Set up the OSDU extractor

The Cognite OSDU extractor is available as a Windows executable file (.exe file), a Windows installer (.msi file), and as a Docker container.

Before you start

1. Check the server requirements.

2. Make sure the extractor has the following access capabilities in the CDF project where you want to ingest data:

   • raw:read, raw:write, raw:list
   • files:read, files:write
   • extractionpipelines:read, extractionpipelines:write
   • extractionruns:read, extractionruns:write

3. Set up a CDF RAW database to serve as a target for the records ingested from OSDU. Make a note of the name.

4. Set up a data set to serve as a target for the data files transferred from OSDU. Make a note of the data set ID.

5. Create an environment file (.env) in the folder where you'll run the extractor. This file holds the credentials for connecting to CDF and OSDU. You can use the .env_example file or this template as a starting point:

    OSDU_SCOPE=f03fffff-9fff-4fff-9fff-2fffffffffff/.default openid profile offline_access
    OSDU_PARTITION=example-opendes

Run as a Windows executable file

1. Navigate to Data management > Integrate > Extractors and find the OSDU extractor's package for your operating system.

2. Download the zip file and decompress it to the same folder where you created the .env file.

3. Create a configuration file.

4. Open a command line window and run the executable file.

You stop the extractor by pressing Ctrl+C on your keyboard. The log file is stored in the configured path.

Run as a Windows service

1. Navigate to Integrate > Extract data in CDF and find the OSDU extractor installation package for your operating system.

2. Download and install the .msi file.

   Note

   We recommend that you don't change the default installation path.

3. Open the installation folder and edit the configuration file according to the configuration settings.

   Permission issues

   Set Modify permission under Properties in the installation folder to avoid permission issues.

4. Add the environment file (.env) you created above to the installation folder.

5. Run installer.exe to install the service as an automatic startup service.

   Tip

   • To manage the service, run starter.exe, stopper.exe, and log_presenter.exe.
   • To remove the extractor, run remover.exe.

Run as a Docker container

1. Sign in to Cognite's Docker registry. Contact Cognite Support to get access.

2. Save and edit the configuration file in the same folder as the .env file.

3. Optionally, run this command to make sure you're using the latest version of the OSDU extractor:

   docker pull eu.gcr.io/cognite-registry/osdu-connector:latest

4. Enter this docker run statement in the configuration file folder:

   docker run -v `pwd`/config.yaml:/cognite/config.yaml --env-file .env eu.gcr.io/cognite-registry/osdu-connector:latest

You stop the extractor by pressing Ctrl+C on your keyboard. The log file is stored in the configured path.

Explore the extracted data

You can explore the extracted data in CDF RAW and browse the files in the configured CDF data set.

Data stored in CDF RAW

Records ingested from OSDU are stored in the configured CDF RAW database. Adjust and clean up the data before transforming it into the CDF resource types.

A RAW table is automatically created for each configured OSDU kind, and a row is added for each extracted record. The record ID is used as the row key. Each root key in the record becomes a column.

Data stored in CDF Files

The OSDU files linked to the extracted records are saved in CDF Files. For instance, this can be CSV, LAS, or LIS files with the row data for a well-log record. You can transform the data to insert the rows into the corresponding CDF Sequence.

The extractor saves the files in CDF as is from the OSDU generic file service API or the DDMS API. The files are not further processed.

Monitor extractions

Set up extraction pipelines and set the external ID in the configuration file. The first time you run the extractor, it creates the extraction pipeline entries and logs succeeding runs with a success or failed status. You'll see the extraction runs as two sections on the Run history tab on the Extraction pipeline page.
