feat(agent): add ontology binding to Data Fabric context config by sankalp-uipath · Pull Request #1728 · UiPath/uipath-python

sankalp-uipath · 2026-06-17T09:22:00Z

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/entities.py — DataFabricOntologyItem ({name, folderId, referenceKey?, description?}), mirroring DataFabricEntityItem; exported from platform.entities.
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.
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 → 2.11.13, uipath-platform → 0.1.77, pin uipath-platform>=0.1.77; lockfiles relocked.

+# with a letter, max 64 chars. The name becomes a URL path segment.
+_ONTOLOGY_NAME_RE = re.compile(r"^[a-z][a-z0-9-]{0,63}$")
+# Allowed ontology component file types (also URL path segments).
+_ONTOLOGY_FILE_TYPES = frozenset({"owl", "r2rml", "shacl", "summary", "context"})


Whats the rationale here?

UIPath-Harshit · 2026-06-26T06:05:47Z

+            This method is currently experimental. Behavior and parameters are
+            subject to change in future versions.
+
+        Ontologies are served by the same QueryEngine service as entity SQL


Remove this implementation detail from the doc

UIPath-Harshit · 2026-06-26T06:06:44Z

+        self._validate_ontology_name(ontology_name)
+        self._validate_file_type(file_type)
+        spec = self._ontology_file_spec(ontology_name, file_type)
+        headers = {"Accept": "application/json", **header_folder(folder_key, None)}


Do you need this? Generally its handled by the spec method through base class.

+        return response.json()

+    @staticmethod
+    def _validate_ontology_name(ontology_name: str) -> None:


All these helper methods needs to move away from this file. I would suggest to create entities_ontology_service separately and consume just the ontology methods from this class.

Same for this. Move it to entities_ontology_service

Ontology is not solution aware at this point. Does it make sense for this to come from here?

Is the plan to add set of ontologies or single ontology ? Set doesnt make sense to me , but let me know if that decision has already been settled. cc: @milind-jain-uipath
