SDK for origo

Configuration

When calling any classes interacting with the Origo API and there are no Config params passed to the constructor, a config object will be automaticly created for you based on environment variables

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:

1. Client Credentials: If you have added client_id / client_secret to the config. Or if you use the environment variable equivalent: ORIGO_CLIENT_ID / ORIGO_CLIENT_SECRET.
2. Username And Password: If you have added username / password to the config. Or if you use the environment variable equivalent: ORIGO_USERNAME / ORIGO_PASSWORD.

# keycloak user
export ORIGO_USERNAME=my-user

# keycloak password for ORIGO_USERNAME
export ORIGO_PASSWORD=my-password

# keycloak client
export ORIGO_CLIENT_ID=my-machine-client

# keycloak secret for ORIGO_CLIENT_ID
export ORIGO_CLIENT_SECRET=some-generated-secure-string


# overrides default environment (dev), but will be trumped by --env=<environment> on the commandline
export ORIGO_ENVIRONMENT=dev|prod

# If you are sending events and have been assigned a API key
export ORIGO_API_KEY=your-api-key

Getting Credentials:

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

TODO: Named profiles

If environment variables are not available, the system will try to load from a default profile: Located in ~/.origo/configuration

Usage

Table of contents:

• Upload data
• Sending events
• Create and manage event streams
• Creating datasets with versions and editions

Upload data

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 origo.data.upload import Upload
from origo.config import Config

origo_config = Config()

# If necessary you can override default values
origo_config.config["cacheCredentials"] = False

data_uploader = Upload(config=origo_config)

# Upload file 'data.json' to dataset-id/version/edition
dataset_id = "your-dataset-id"
version = "version"
edition = "20200115T130439"

filename = "data.json"

# Note! filename must be pointing to an existing file on your disk
upload_success = data_uploader.upload(filename, dataset_id, version, edition)

Download data

When downloading 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 origo.data.download import Download
from origo.config import Config

origo_config = Config(env="dev")

# If necessary you can override default config values
origo_config.config["cacheCredentials"] = False

data_downloader = Download(config=origo_config)

dataset_id = "your-dataset-id"
version = "1"
edition = "latest"

# Downloading a file
res1 = data_downloader.download(dataset_id, version, edition, "my/preferred/output/path")
print(res1)
# {
#     "downloaded_files": ["my/preferred/output/path/file_name.csv"]
# }

Sending events

In order to start sending events you will need access to an event stream. If such an event stream is already in place you are good to go. If not, you can create one either by using the sdk, or by using our command line interface.

from origo.event.post_event import PostEvent
from origo.config import Config

origo_config = Config()

# If necessary you can override default config values
origo_config.config["cacheCredentials"] = True

event_poster = PostEvent(config=origo_config)

dataset_id = "some-dataset-id"
version = "1"
event = {"foo": "bar"}

res = event_poster.post_event(event, dataset_id, version)
# res:
# {'message': 'Ok'}

# Method also supports list of dictionaries
event_list = [{"foo": "bar"}, {"foo": "bar"}]

res2 = event_poster.post_event(event_list, dataset_id, version)
# res2:
# {'message': 'Ok'}

Create and manage event streams

In order to create an event stream you need to have defined a dataset and a version, unless these already exist. Defining a dataset and a version can be achieved using the sdk, or you can use our command line interface. You do not need to define an edition in order to create an event stream.

from origo.event.event_stream_client import EventStreamClient


# Using default configuration for dev-environment
event_stream_client = EventStreamClient(env="dev")

dataset_id = "some-dataset-id"
version = "1"


# Creating a new event stream:
create_response = event_stream_client.create_event_stream(
    dataset_id, version
)
# create_response:
# {'message': 'Accepted'}


# Getting info about the event stream
event_stream_info = event_stream_client.get_event_stream_info(dataset_id, version)
# event_stream_info:
# { 'createdAt': '2020-01-29T07:02:32.598520+00:00',
#   'createdBy': 'jd',
#   'id': 'test-stream-manager/1',
#   'status': 'CREATE_IN_PROGRESS'
#   }

# Note! You must wait until the event stream has status=ACTIVE
#       before you can successfully send events to the stream


# Deleting the event stream
delete_response = event_stream_client.delete_event_stream(dataset_id, version)
# delete_response:
# {'message': 'Delete initiated'}

Creating datasets with versions and editions

from origo.data.dataset import Dataset
from origo.config import Config

origo_config = Config()

# If necessary you can override default values
origo_config.config["cacheCredentials"] = False

# Create a new dataset
dataset = Dataset(config=origo_config)

dataset_metadata = {
    "title": "Precise Descriptive Title",
    "description": "Describe your dataset here",

    },
    "publisher": "name of organization or person responsible for publishing the data",
    "processing_stage": "raw"
}

# create version for new dataset:
version_data = {"version": "1"}
new_version = dataset.create_version(new_dataset["Id"], data=version_data)

# new_version:
# { 'Id': 'precise-descriptive-title/1',
#   'Type': 'Version',
#   '_links': { 'self': { 'href': '/datasets/precise-descriptive-title/versions/1'}},
#   'version': '1'}

# create edition for new_dataset/new_version:
import datetime

# Note! edition-field must be ISO 8601 with utc offset
edition_data = {
    "edition": str(datetime.datetime.utcnow().replace(tzinfo=datetime.timezone.utc).isoformat()),
    "description": "My edition description",
    "startTime": "2019-01-01",
    "endTime": "2019-12-31"
}
new_edition = dataset.create_edition(new_dataset["Id"], new_version["version"], data=edition_data)

# new_edition
# { 'Id': 'precise-descriptive-title/1/20200115T130439',
#   'Type': 'Edition',
