Global.Church Core Ontology

The activity of baptizing one or more new believers (from GAPPSRVC taxonomy).

The activity of forming or planting a new church gathering. Generates a gc:Church instance (prov:generated). Corresponds to entityType 'Church' in EEP.

A plan or protocol for church formation/planting — the intended pathway, not a single execution.

A discipleship session or program engaging believers in spiritual growth. Corresponds to entityType 'Discipleship' in EEP.

The activity of granting an endorsement — board approval, review process, renewal. Optional; use when modeling the decision/approval event. Links via prov:generated to the Endorsement entity.

The scope of applicability of the endorsement (e.g. ministry, program, campus, time period).

The activity of filing or submitting an engagement attestation — e.g. onboarding form submission, registration. Use prov:generated to link to the EngagementAttestation; prov:wasAssociatedWith for the agent who filed it. Renamed from gc:EngagementClaimSubmission in v0.31.0 for consistency with the attestation-backbone naming.

An evangelistic conversation where the gospel is shared with one or more people. Use gc:GospelConversationReport for recorded outcomes (response counts). Corresponds to entityType 'GospelConversation' in EEP.

Training or mentoring activity for developing ministry leaders (from GAPPSRVC taxonomy).

Distribution of gospel media materials such as films, audio, or literature (from GAPPSRVC taxonomy).

A planned step within a ministry plan. Use p-plan:isStepOfPlan to link to the plan, p-plan:isPrecededBy for ordering.

An input or output variable of a ministry plan step.

A report, profile, or assessment artifact describing a people group, its status, or its measured characteristics.

A ministry activity that corresponds to a planned step. Use p-plan:correspondsToStep to link to the p-plan:Step it realizes.

• p-plan:Activity
• Ministry Activity ^c

Deprecated: use gc:PracticeDefinition for the plan/pattern, gc:PracticeOccurrence for actual occurrences. Equivalent to gc:PracticeDefinition for backward compatibility.

A prayer activity covering a geographic area. Corresponds to entityType 'PrayerWalk' in EEP.

Activity of actually using or deploying a resource in ministry. Use prov:used to link to the resource; prov:wasAssociatedWith for the deploying organization.

A working group of persons collaborating on field activities within or across organizations.

A training event or program for equipping field workers (from GAPPSRVC taxonomy).

A rule or indicator used by a methodology to evaluate a dimension. Defines how a dimension is measured or classified.

A status value for an attestation from the attestation status vocabulary.

A report recording the outcomes of a baptism activity — number of people baptized. Links to the activity via prov:wasGeneratedBy.

The act of one ekklesia (or organization) formally sending and commissioning another ekklesia into a new sphere of ministry — planting a daughter church, dispatching an apostolic band, authorizing a new expression. Subclass of prov:Activity. Mirrors gc:EndorsementIssuance (v0.15.0) as the canonical Activity + Entity pattern in GC-Core. Links via prov:generated → the commissioned gc:Ekklesia, prov:wasAssociatedWith → the sending gc:Organization (typically a gc:Ekklesia). For lightweight commissioning without provenance-rich modeling, use gc:sentFrom directly on the Ekklesia instance.

A status value for a gc:Commitment from the commitment status vocabulary (gc:CommitmentStatusScheme). 7 values: Declared, Funded, InProgress, Fulfilled, PartiallyFulfilled, Abandoned, Expired.

A dated lifecycle assertion about a specific ekklesia made by a recognized agent. Subclass of gc:Attestation. Each lifecycle transition (Forming → Established → Multiplying → Stalled → Reconstituting → Dissolved) is a separate EkklesiaAttestation event. The attestation chain provides the audit trail; gc:hasEkklesiaLifecycle on the Ekklesia instance is materialized from the latest non-superseded attestation. Inherited from gc:Attestation: gc:attestationSubject (→ the Ekklesia), gc:attestedBy (issuing agent), prov:generatedAtTime (timestamp), gc:attestationStatus, gc:fulfillsCommitment (optional), gc:basedOn (optional evidence URI), gc:attestationSignature, gc:attestationContentHash.

A document or artifact supporting the endorsement (statement of faith, doctrinal agreement, audit report, partnership history).

A status value for an endorsement from the endorsement status vocabulary.

The actual ministry activity or engagement process. Use when the attestation refers to a concrete prov:Activity (e.g. a specific church planting initiative) rather than a general situation.

A plan, protocol, or recurring pattern for ministry work. Subclass of prov:Plan and p-plan:Plan. Use for church formation pathways, training curricula, discipleship methods, prayer-walk protocols, etc.

