Engagement Accelerators

The Global.Church knowledge graph classifies mission engagement using EngagementAcceleratorScheme — a two-level SKOS ConceptScheme with 12 accelerators and 49 functions. Accelerators represent broad domains of engagement activity (e.g., Prayer, Scripture/Resource Access, Mobilization/Sending). Functions are the specific activities within each accelerator (e.g., Bible Translation, Pioneer Church Formation).

The scheme is loaded into the <https://data.global.church/vocabs/> named graph alongside other classification vocabularies.

Two-Level Hierarchy

Accelerators (L1) contain functions (L2) via standard SKOS relationships:

Code
 
gc:AccMobilization                             ← accelerator (L1)
  skos:narrower gc:FnCrossCulturalWorkerDeployment   ← function (L2)
  skos:narrower gc:FnShortTermMissionCoordination
  skos:narrower gc:FnMissionaryMemberCare
  ...

Functions point back to their parent accelerator via skos:broader. You can traverse the hierarchy in either direction.

Four accelerators — Vision Casting, Multi-node Engagement, Critical Contextualization, and Marketplace Involvement — describe strategic patterns rather than organizational functions. They have few or no narrower function concepts.

Three Classification Dimensions on Organization

Organizations in the knowledge graph are classified along three orthogonal dimensions:

Dimension	Property	Vocabulary	Question
Type	`gc:hasOrganizationType`	OrganizationTypeScheme (10 types)	What is it?
Engagement accelerator	`gc:hasEngagementAccelerator`	EngagementAcceleratorScheme (49 functions)	What does it do?
Belief	`gc:hasBeliefClassification`	BeliefTypeScheme (10 traditions)	What does it believe?

These dimensions are independent. A Mission Agency (AGN) might do Church Planting and Worker Mobilization. A Seminary (SEM) might do Leadership Development and Content Creation. A Parachurch Ministry (PAR) might do Meeting Needs/Compassion and Research. The org type tells you what kind of entity it is; engagement accelerators tell you what activities it performs.

Property Reference: `gc:hasEngagementAccelerator`

Detail	Value
Type	`owl:ObjectProperty`
Range	`skos:Concept` (from `gc:EngagementAcceleratorScheme`)
Multi-valued	Yes — an org or claim typically declares 3–4 functions
Applies to	`gc:Organization` and `gc:EngagementClaim`
Points to	Function-level (L2) concepts, e.g., `gc:FnBibleTranslation`, `gc:FnPioneerChurchFormation`

On Organizations, gc:hasEngagementAccelerator declares the functions the org performs as part of its mission. On EngagementClaims, it declares which functions the org is applying to a specific people group.

The 12 Accelerators

Aligned with the Phases of Engagement Toolkit (April 2026, Frontiers / IMB / Joshua Project / Engage Network / Vision 5:9 / Accelerate).

Code	Accelerator	Functions	Description
`PRA`	Prayer	4	Organized intercessory effort targeting specific unreached people groups, mobilizing sustained prayer and awareness in the global church.
`SRA`	Scripture/Resource Access	6	Translating, producing, and distributing Scripture and ministry resources in every language and format needed for people groups to access God's Word.
`VIS`	Vision Casting	2	Casting vision for unreached people groups and raising awareness to inspire action.
`MNE`	Multi-node Engagement	2	Coordinating engagement across multiple organizations and entry points for a single people group.
`MOB`	Mobilization/Sending	6	Recruiting, equipping, deploying, and sustaining cross-cultural workers in unreached fields.
`COL`	Collaborative Engagement	5	Facilitating collaboration, reducing duplication, and aligning strategy across multiple mission organizations.
`COM`	Meeting Needs/Compassion	6	Serving physical, social, and economic needs as an expression of the gospel in unreached communities.
`CTX`	Critical Contextualization	2	Adapting gospel communication and church forms to local cultural contexts without syncretism.
`RCI`	Research/Cultural Insights	4	Gathering, analyzing, and disseminating information about people groups, languages, and gaps to inform strategic mission decisions.
`TRN`	Training/Equipping	6	Forming and equipping pastors, church planters, and movement leaders through formal and non-formal theological education.
`MUL`	Multiplying Efforts	5	Catalyzing the formation, health, and multiplication of indigenous churches within unreached people groups.
`MKT`	Marketplace Involvement	1	Leveraging business and professional platforms for gospel access in restricted and creative-access contexts.

