The Time-series Management Service allows users to ingest time-series bulk data as a array of data points. The data can be written for set of entities, properties and source. User access is restricted through entitlements. The data ingested supports bi-temporality.

The Time-series Publisher Core (or internal) Service is a part of time-series ingestion pipeline. Processes ingestion messaging queue and prepares data for Time-series Storage Core Service.

The Entity Management Service provides a set of APIs that enables the user to register OSDU Storage records as entities in Production DDMS, put them into relationships (hierarchies) and discover existing entities based on search criteria. Entities are defined through a type like well, meter, valve or platform. Two entities can have multiple entity relationships of a different types. The entities can be retrieved from the system in graph format with upward or downward graph traversal.

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 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.

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.

Repository for the Rock & Fluid Sample DDMS services for OSDU.