• p-plan:Plan
• Plan ^c

A status value for a gc:Need from the need status vocabulary (gc:NeedStatusScheme).

A single occurrence of a practice — e.g., the prayer meeting that happened on a specific date. Links to its definition via gc:realizesPracticeDefinition.

A type of practice from the practice vocabulary. Modeled as a SKOS Concept so the vocabulary is extensible without schema changes.

Delivery format or medium of a resource, orthogonal to content type.

Lifecycle status of a mission resource.

A dimension or aspect of what is being evaluated (e.g. reachedness, gospel access, scripture availability, movement progress). A methodology specifies which dimensions it uses.

• assesses dimension ^op
• uses dimension ^op

A rule or standard the endorsement satisfies (e.g. doctrinal alignment, ministry verification, financial audit).

• satisfies criterion ^op
• uses criterion ^op

A type of endorsement from the endorsement type vocabulary.

An individual human agent. Minimal slice shipped in v0.32.0 to satisfy the attestationSubject range for gc:TrainingAttestation. Disciples in the Multiply ecosystem are modeled as gc:Person instances with opaque personalIdentifier (typically a Privy DID). PII never appears in the graph — personal names, contact info, and other identifying fields stay in per-app scoped storage. Phase 9b will extend with gc:personRole + PersonRoleScheme.

• Agent ^c
• foaf:Person

• member of ekklesia ^op
• personal identifier ^dp

Contextual suitability relation — a resource being suitable, intended, recommended, or deployed for a people group. Use instead of or in addition to direct gc:resourceForPeopleGroup when modeling contextual targeting.

• about resource ^op
• applies to people group ^op

A curated set of resources forming a coherent series, curriculum, or toolkit (e.g., a teaching series, a numbered paper collection, a multi-lesson curriculum).

Links an engagement accelerator to a phase of engagement with a priority level, forming the accelerator-phase matrix. Each profile instance asserts that a given accelerator domain has a specific priority (High, Medium, Low, Minimal, Inverted) at a given engagement phase.

• accelerator domain ^op
• engagement phase ^op
• profile priority ^op

A recorded report or observation about a ministry activity. Use prov:wasGeneratedBy to link to the activity that produced it.

• Baptism Report ^c
• Gospel Conversation Report ^c

A community manifestation of a people group emphasizing social cohesion, shared practice, identity, and interaction patterns.

• engages people group community ^op
• has community manifestation ^op

A dated claim by an agent that a subject (typically a gc:Person) has been trained in, is practicing, or is teaching a discipleship tool. Subclass of gc:Attestation. Disciple-first: the typical author is the subject themselves (self-attest); shepherds corroborate via a second attestation with gc:corroborates pointing at the disciple's. No identity reconciliation — the corroboration pattern makes two independent dated claims about the same subject trustworthy when both agents sign it. Introduced in v0.32.0 (Phase 10a).

• training date ^dp
• training level ^op
• training tool ^op

A semantic description/specification of an assessment method. Defines what is measured and how. Link to SKOS concepts in gc:AssessmentMethodologyScheme for vocabulary governance. Use gc:methodologyConcept to link a methodology to its published concept.

• methodology concept ^op
• uses criterion ^op
• uses dimension ^op

A situation-layer manifestation of a church community used for community-level state facts (e.g., active status, believers).

• number of baptized believers ^dp
• number of believers ^dp
• community state of church ^op

A situation-layer manifestation of a church gathering used for gathering-level state facts (e.g., attendance, language used when gathering).

• language used when gathering ^dp
• number of people attending ^dp
• gathering state of church ^op

A situation-layer state slice of an organization, used for time-varying attributes that should not be modeled as intrinsic organization identity facts.

• is active ^dp
• organization state of ^op

A geospatial place record sourced from the Overture Maps Foundation (overturemaps.org) open-source map dataset. In the Global.Church schema, Overture records represent church or place-of-worship locations identified via the Overture Maps 'places' theme. Each record is an entity with spatial coordinates and metadata linking it to people groups and locations. Aligned with OGC GeoSPARQL as a geo:Feature.

• geo:Feature
• Entity ^c

• Overture category ^dp
• Overture ID ^dp
• Overture location ^op
• targets people group ^op

Ongoing production effort — translation project, resource creation, draft development. Completion percentage and estimated completion date belong here, not on the resource itself. Use prov:generated to link to the future or in-progress resource.

• project completion percentage ^dp
• project estimated completion date ^dp
• targets resource ^op

The contextual relation among organization, people group(s), place, and engagement type. A DUL Situation that the attestation asserts exists or existed. Use when modeling richer semantics (multiple orgs, roles, partial engagement).

