Palantir Core Workflow B — Ontology Objects & Actions
Overview
Query, filter, and mutate Ontology objects using the Foundry Platform SDK and OSDK. Covers listing objects with property filters, following links between object types, applying actions, and aggregating object data. This is the primary workflow for Ontology-driven applications.
Prerequisites
- Completed
palantir-install-auth setup
- An Ontology with configured object types, link types, and actions
- Familiarity with
palantir-core-workflow-a (data pipelines feed the Ontology)
Instructions
Step 1: List and Filter Objects (REST API)
import os, foundry
client = foundry.FoundryClient(
auth=foundry.UserTokenAuth(
hostname=os.environ["FOUNDRY_HOSTNAME"],
token=os.environ["FOUNDRY_TOKEN"],
),
hostname=os.environ["FOUNDRY_HOSTNAME"],
)
ONTOLOGY = "my-company"
result = client.ontologies.OntologyObject.list(
ontology=ONTOLOGY,
object_type="Employee",
page_size=20,
order_by="hireDate:asc",
properties={"department": "Engineering"},
)
for obj in result.data:
p = obj.properties
print(f"{p['fullName']} | {p['department']} | hired {p['hireDate']}")
Step 2: Search Objects with Filters
search_result = client.ontologies.OntologyObject.search(
ontology=ONTOLOGY,
object_type="Employee",
where={
"type": "and",
"value": [
{"type": , : , : },
{: , : , : },
],
},
page_size=,
)
