okdata-sdk is on PyPI: pip install okdata-sdk
When calling any classes interacting with the Origo Dataplatform API and there are no Config params passed to the constructor, a config object will be automaticly created for you based on environment variables
Default, will pick up configuration from current environment. The credentials is resolved automatically if you do not set a specific Auth config, in the following order:
- Client Credentials: If you have added client_id / client_secret to the config. Or if you use the
environment variable equivalent:
OKDATA_CLIENT_ID/OKDATA_CLIENT_SECRET. - Username And Password: If you have added username / password to the config. Or if you use the
environment variable equivalent:
OKDATA_USERNAME/OKDATA_PASSWORD.
# keycloak user
export OKDATA_USERNAME=my-user
# keycloak password for OKDATA_USERNAME
export OKDATA_PASSWORD=my-password
# keycloak client
export OKDATA_CLIENT_ID=my-machine-client
# keycloak secret for OKDATA_CLIENT_ID
export OKDATA_CLIENT_SECRET=some-generated-secure-string
# overrides default environment (dev), but will be trumped by --env=<environment> on the commandline
export OKDATA_ENVIRONMENT=dev|prod
# If you are sending events and have been assigned a API key
export OKDATA_API_KEY=your-api-key
username/password are synced with Oslo municipalities Active Directory so any user with an association can
use their personal account to access the SDK.
For client credentials please contact the data platform team. dataplattform[at]oslo.kommune.no
If environment variables are not available, the system will try to load from a default profile: Located in ~/.okdata/configuration

When uploading data you need to refer to an existing dataset that you own, a version and an edition. If these are non existent then you can create them yourself. This can be achieved using the sdk, or you can use our command line interface.
from okdata.sdk.data.upload import Upload
from okdata.sdk.config import Config
okdata_config = Config()
# If necessary you can override default values
okdata_config.config["cacheCredentials"] = False
data_uploader = Upload(config=okdata_config)
# Upload file 'data.json' to dataset-id/version/edition
dataset_id = "my-dataset-id"
version = "my-version" # example value: 1
edition = "my-edition" # example value: 20200618T114038
filename = "/path-to-file/data.json"
# Note! filename must be pointing to an existing file on your disk
upload_response = data_uploader.upload(filename, dataset_id, version, edition)
print(upload_response)
# {
# "result": True,
# "trace_id": "my-dataset-id-54a3c78e-86a3-4631-8f28-0252fe1c7c13"
# }The trace_id returned by the upload method can be used to "trace" the steps involved in the upload process:
from okdata.sdk.status import Status
...
status = Status(config=okdata_config)
trace_events = status.get_status(trace_id)
print(trace_events)
# [
# {
# "trace_id": "my-dataset-1a2bc345-6789-1234-567d-8912ef34a567",

# ]To download data you need to refer to a dataset that you have access to. This could be a public dataset, a restricted dataset you've been given access to, or a dataset that you own yourself. If the dataset is public, authenticating yourself is not necessary.
You will also need to refer to the specific version and edition of the dataset that you want to download. If this is your own dataset, make sure to create a version and edition before attempting to download it.

dataset.update_dataset(datasetid, data={ ... })
dataset.update_version(datasetid, versionid, data={ ... })
dataset.update_edition(datasetid, versionid, editionid, data={ ... })
dataset.update_distribution(datasetid, versionid, editionid, distributionid, data={ ... })
# Example: Update dataset metadata
dataset.update_dataset(
datasetid="precise-descriptive-title",
data={
"title": "Precise Descriptive Title",
"description": "Describe your dataset here",
"keywords": ["some-keyword", "another-keyword"], # Add another keyword
"accessRights": "public",
"license": "http://data.norge.no/nlod/", # Add licensing information
"objective": "Exemplify how to update an existing dataset", # Update objective text
"contactPoint": {
"name": "Your name",
"email": "[email protected]",
"phone": "999555111"
},
"publisher": "name of organization or person responsible for publishing the data"
}
)The update_dataset method also supports an optional partial keyword,
enabling partial updates when true:
dataset.update_dataset(
"my-dataset-id", {"description": "Only update description"}, partial=True
)