• classifies engagement type ^op
• has scope country ^op
• involves organization ^op
• involves people group ^op

An atomic finding, measurement, or assertion in an assessment result. Use for per-dimension values with provenance (e.g. evidence, confidence, source). Enables uniform modeling of jp:evangelicalPercentage, imb:gsecLevel, poe:phase, etc.

• assesses dimension ^op
• confidence score ^dp
• datum about people group ^op
• datum literal value ^dp
• datum value ^dp

An evaluation of a people group by an organization using a specific methodology. Assessments answer questions like 'how reached is this group?', 'what resources are available?', or 'what phase of progress has been achieved?' Each assessment is performed at a specific point in time, by a specific organization, using a declared methodology. The methodology identifies what was measured and how. An assessment produces one or more result snapshots containing the actual data points.

• assessed by ^op
• assesses ekklesia ^op
• assesses people group ^op
• assessment date ^dp
• assessment methodology ^op
• uses methodology ^op
• assessment target ^op

A report recording the outcomes of a gospel conversation — response counts, language, etc. Links to the conversation via prov:wasGeneratedBy.

• already following response ^dp
• interested response ^dp
• language of conversation ^dp
• negative response ^dp
• positive response ^dp
• total heard ^dp
• unknown response ^dp

A declared gap that one or more organizations could potentially meet. Concrete (a specific ministry resource required for a people group) or thematic (a capacity gap across a region). A Need is an information artifact (not an Attestation) — it describes an absence or gap rather than a positive claim. Multiple organizations may respond to the same Need via gc:Commitment. Attestations close the loop via gc:fulfillsCommitment. Phase 8 joint design memo (2026-04-16), Q3 lock.

• iao:0000030
• Entity ^c

• concerns country ^op
• concerns people group ^op
• need declared at ^dp
• need declared by ^op
• need description ^dp
• need status ^op

A dated declarative claim by or on behalf of an organization asserting engagement work with one or more people groups. Subclass of gc:Attestation. Collected through the onboarding flow when ministry leaders declare what types of engagement work their organization is doing (e.g., church planting, Bible translation, prayer). Use gc:aboutEngagementSituation to link to the situation being claimed; or use direct properties (claimingOrganization, claimedPeopleGroup, etc.) for the simple case. Renamed from gc:EngagementClaim in v0.30.0; legacy alias removed in v0.31.0.

• about engagement activity ^op
• about engagement situation ^op
• claim date ^dp
• claim description ^dp
• claimed country ^op
• claimed people group ^op
• claiming organization ^op

A local gathering of believers — may or may not formally identify as a 'church'. Includes house churches, cell groups that function as churches, and traditional congregations. Subclass of Organization with church-specific structure (community state, gathering state, practices, demographics). Other organization types (Mission Agency, Denomination, Network, etc.) remain classified via gc:hasOrganizationType SKOS concepts — Church is promoted to a subclass because it has distinct properties and validation requirements.

• campus name ^dp
• has appointed leaders ^dp
• has community state ^op
• has gathering state ^op
• identifies as church ^dp
• is multi-campus ^dp
• services info ^dp

• community state of church ^op
• gathering state of church ^op

An organization's stated intent to engage in specific ministry work, optionally in response to a declared gc:Need. A Commitment is an information artifact and prov:Entity. It is separate from an Attestation: a Commitment expresses future/ongoing intent; an Attestation records a dated declarative claim about actual engagement. Attestations close the loop via gc:fulfillsCommitment (declared on gc:Attestation). The linkage between a Commitment and the Need that prompted it uses prov:wasInfluencedBy (PROV reserved path — do not redefine). Phase 8 joint design memo (2026-04-16), Decision 4.

• concerns people group ^op
• target completion date ^dp

A standing practice, pattern, or protocol that a church community performs (e.g., weekly communion, believer's baptism). Represents the intended/recurring pattern, not a single occurrence. Use gc:PracticeOccurrence for actual instances.

• p-plan:Plan
• Plan ^c

• is performed internally ^dp
• practice date adopted ^dp
• practice definition type ^op
• practice frequency ^dp
• practice is active ^dp

• has practice (deprecated) ^op
• has practice definition ^op
• realizes practice definition ^op

A contextual body of believers exercising the functions of an assembled church within their sphere — local, extra-local, regional, missional. Broader than gc:Church (which is one Form — specifically a local gathering). Ekklesia encompasses local congregations, house churches, apostolic bands in mission, regional/city-church expressions, and missional orders. Principle 12 is preserved: the four Ekklesia-specific axes (Form, Ecclesial Mode, Gathering Mode, Lifecycle) are scoped to gc:Ekklesia instances only — the parent gc:Organization class retains its two-axis rule (OrgType + EngagementAccelerator). Auto-inference: any instance with gc:hasOrganizationType gc:OrgTypeChurch is inferred as gc:Ekklesia via a SPARQL CONSTRUCT rule (Track 5). Pre-declaration communities may use gc:Team until ecclesial declaration or gc:Ekklesia + Lifecycle=Forming for traditions with a functional threshold.

