TM Forum alignment

How the toolkit aligns generated ontologies to TM Forum SID, ITU-T X.733 alarms, 3GPP 5G NF schemas, and the 24 TMF Open APIs. Includes Phase 2B conflict resolution and ontology alignment + federation.


5. TM Forum alignment

Run with --phase tmf or as part of the full pipeline.

5G network functions (3GPP TS 23.501)

AMF · SMF · UPF · PCF · UDM · AUSF · NRF · NEF · gNB

Each is an OWL subclass of NetworkFunction with SID annotations, TMF API reference, and eTOM state machine values.

Alarm model (ITU-T X.733 / TMF642)

Six subtypes: CommunicationsAlarm, EquipmentAlarm, EnvironmentalAlarm, ProcessingErrorAlarm, QualityOfServiceAlarm, SecurityViolation. Full severity ladder (Critical → Cleared), state machine (Active → Acknowledged → Cleared), root cause chaining.

SID design patterns

Specification–Instance — XxxSpec table (catalog template) + instance table pair for Resource, Service, Product.

Composite — self-referential parent FK for hierarchies (NetworkSlice composed of NetworkFunctions).

Characteristic — polymorphic key-value extensibility table for any entity without schema changes.

TMF CQ tests (13 tests, all passing)

CQ Question Phase
CQ-TMF01 Which 5G NFs are Disabled/Locked and what resources depend on them? 1
CQ-TMF02 Which services are Active and which resources realise them? 1
CQ-TMF03 Which products are Active and which accounts and orders cover them? 1
CQ-TMF04 Which parties hold which roles and which agreements cover those relationships? 1
CQ-TMF05 Which SLA agreements are at risk from active alarms or service problems? 1
CQ-TMF06 Which Active or uncleared alarms exist by severity and root cause? 1
CQ-TMF07 Which KPIs breach thresholds with confidence score and derivation method? 1
CQ-TMF08 Full Resource to Service to Product to Customer traceability chain 1
CQ-TMF09 Which service orders are incomplete and what product orders triggered them? 1
CQ-TMF10 Open trouble tickets with resource/service impact and SLA breach status 2B
CQ-TMF11 Active network slice profiles with 3GPP S-NSSAI parameters and backing resources 2B
CQ-TMF12 Service quality reports showing SLA non-compliance with breached metrics 2B
CQ-TMF13 Outstanding and disputed customer bills per account 2B

Phase 2B: Multi-agent conflict resolution (--phase conflict)

Implements the 3-tier resolution chain from framework Section 10.1:

  • Tier 1 — SHACL axiom check: SQL-equivalent consistency rules that catch logically invalid states (e.g. operational_state=Disabled + admin_state=Unlocked). Escalates violations to Tier 3 automatically.
  • Tier 2 — Derivation-method priority: When two agents report conflicting values, the higher-priority derivation method wins: measured > inferred > imported > synthesized > default. Records PROV-O wasInvalidatedBy on the losing assertion.
  • Tier 3 — Human escalation queue: Unresolvable conflicts are inserted into tmf_conflict_event with escalated_to_human=1 and await review.

Produces: output/reports/conflict_resolution_report.json, output/shapes/conflict-resolution-shapes.ttl, output/jsonld/conflict-resolution-mcp-tools.json.

Three MCP tools: subscribe_to_events, resolve_assertion_conflict, get_conflict_queue.

Phase 2B: Ontology alignment & federation (--phase alignment)

Generates alignment axioms from the toolkit ontology to four external standards:

Standard Alignment type Classes aligned
DOLCE owl:equivalentClass, skos:closeMatch TmfEntity, DomainEvent, Party, Resource, Service, Agreement
FOAF owl:equivalentClass Party↔foaf:Agent, Individual↔foaf:Person, Organization↔foaf:Organization
Schema.org owl:equivalentClass, skos:closeMatch Organization, Product, ProductOrder, GeographicSite, CustomerBill, and 9 more
SOSA/SSN owl:equivalentClass, skos:closeMatch ObservationRecord↔sosa:Observation, Resource↔sosa:FeatureOfInterest, Agent↔sosa:Sensor

Produces: output/ontology/alignment.ttl (44 axioms), output/ontology/federation-config.ttl (5 named graph endpoints), output/ontology/federation-queries.sparql (5 multi-domain federated SPARQL examples).

Adding more TMF domains

  1. Add a table to db/tmf_schema.sql
  2. Add ontology_metadata rows in db/tmf_seed.sql with tmf_api_id, sid_domain, sid_abe
  3. Add the API to TMF_API_MAP in src/tmf_mapper.py
  4. Add 1-2 CQs to TMF_COMPETENCY_QUESTIONS in src/tmf_mapper.py
  5. Run python3 toolkit.py
