GC Core Vocabularies

Scheme URI Concepts Description
Organization Type https://ontology.global.church/core#OrganizationTypeScheme 10 Classification of organizations by structural/governance form. Org types describe what an organization IS (Church, Agency, Network), not what it DOES — activity classification uses gc:EngagementAcceleratorScheme via gc:hasEngagementAccelerator.
Belief Type (may be superseded by HIS ROR) https://ontology.global.church/core#BeliefTypeScheme 10 Classification of organizations by Christian tradition, aligned with the World Christian Database (WCD) six-megabloc taxonomy. Layer 2 in the three-layer religion classification: HIS ROR (religion) → BeliefType (Christian tradition) → Denomination.
Denomination https://ontology.global.church/core#DenominationScheme 32 Classification of organizations by denomination. Two-level hierarchy with denomination families and specific bodies. Layer 3 in the three-layer religion classification: HIS ROR (religion) → BeliefType (Christian tradition) → Denomination. Informed by the World Christian Database (WCD) denomination taxonomy.
Engagement Accelerators https://ontology.global.church/core#EngagementAcceleratorScheme 61 Twelve strategic domains that catalyze phase transitions among people groups, as defined by the Phases of Engagement Toolkit (April 2026). Each accelerator represents a dimension of gospel-oriented activity whose priority varies by engagement phase.
Engagement Strength https://ontology.global.church/core#EngagementStrengthScheme 5 Five-level scale measuring the intensity and quality of gospel-oriented activity relative to the population at a given engagement phase. Strength is not a measurement of a team's quality or impact, but an indicator of gospel-oriented activity relative to the population. From the Phases of Engagement Toolkit (April 2026) by Frontiers, IMB, Joshua Project, Engage Network, Vision 5:9, and Accelerate.
Priority Levels https://ontology.global.church/core#PriorityLevelScheme 5 Five-level priority scale for accelerator phase profiles. Indicates how much investment an engagement accelerator warrants at a specific phase of engagement.
Claim Status https://ontology.global.church/core#ClaimStatusScheme 4 Status values for self-reported engagement claims. Tracks whether the claimed engagement is currently active, temporarily paused, completed, or withdrawn.
Assessment Methodology Scheme https://ontology.global.church/core#AssessmentMethodologyScheme 3 Identifies the framework or scale used for an assessment. Each concept represents a distinct assessment methodology owned by a specific organization.
Endorsement Status Scheme https://ontology.global.church/core#EndorsementStatusScheme 4 SKOS concept scheme for endorsement status values.
Endorsement Type Scheme https://ontology.global.church/core#EndorsementTypeScheme 4 SKOS concept scheme for endorsement types.
Practice Type Scheme https://ontology.global.church/core#PracticeTypeScheme 9 SKOS concept scheme containing the recognized practice types.
Resource Domain Scheme https://ontology.global.church/core#ResourceDomainScheme 23 Content domain classification for ministry resources. Hierarchical — top concepts are broad domains, narrower concepts are specializations.
Resource Format Scheme https://ontology.global.church/core#ResourceFormatScheme 8 SKOS concept scheme for resource delivery formats.
Resource Function Scheme https://ontology.global.church/core#ResourceFunctionScheme 8 How the resource is used — its pedagogical or ministry function.
Resource Status Scheme https://ontology.global.church/core#ResourceStatusScheme 5 SKOS concept scheme for resource lifecycle stages. Progression: NotStarted → Planned → InProgress → InReview → Available.
Theological Discipline Scheme https://ontology.global.church/core#TheologicalDisciplineScheme 22 The classical divisions of theological study. Used to classify theological education resources by academic discipline.

Joshua Project Vocabularies

Scheme URI Concepts Description
JP Progress Scale https://ontology.global.church/joshuaproject#JPProgressScaleScheme 5 Five-level classification (1-5) of the progress of church planting among a people group. Derived from percent evangelical and percent Christian adherent. Used by Joshua Project to assess reachedness.

Phases of Engagement Vocabularies

Scheme URI Concepts Description
Phases of Engagement https://ontology.global.church/poe#PhasesOfEngagementScheme 9 Eight-phase classification (0-7) of a people group's progress from zero engagement through indigenous church multiplication to sustained gospel presence. Each phase maps to a distinct engagement accelerator profile. Phase 0-R is a restart sub-indicator under Phase 0. Builds on the No Place Left '7 Phases of Progress' framework.

IMB Vocabularies

Scheme URI Concepts Description
Global Status of Evangelical Christianity https://ontology.global.church/imb#GSECScheme 7 Seven-level classification (0–6) of the global status of evangelical Christianity among a people group. Used by IMB to assess engagement and church planting progress.
Strategic Priority Index https://ontology.global.church/imb#SPIScheme 3 Three-category classification (0–2) used by IMB to prioritize people groups for strategic engagement. Combines engagement status and unreached status.
Church Planting Status https://ontology.global.church/imb#ChurchPlantingStatusScheme 3 Three-level classification of church planting activity among a people group: no churches planted, dispersed church planting, or concentrated church planting.
Evangelical Level https://ontology.global.church/imb#EvangelicalLevelScheme 11 Eleven-level ordinal classification of the estimated evangelical percentage of a people group into categorical bands. Lower notation values indicate fewer evangelicals.
IMB Target Audience Scheme https://ontology.global.church/imb#TargetAudienceScheme 8 IMB's classification of intended resource audiences.
IMB Affinity Region Scheme https://ontology.global.church/imb#AffinityRegionScheme 11 IMB's internal affinity-based regional classification. Not 1:1 with ISO regions.

HIS Registries

Scheme URI Concepts Description
HIS Registry of Geography https://data.global.church/his/rog 269 Geography classification used across the missions data ecosystem. Three-level hierarchy: Region (5) → Subregion (22) → Country (242). Country codes are HIS ROG codes (2-letter), cross-referenced to ISO 3166-1 alpha-3.
HIS Registry of Religions https://data.global.church/his/ror 46 Religion classification system used by IMB. Two-level hierarchy: ROR3 religion families (10) → ROR4 sub-traditions (36). 42 total codes.