An organizational endorsement — a certification, partnership, affiliation, or accreditation from a recognized body. An Attestation and information artifact. Applies to any gc:Organization (churches, agencies, networks, etc.). Provides multi-source trust signals on organization records. Re-anchored under gc:Attestation in v0.30.0 (previously subclassed the now-removed gc:TrustAssertion).

A dated declarative claim by an agent about a subject entity. Information artifact and prov:Entity. Superclass of gc:EngagementAttestation (self-reported engagement work), gc:Endorsement (partner/accreditation signal), and gc:EkklesiaAttestation (ekklesia lifecycle assertion). Any agent may issue an attestation; trust-weighting and stage-specific corroboration rules are enforced at the SHACL layer or at application-level trust scoring, not in the T-box.

• A social collective defined by the Lausanne boundary condition: the largest group within which the Gospel can spread as a church planting movement without encountering barriers of understanding or acceptance. Boundaries are functional (communication topology), not intrinsic — drawn where linguistic, cultural, social, or identity barriers impede natural gospel propagation. The grouping follows a maximality principle: do not subdivide unless a barrier exists, do not combine across one. Operationalized through HIS ROP3 codes encoding current consensus about where barriers lie. Linked via gc:hasPeopleClassification.

A ministry organization, church, alliance, network, denomination, or sending agency. Central organizational entity in the Global.Church schema. Organization subtypes are classified via gc:hasOrganizationType → OrganizationTypeScheme SKOS concepts (multi-valued: an org can have multiple types). gc:Church is promoted to an OWL subclass because it has distinct structure (community/gathering state, practices, demographics); other org types remain as SKOS concepts. Modeled as an Agentive Social Object (DOLCE ASO) with collective intentionality — orgs can commit to serving people groups, endorse peers, deploy workers, and bear responsibility for ministry activities.

A snapshot of findings from an assessment. An information artifact containing recorded findings — org-specific data points may live as properties on the result, or as gc:AssessmentDatum instances for finer-grained provenance. The result is immutable — when the organization reassesses, a new Assessment/Result pair is created. Old results persist in the graph for temporal tracking.

Links the attestation to the engagement activity it asserts. Use when the attestation refers to a concrete prov:Activity.

Links the attestation to the engagement situation it asserts. Use when modeling the richer DUL pattern; the situation holds involvesOrganization, involvesPeopleGroup, hasScopeCountry, classifiesEngagementType.

Links a ResourceApplicability situation to the resource.

The engagement accelerator this profile applies to. Points to a top-level concept from gc:EngagementAcceleratorScheme (e.g., gc:AccPrayer, gc:AccScriptureAccess).

Links a ResourceApplicability to the people group the resource is suitable for.

The organization that performed this assessment. May also be expressed via prov:qualifiedAssociation on the activity.

Links an AssessmentDatum to the dimension it evaluates.

Links an Assessment to the gc:Ekklesia being evaluated. Tier-2 specialization of gc:assessmentTarget — used by church-health methodologies (Church Circle, IMB 12 Healthy Church Characteristics, Exponential Five Levels, NCD).

Links an Assessment to the PeopleGroup being evaluated. Tier-3 specialization of gc:assessmentTarget.

The methodology or framework used for this assessment. Points to a SKOS concept in gc:AssessmentMethodologyScheme. For semantic methodology description, use gc:usesMethodology.

Links a denomination concept (from gc:DenominationScheme) to its parent belief type concept (from gc:BeliefTypeScheme). Enables cross-layer queries: given a denomination, find the Christian tradition it belongs to.

Links a ministry activity to the geographic location where it occurred.

Current status of the attestation. Points to a SKOS concept from gc:AttestationStatusScheme (Active, Paused, Completed, Withdrawn). Endorsements MAY use gc:endorsementStatus with its own vocabulary instead.

The entity this attestation is about — typically a gc:Organization, gc:Ekklesia, gc:PeopleGroup, or gc:EngagementSituation. Every attestation must have exactly one subject; subclasses may specialize the range via SHACL.

