What

Adds Data Fabric ontology binding to the agent context model: a context can carry one or more ontologies that the runtime fetches to ground Text2SQL.

• agent/models/agent.py — AgentContextResourceConfig.ontology_set (alias ontologySet), a list of DataFabricOntologyItem nested in the context alongside entitySet.
• platform/entities/_entity_ontology_service.py — DataFabricOntologyItem ({name, folderId, description?}) + EntityOntologyService for ontology file retrieval.
• platform/entities/_entities_service.py — get_ontology_file_async(ontology_name, file_type="owl", folder_key=None): validates name and file_type, hits GET datafabric_/api/ontologies/{name}/files/{type} on the authenticated, folder-scoped client.

Why

An ontology is part of a Data Fabric context — domain knowledge over the same entities — so it is configured inline on the context (a sibling of entitySet), mirroring how entities are bound. Each ontology carries its own folderId so it can live in a different folder from the entities.

Notes

• Additive + backward compatible: ontology_set defaults to None.
• No referenceKey on ontology items: ontologies are not solution-aware at this point, so there is no solution key to reference. The field is dropped from DataFabricOntologyItem — it was never populated or read (ontologies resolve by name + folderId). Backward compatible: configs that still send referenceKey are tolerated via extra="allow".
• Path-injection guard: ontology name (^[a-z][a-z0-9-]{0,63}$) and file_type (owl/r2rml/shacl/summary/context) are allowlisted before entering the URL.
• Tests: nested ontologySet parse/dump, required folderId per item, backward-compat default, full-AgentDefinition normalization; get_ontology_file_async covered for spec, folder header, file types, rejected name/type.
• Consumed by uipath-langchain PR feat: add integration service invocation support #911.
• Release: uipath → 2.11.17, uipath-platform → 0.1.83, pin uipath-platform>=0.1.83; lockfiles relocked.
