The Ingestion Workflow service provides a wrapper functionality around the Apache Airflow functions and is designed to carry out preliminary work with files before running the Airflow Directed Acyclic Graphs (DAGs) that will perform actual ingestion of OSDU data.

The Unit Service provides dimension/measurement and unit definitions. Given two unit definitions, the service also offers conversion parameters in two different parameterizations.

The Dataset Service provides internal and external APIs to allow fetching storage/retrieval instructions for various types of datasets.

The CRS Catalog Service enables end-users to make CRS selections, search for CRSs given a number of constraints, download of the entire catalog for local caching, and access to various sub-sets of the catalog.

The Stream Storage Core (or internal) Service is a set of low level APIs for time-series data streams management.

The Indexer Queue Service provides a set of APIs that help in forwarding the messages to and from the Storage Service and Indexer Service.

The External Data Sources Data Management Service (EDS DMS) integrates with the Dataset Service to accept and proxy requests for obtaining retrieval instructions for externally resing datasets and proxy. The service is implemented in Java and provides an open API.

Domain Data Management Service focused on Well Planning and Well Execution

This CSV Parser DAG supports the ingestion workflow for CSV type files

The OSDU R2 Prototype includes a Workflow Engine, an implementation of Apache Airflow, to orchestrate business processes. In particular, the Workflow Engine handles ingestion of opaque and well log .las files in OSDU R2.

Legacy contribution from Energistics - only supports WITSML v2.0

The Manifest Ingestion DAG includes a Workflow Engine, an implementation of Apache Airflow, to orchestrate manifest/metadata ingestion via Storage Service

Open Subsurface Data Universe (OSDU) Wellbore-DDMS Worker is a python back-end service used internally by the OSDU Wellbore DDMS. It provides an internal API for accessing Wellbore bulk data.

The External Data Sources Data Management Service (EDS DMS) integrates with the Dataset Service to accept and proxy requests for obtaining retrieval instructions for externally resing datasets and proxy. The service is implemented in Java and provides an open API.