Optional free-form URI reference to evidence, documentation, or another entity the attestation relies on (e.g., a survey report, field note, prior attestation). v1 range is intentionally loose — tighten when seed data shows what's actually referenced. Distinct from prov:wasDerivedFrom, which is reserved for derivation from a specific prov:Entity within this graph.

The country where this engagement takes place. Points to a ROG SKOS concept (e.g., rog:PK for Pakistan). Optional — if absent, the attestation applies to the people group globally.

A people group that the organization claims to be engaged with. Multi-valued — an org may claim engagement across multiple people groups in a single attestation.

The organization that made this engagement attestation. Subproperty of gc:attestedBy (shared attestation backbone).

Links an EngagementSituation to the engagement type that classifies it. Points to EngagementTypeScheme concepts. Use when modeling via the situation.

The engagement accelerator(s) or function(s) this commitment covers. Points to SKOS concepts from gc:EngagementAcceleratorScheme (top-level accelerators or narrower function concepts). Multi-valued — a commitment can span multiple accelerators or functions.

Current status of the commitment. Points to a SKOS concept from gc:CommitmentStatusScheme (Declared, Funded, InProgress, Fulfilled, PartiallyFulfilled, Abandoned, Expired).

The organization making this commitment. Required — every Commitment must have a committing organization. A single commitment belongs to exactly one organization; multiple organizations making the same commitment do so as separate Commitment instances.

Links a Need to a country in which the gap exists. Points to a ROG SKOS concept (e.g., rog:AF for Afghanistan). Multi-valued (zero or more).

Links a Commitment to the Need it is responding to. Optional — a commitment may be made proactively without a prior Need declaration. A Need may attract multiple Commitments.

Links a Need to a people group the gap concerns. Multi-valued (zero or more). A Need with no people group link represents a thematic/regional gap not scoped to a specific people group.

• Commitment ^c
• Need ^c

Links a ministry activity to the religious background of the engaged people. Points to a ROR SKOS concept.

The language of the primary content (spoken, written). Use for clarity when resourceLanguage is ambiguous (e.g. apps with multiple language aspects).

Links an attestation to a prior attestation it affirms. Enables distributed trust without identity reconciliation — two independent dated claims about the same subject, each with its own attestedBy, that happen to agree. First shipped in v0.32.0 to support the disciple-self-attest → shepherd-corroborate pattern in Multiply. Cross-subclass: a TrainingAttestation may corroborate any gc:Attestation and vice versa. Minimum-corroboration rules for specific lifecycle stages (e.g., EkklesiaAttestation Multiplying requires at least one non-self corroboration) remain deferred to a later SHACL pass.

Links an AssessmentDatum to the PeopleGroup it describes.

Links a resource to its development/translation project. Completion percentage and estimated date belong on the project.

The organization that received this endorsement.

Links to a document or artifact supporting this endorsement (statement of faith, audit, partnership history).

Current status of the endorsement.

Classifies the endorsement by type from the EndorsementType vocabulary.

The organization that granted this endorsement.

The phase of engagement this profile applies to. Points to an poe:PhasesOfEngagementScheme concept (e.g., poe:Phase1 through poe:Phase7).

The engagement strength level at the assessed phase. Points to a concept from gc:EngagementStrengthScheme (Unknown, Initial, Growing, Active, Flourishing). Measures the intensity and quality of gospel-oriented activity relative to the population.

Links a ministry activity to a people group it engaged.

Links a ministry activity to a people group community manifestation it engages.

Records an Exponential Five Levels growth-trajectory rating for a church. Range: skos:Concept in exp:FiveLevelsScheme (Subtracting / Plateauing / Adding / Reproducing / Multiplying). Distinct from gc:hasEkklesiaLifecycle: the Lifecycle scheme is a descriptive six-stage life-arc including Stalled/Reconstituting/Dissolved; Exponential is a normative growth ladder with Multiplying as apex. Used on gc:AssessmentResult.

Links an attestation to a gc:Commitment it claims to fulfill (fully or partially). The fact of fulfillment is itself a dated agent claim, hence placed on the attestation rather than on the committed entity. Memo Decision 3 (2026-04-16). A single attestation may fulfill multiple commitments; a commitment may be referenced by multiple fulfillment attestations over its lifetime.

Links an ekklesia to an organization typed gc:OrgTypeMovement that catalyzed or generated it. Movement-generated ekklesias flag bodies born from a specific movement impulse (e.g., a house church produced by a No Place Left DMM movement). This enables the query 'how many ekklesia has movement M produced?' (inverse walk: ?e gc:generatedByMovement ?movement). The inverse direction — a movement linking to ekklesia it generated — is expressed by walking this property in reverse in SPARQL. Movements are not themselves ekklesia; this property connects ekklesia instances to their generative movement.

