The Structure Storage Core (or internal) Service enables entities and their relationships management.

The Domain Model Core (or internal) Service is a catalog representing the production domain. It has the information about supported entity types, associated properties with these entity types. A property contains information that describes the characteristics of a time-series, such as the unique property identifier (descriptor), data type, measurement, etc.

The Time-series Storage Core (or internal) Service is a final step in time-series ingestion pipeline. Processes published ingestion messages and stores data to the Time-series Storage.

Time-series Query Core (or internal) Service provides low level APIs for fetching data streams from Time-series Store.

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.

Airflow DAG for transformation from SEGY to OpenVDS

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

Azure Infrastructure provisioning scripts and templates

The Notification service allows interested consumers to subscribe to data and metadata changes using a publish/subscriber pattern.

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 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

[In development]

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

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 Indexer Service indexes the metadata store to support the Search Service.