Notation Codes

Every concept carries a skos:notation value for use in API payloads and bridge mappings:

Accelerators use 3-letter codes: PRA, SRA, VIS, MNE, MOB, COL, COM, CTX, RCI, TRN, MUL, MKT
Functions use {accelerator}-{suffix} codes: PRA-INT (Intercessory Prayer Networks), SRA-BIB (Bible Translation), MUL-PIO (Pioneer Church Formation), etc.

Code
 
PREFIX gc:   <https://ontology.global.church/core#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>

SELECT ?concept ?label ?code WHERE {
  ?concept skos:inScheme gc:EngagementAcceleratorScheme ;
           skos:prefLabel ?label ;
           skos:notation ?code .
  FILTER NOT EXISTS { ?concept skos:broader ?parent }
}

This returns the 12 top-level accelerators. Remove the FILTER to get all 61 concepts (12 accelerators + 49 functions).

Querying Engagement Accelerators

Find all organizations doing multiplication functions

Traverse skos:broader from function to accelerator to find orgs performing any function under Multiplying Efforts:

Code
 
PREFIX gc:   <https://ontology.global.church/core#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>

SELECT ?org ?orgName ?functionLabel WHERE {
  ?fn skos:broader gc:AccMultiplication ;
      skos:prefLabel ?functionLabel .

  ?org a gc:Organization ;
       gc:name ?orgName ;
       gc:hasEngagementAccelerator ?fn .
}
ORDER BY ?orgName

To find orgs classified at the accelerator level instead:

Code
 
?org gc:hasEngagementAccelerator gc:AccMultiplication .

Find high-priority accelerators for a given phase

The gc:AcceleratorPhaseProfile class links accelerators to engagement phases with priority levels. Each profile instance asserts that a given accelerator has a specific priority (High, Medium, Low) at a given phase.

Code
 
PREFIX gc:   <https://ontology.global.church/core#>
PREFIX poe:  <https://ontology.global.church/poe#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>

SELECT ?acceleratorLabel ?priorityLabel WHERE {
  ?profile a gc:AcceleratorPhaseProfile ;
           gc:engagementPhase poe:PhaseP2 ;
           gc:acceleratorDomain ?accelerator ;
           gc:profilePriority ?priority .

  ?accelerator skos:prefLabel ?acceleratorLabel .
  ?priority skos:prefLabel ?priorityLabel .
}
ORDER BY ?priorityLabel

Resource Routing: The Strategic Question

The taxonomy unlocks a key coordination question: given a people group at phase X, what engagement accelerators are most needed, and which organizations perform those functions?

The conceptual query pattern joins three datasets:

AcceleratorPhaseProfile — which accelerators are high-priority at this phase?
EngagementAcceleratorScheme — which functions belong to those accelerators?
Organizations — which orgs declare those functions via gc:hasEngagementAccelerator?

Code
 
PREFIX gc:   <https://ontology.global.church/core#>
PREFIX poe:  <https://ontology.global.church/poe#>
PREFIX skos: <http://www.w3.org/2004/02/skos/core#>

SELECT ?org ?orgName ?functionLabel ?acceleratorLabel ?priorityLabel WHERE {
  # 1. High-priority accelerators at Phase 2
  ?profile a gc:AcceleratorPhaseProfile ;
           gc:engagementPhase poe:PhaseP2 ;
           gc:acceleratorDomain ?accelerator ;
           gc:profilePriority gc:PriorityHigh .

  ?accelerator skos:prefLabel ?acceleratorLabel .
  gc:PriorityHigh skos:prefLabel ?priorityLabel .

  # 2. Functions under those accelerators
  ?fn skos:broader ?accelerator ;
      skos:prefLabel ?functionLabel .

  # 3. Orgs performing those functions
  ?org a gc:Organization ;
       gc:name ?orgName ;
       gc:hasEngagementAccelerator ?fn .
}
ORDER BY ?acceleratorLabel ?orgName

This returns organizations matched to the highest-priority functions for a given phase — the foundation for routing the right resources to the right people groups at the right time.