Classifies an organization by Christian tradition. Values are SKOS concepts from gc:BeliefTypeScheme — WCD-aligned megablocs: Protestant, Independent, Anglican, Catholic, Orthodox, Marginal, Unaffiliated, Other. Multi-valued.

Links a PeopleGroup social identity to a community manifestation of that group.

Links a church to its community state slice.

Materialized link from a gc:Ekklesia to its latest non-superseded gc:AssessmentResult per assessment methodology. Populated by scripts/inference/ekklesia-current-health.rq — analogous to Rule B for gc:hasEkklesiaLifecycle. The full assessment history remains authoritative; this property is a query-acceleration cache produced by re-running the CONSTRUCT after each load. May be multi-valued when an Ekklesia has been assessed under multiple methodologies (e.g., both Church Circle and IMB 12 Characteristics).

Links an AssessmentResult to an atomic finding.

Classifies an organization by denomination. Values are SKOS concepts from gc:DenominationScheme — hierarchical taxonomy of 18 denomination families (Baptist, Methodist, Presbyterian, Lutheran, Reformed, Pentecostal, Holiness, Adventist, Mennonite, etc.) with narrower concepts for specific bodies. Multi-valued.

Classifies an ekklesia by its operational mode — Modality (settled, gathered, parish/congregational) or Sodality (sent, selective, translocal). Multi-valued: an ekklesia may operate in both modes simultaneously, e.g. a settled local church with a live apostolic engine inside it. Points to SKOS concepts from gc:EcclesialModeScheme. Based on Ralph Winter's Two Structures framework. Optional.

Classifies an ekklesia by structural form. Points to a SKOS concept from gc:EkklesiaFormScheme (LocalChurch, HouseChurch, RegionalChurch, ApostolicBand, MissionalOrder). Single-valued for v1 — each ekklesia has one primary form. Required per SHACL (Track 4).

The current lifecycle stage of this ekklesia. Points to a SKOS concept from gc:EkklesiaLifecycleScheme (Forming, Established, Multiplying, Stalled, Reconstituting, Dissolved). OPTIONAL per SHACL (v0.34.3) — asserted only when a gc:EkklesiaAttestation chain exists for this Ekklesia. MATERIALIZED from the latest non-superseded attestation via a SPARQL CONSTRUCT rule (ontology/scripts/inference/ekklesia-lifecycle-latest.rq). The authoritative source is always the attestation chain; this property exists for query convenience. Absent under open-world semantics means no attester has produced a stage — which is the common case for the ~37K bridge-materialized OrgTypeChurch organizations auto-typed as gc:Ekklesia. The Phases of Engagement Toolkit scopes its phases to people groups (or geographic areas), not individual ekklesia, so a per-body lifecycle value is only meaningful when a real attestation exists. Closest precedent: gc:resultSupersedes chain in gc-assessment.ttl — latest non-superseded gc:AssessmentResult wins.

Links an organization to an endorsement it has received. Convenience navigation property (inverse direction of gc:endorsedOrganization).

The engagement accelerator(s) or function(s) this entity is engaged in. Points to SKOS concepts from gc:EngagementAcceleratorScheme — either top-level accelerators (gc:AccPrayer, gc:AccScriptureAccess, etc.) or narrower function concepts (gc:FnBibleTranslation, gc:FnPioneerChurchFormation, etc.). Multi-valued — an org or attestation can declare multiple accelerators/functions. Applies to both gc:Organization and gc:EngagementAttestation. Also usable on gc:Need (no domain restriction).

Links an organization to an engagement attestation it has made. Convenience navigation property (inverse direction of gc:claimingOrganization). Renamed from gc:hasEngagementClaim in v0.30.0; legacy alias removed in v0.31.0.

Describes how an ekklesia physically convenes. Multi-valued: a post-COVID church that gathers both in person and online carries both gc:GatheringInPerson and gc:GatheringOnline. Points to SKOS concepts from gc:GatheringModeScheme (InPerson, Online, Distributed). 'Distributed' models asynchronous/multi-node bodies (persecution contexts, diaspora fellowships) distinct from synchronous online gathering. Optional.

Links a church to a gathering state slice (e.g., a particular gathering context).

Links an entity to its geography classification in the HIS Registry of Geography (ROG) SKOS concept scheme. Three-level hierarchy: Region → Subregion → Country. The linked SKOS concept carries the ROG code via skos:notation and the place name via skos:prefLabel.

