# SDS Financial Enterprise Ontology

Version **2026.08** is a runnable reference implementation of the enterprise architecture shown on the Semantic Data Services website. It is more than a diagram: the distribution contains modular OWL/RDF models, SKOS vocabularies, SHACL quality constraints, source mappings, JSON-LD context, sample data, competency questions and SPARQL queries.

## Start here

- Load `core/enterprise.ttl` as the ontology entrypoint.
- Use `catalog-v001.xml` in Protégé or another catalog-aware ontology tool so imports resolve to local files.
- Validate `data/sample-market-intelligence.ttl` with `shapes/financial-shapes.ttl` in a SHACL engine.
- Run the queries in `queries/` against the sample graph.
- Use `context/sds-financial-context.jsonld` when publishing API payloads as JSON-LD.

## Modules

| Layer | Modules | Purpose |
| --- | --- | --- |
| Enterprise | `core/upper.ttl`, `core/enterprise.ttl` | Shared identity, event, evidence, time, system and governance semantics plus the complete import closure. |
| Financial domains | party, instrument, market data, corporate event, portfolio, trading, risk, regulatory compliance, prediction and signal | Departmental meaning aligned through the enterprise backbone. |
| Cybersecurity | `domain/cybersecurity.ttl` | Connects assets, identities, vulnerabilities, techniques, incidents and controls to operational and portfolio risk. |
| Quality | `shapes/financial-shapes.ttl` | Executable constraints for market observations, orders, holdings, signals, LEIs and security incidents. |
| Vocabulary | `taxonomy/financial-taxonomies.ttl` | Controlled concepts for asset class, order side, signal direction and NIST CSF 2.0 functions. |
| Integration | `mappings/industry-alignments.ttl`, JSON-LD context | Reviewable mapping candidates for FIBO, FIX, ISO 20022 and MITRE ATT&CK plus API compaction. |
| Demonstration | sample graph, competency questions and SPARQL | A traceable market signal, portfolio exposure, order and cyber-impact scenario. |

## Design principles

1. **Modular by domain.** Teams can own and release departmental modules without fragmenting enterprise identity.
2. **Time and provenance first.** Source time, ingestion time, source record and generation activity stay queryable.
3. **Validation is executable.** SHACL turns data contracts and selected governance requirements into machine-checkable rules.
4. **AI receives evidence paths.** Predictions connect to instruments, events, portfolios, risk, model versions and explanations.
5. **Cyber risk reaches the business graph.** Security incidents can be traced from technique and asset to financial exposure.

## Standards posture

OWL 2 provides formal ontology semantics; SHACL validates RDF data graphs; SKOS represents controlled vocabularies; and PROV-O is the intended alignment point for detailed lineage. FIBO is the financial-industry reference ontology. FIX and ISO 20022 mappings are source/model-specific candidates and require validation against the exact versions used by a client. NIST CSF 2.0 and MITRE ATT&CK provide cybersecurity outcome and adversary-knowledge reference points.

This package does not redistribute FIBO, ISO 20022, FIX or MITRE content and is not a certified extension of those standards. Alignment triples and field mappings are implementation candidates, not claims of normative equivalence.

## Production adoption

Before production use, add client namespaces, resolve authoritative identifiers, confirm licensing for source standards, define access-control semantics, review OWL entailments, run SHACL regression tests, establish semantic versioning and stewardship, and threat-model every graph/AI interface. The sample contains fictional data and is not investment advice.
