Managed IT Service Graph

Client and provider identities

Authored composition-profile design for client and provider identities. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which client Dimension and provider organization does this graph describe? identity
2. Who is the current graph steward and what evidence authorizes administration? ownership
3. Which shared resources are referenced without transferring their ownership to this client? constraint

Service responsibility

Authored composition-profile design for service responsibility. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. What bounded service outcome is represented by this graph? definition
2. Which provider roles perform work and which party remains accountable? relationship
3. Which services or subcontractor obligations are explicitly outside this graph? exception

Asset identity and recognition

Authored composition-profile design for asset identity and recognition. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which authoritative identifier distinguishes this asset from similarly named resources? identity
2. Is the referenced item physical equipment, a virtual resource or a service endpoint? classification
3. How was the identity match observed and how are ambiguous matches quarantined? evidence

Service-to-asset dependencies

Authored composition-profile design for service-to-asset dependencies. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which service depends on which asset and in what direction? relationship
2. Under which condition and time interval is this dependency valid? constraint
3. Is the dependency declared, observed or inferred and what uncertainty remains? quality

Declared and observed state

Authored composition-profile design for declared and observed state. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. What desired state is declared by the configuration authority? state
2. What actual state was observed and by which method? measurement
3. How is a discrepancy retained without overwriting desired or observed state? validation

Bounded impact assessment

Authored composition-profile design for bounded impact assessment. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which directed dependency paths are traversed for this impact question? process
2. Which missing or stale edges limit the confidence of the impact result? quality
3. Who reviews an inferred impact before it authorizes an operational action? decision

Per-fact mastership

Authored composition-profile design for per-fact mastership. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which one owning Dimension and master system govern this fact path at this time? ownership
2. What approved evidence defines that master assignment and its precedence? authority
3. What happens when mastership is unknown or equally authoritative sources disagree? exception

Routed change lifecycle

Authored composition-profile design for routed change lifecycle. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. To which master endpoint is the proposed change routed under the current grant? process
2. Which version precondition and retry key protect the change from stale writes or duplication? constraint
3. What authoritative acknowledgement or readback proves that the change took effect? event

External work tracking

Authored composition-profile design for external work tracking. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which master task identifier links the work record to the affected service? identity
2. Which task fields are projections and which remain authoritative in the work system? state
3. How is an unavailable or failed task update kept distinct from a completed change? exception

Authorized cross-Dimension view

Authored composition-profile design for authorized cross-dimension view. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which recipient, purpose, objects and fields are permitted in this projection? access
2. How fresh is the projected view and when must it expire or be rechecked? temporal
3. How are revocation, deletion and derived sensitive relationships handled by this view? privacy

Provider change and handover

Authored composition-profile design for provider change and handover. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which authority acceptance and cutover evidence allow a new provider to take over? lifecycle
2. Which object identifiers and historical master references must survive handover? identity
3. Which previous grants and connector credentials must be revoked and verified? security

Graph completeness and audit

Authored composition-profile design for graph completeness and audit. Cited sources motivate distinctions; these field groups are not asserted to be mandated verbatim by those sources.

1. Which graph invariants have been checked and which checks remain unimplemented? validation
2. Which source revisions and approvals explain each material graph change? provenance
3. Which exported fields are preserved, transformed or lost by a destination adapter? interoperability