Links an entity to its language classification in the HIS Registry of Languages (ROL) SKOS concept scheme. The linked SKOS concept carries the ISO 639-3 code via skos:notation and the language name via skos:prefLabel.

Links an organization to a situation-layer state slice describing time-varying facts.

Classifies an organization by type. Values are SKOS concepts from gc:OrganizationTypeScheme (Church, Mission Agency, Denomination, Network, Coalition, Seminary, Parachurch Ministry). Multi-valued: an org can have multiple types.

Classifies an organization by its operational capabilities — what it is equipped to do. Values are SKOS concepts from gc:OrganizationalCapabilityScheme (18 top-level capabilities + ~77 narrower function concepts spanning parish, denominational, mission, and infrastructure work). Multi-valued: an org can carry many capabilities. Coexists with gc:hasEngagementAccelerator on gc:Organization — the capability scheme answers 'what can this org do?' across all kinds of Christian organizations; the accelerator scheme answers 'what does this org do for a specific people group?' per the Phases of Engagement Toolkit. Overlap is intentional and orthogonal — see Principle 12 (three classification axes: Form / Engagement Accelerator / Organizational Capability). Introduced v0.33.0.

Links a PeopleGroup to its classification in the HIS Registry of Peoples (ROP) SKOS concept scheme. The linked SKOS concept carries the raw code via skos:notation and the hierarchy via skos:broader.

Links a PeopleGroup social identity to a population manifestation of that group.

Deprecated: use gc:hasPracticeDefinition. Same range for backward compatibility.

Links an organization to a practice definition (pattern/protocol) it performs. Replaces gc:hasPractice for the plan layer.

Links an entity to its religion classification in the HIS Registry of Religions (ROR) SKOS concept scheme. The linked SKOS concept carries the ROR code via skos:notation and the religion name via skos:prefLabel.

Links an EngagementSituation to the country that scopes it. Points to ROG SKOS concept. Use when modeling via the situation.

Links a ministry activity to the language used during the activity. Points to a ROL SKOS concept.

People group the resource was designed or intended for.

Links an EngagementSituation to the organization involved. Use when modeling via the situation.

Links an EngagementSituation to a people group involved. Use when modeling via the situation.

The lifecycle stage this attestation asserts holds for the subject ekklesia. Required on every gc:EkklesiaAttestation. Points to a SKOS concept from gc:EkklesiaLifecycleScheme. SHACL (Track 4) enforces: when lifecycleAsserted ∈ {gc:LifecycleEstablished, gc:LifecycleMultiplying, gc:LifecycleReconstituting}, gc:hasEkklesiaForm is also required on the attestation.

Links a person to an ekklesia they claim membership in. Disciple-asserted and disciple-revocable per Multiply HARD INVARIANT #3. No inverse property minted in v0.32.0 — the reverse-walk query is cheap. Named with the explicit -Ekklesia suffix to avoid collision with the existing gc:isMemberOf (v0.21.0, org → org coalition/network membership).

Links an AssessmentMethodology to its vocabulary concept in gc:AssessmentMethodologyScheme.

The agent (organization, person, or network) that declared this need. Distinct from gc:attestedBy — a Need is not an Attestation. The declaring agent may be the organization experiencing the gap, or a coordinating body surfacing gaps on behalf of the field.

Current status of the need. Points to a SKOS concept from gc:NeedStatusScheme (Open, Partially Met, Met, Withdrawn).

Links an Overture place record to its geographic Location (a geo:Feature). The Location carries geometry via geo:hasGeometry or gc:latitude/gc:longitude.

Links an individual resource to the collection or series it belongs to.

Classifies a practice definition by its type from the PracticeType vocabulary.

The priority level for this accelerator at this phase. Points to a concept from gc:PriorityLevelScheme (High, Medium, Low, Minimal, Inverted).

Links a PracticeOccurrence to the PracticeDefinition it instantiates.

People group an organization recommends this resource for.

Links a resource to an engagement accelerator concept it contributes to (e.g., Scripture, Film, Church Planting). Values are SKOS concepts.

Links an ActivityReport to the ministry activity it describes. Inverse of prov:wasGeneratedBy when the activity generated the report.

Organization that created or authored the resource.

Organization that distributes or hosts the resource.

The content domain of the resource (e.g., Scripture, Evangelism, Discipleship, Leadership). Multi-valued. Constrained via SHACL to gc:ResourceDomainScheme concepts.

The delivery format or medium of the resource, orthogonal to its content type. Multi-valued when the same content is available in multiple formats.

How the resource is used — its pedagogical or ministry function (e.g., Curriculum, Manual, Tool, Broadcast). Constrained via SHACL to gc:ResourceFunctionScheme concepts.

