to it rather than produce another publication?