Organization that created or provides the resource. Prefer resourceCreator, resourcePublisher, or resourceDistributor when the role is known. Kept for backward compatibility.

Organization that publishes or makes the resource available.

Current lifecycle status of the resource.

Organization that translated the resource into this language/version.

Links an AssessmentResult to the gc:Ekklesia it describes. Tier-2 specialization of gc:resultTarget.

Links an AssessmentResult to the PeopleGroup it describes. Tier-3 specialization of gc:resultTarget.

Links a newer AssessmentResult to the prior result it supersedes. For longitudinal tracking.

Links to a criterion this endorsement satisfies.

Flat shortcut: this ekklesia was sent or commissioned from the given organization. Range is gc:Organization because gc:Ekklesia is a subclass of gc:Organization — the common case is Ekklesia → Ekklesia (e.g., an apostolic band sent from a local church). For rich provenance with commissioning date and covenant terms, use gc:Commissioning + prov:wasAssociatedWith instead. This property is asserted directly when provenance is thin, or materialized from the commissioning activity when it is rich.

Links an organization to a people group it primarily serves or ministers to. Multi-valued: an organization can serve multiple people groups. Distinct from gc:targetsPeopleGroup (geographic association on Overture records) — this property represents intentional ministry focus declared by the organization.

Links an organization to a people group population manifestation it serves.

Links an Overture place record (or other entity) to a people group associated with its geographic area.

Links a development project to the resource it is producing. Inverse of gc:developmentProject.

The level at which the subject is operating in this tool. Points to a skos:Concept in gc:TrainingLevelScheme (Unlearned, Learning, Practicing, Teaching). Collapses Multiply's separate command-style (obeying/teaching) and skill-style (practicing/teaching) axes into a single attainment scale.

The discipleship tool this attestation is about. Points to a skos:Concept in gc:DiscipleshipToolScheme (the anchor) or to a narrower concept in a subscribed pack (future registry pattern, Phase 11 Shared Registries). Range intentionally loose in the T-box; SHACL tightens via scheme membership.

Union range — may target a PeopleGroup (tier 3, the original case), an Ekklesia (tier 2 church health), an Organization, or a Person (tier 1 disciple health). Tier-specific subproperties (gc:assessesPeopleGroup, gc:assessesEkklesia, etc.) preserve range information; this superproperty enables uniform discovery across all assessment tiers.

• assesses ekklesia ^op
• assesses people group ^op

Links a resource to a people group it targets or serves. For contextual suitability (intended/recommended/used), use gc:ResourceApplicability.

• intended for people group ^op
• recommended for people group ^op

• result for people group ^op

The date and time when the ministry activity ended.

Street address of the location.

Number of people who were already following Christ.

The date and time when the assessment was performed. Convenience subproperty of prov:startedAtTime.

Optional content-addressable hash of the attestation's canonical payload — supports tamper-evident UIDs. Reserved slot — content-hash UID scheme is a backlog item. SHACL leaves this optional.

Optional EIP-712 hex signature of the attestation's canonical payload. Reserved slot — signing client, canonical-payload spec, and verification pipeline come later. SHACL leaves this optional. See backlog: Attestation Signatures (EIP-712).

URL of the organization's banner image.

Name of this specific campus (if the organization is multi-campus).

The date when this engagement attestation was submitted. Convenience subproperty of prov:generatedAtTime.

Free-text description of the engagement — what the organization is doing, team size, approach, or any other context the claiming org wants to share.

Human-readable name of the resource collection or series. Equivalent to dct:title.

The calendar date on which the commissioning event occurred. Commissioning is a punctual event (a ceremony, a send-off gathering, a board decision), hence subPropertyOf prov:startedAtTime rather than a duration property.

The date-time when this commitment was declared. Subproperty of prov:generatedAtTime for PROV alignment.

Free-text description of the commitment — scope, approach, expected timeline, team size, or any other context the committing organization wants to share.

Date the organization was established or began meeting.

The date and time when the ministry activity started. Convenience subproperty of prov:startedAtTime. Use prov:endedAtTime for end time.

Free-form textual value for an assessment datum where the framework does not publish a controlled vocabulary (e.g., IMB 12 Healthy Church Characteristics, which records qualitative observations rather than scaled ratings). Use gc:datumValue for typed/controlled values; use this property only when the source framework's published rubric is qualitative.

The value of an assessment datum (literal or concept).

Primary contact email for this organization.

Date when the endorsement was granted. Convenience subproperty of prov:generatedAtTime.

Confidence score for the endorsement (0–1). Optional.
